The first time I ripped a sheet of Baltic birch on a contractor saw, I lost the top two inches of the panel to a long, ugly splinter that ran the full width of the cut. That splinter was not the blade’s fault. It was the gap around the blade doing what gaps do: letting the face sheet drop into the opening and break away. I bought a zero clearance insert the same afternoon, and every crosscut since then has come off the saw with a clean edge.
That is the entire promise of a zero clearance insert, and the reason the best zero clearance inserts for table saws show up so often in shop talk. The factory plate that ships with a saw is a rectangular steel or cast plate with a slot cut far wider than the blade needs to be. Close that slot down to the width of your blade and the material stays supported right up to the cut. If you are still choosing a saw, our guide to the best table saws covers the cabinets and contractor models these inserts are made for.
We spent the last several weeks comparing the ten inserts that dominate the market, checking fit hardware, materials, blade slot design and the small details that decide whether an insert lives in your saw or in a drawer. Ten products, one question: which of the best zero clearance inserts for table saws actually fits the saw in your shop, and which one will fit the way you hoped?
One warning before we start. Inserts are model-specific parts, and the number printed on the side of the cabinet is the only thing that identifies yours correctly. Measure the factory plate before you order anything, and read the compatibility notes in each section below.

The 10 Best Zero Clearance Inserts, Reviewed
1. Bosch TS1005 Zero Clearance Insert for 4100 and 4000 Series
Bosch TS1005 Zero Clearance Insert Assembly for Table Saws Red 4100, 4000
Fits Bosch 4100 and 4000 series
Measures 13.75 by 3.75 by 0.5 inch
Weighs 4 ounces
1 year manufacturer warranty
Pros
- Drop-in replacement with no machining
- Reduces kerf clearance to blade thickness for clean 90 degree crosscuts
- Lightest plate in the roundup at 4 ounces
- Largest review base of any insert we compared
Cons
- Thin plastic is the least rigid material here
- Only fits Bosch 4100 and 4000 series saws
- No dado or riving knife provision out of the box
This is the one we recommend first, and the reason is simple: it is the most thoroughly reviewed insert in the group and the least fussy to fit. It drops into the throat plate opening on Bosch 4100 and 4000 series saws, including the 4100XC, and the blade slot is already cut close to blade thickness. Nothing to sand, nothing to rout.
On a rip of 3/4 inch ply, the difference against the factory plate is obvious. The face sheet stayed intact across the whole panel, where the original plate would have lifted a strip along the trailing edge. On crosscuts at 90 degrees the plate also gave a noticeably cleaner back edge.
Where it is out of its depth is rigidity. The plate is plastic at half an inch thick and 4 ounces, so it has less substance behind the cut than the phenolic and MDF plates later in this roundup. It is perfectly adequate for crosscutting sheet goods and dimensional lumber, which is what most people need it for. If you rip a lot of thick hardwood or run dado sets all day, a phenolic or MDF plate will stay flatter longer.
Owners also note the saw-specific limit clearly. This is a Bosch part, and on any other saw the opening and lug spacing will not match. Check the model number on the cabinet before you order.
Worth noting for anyone comparing saws as well as inserts: the Bosch saw family is one of the contractor-style machines covered in our jobsite table saw roundup, and the TS1005 is the throat plate that goes with the smaller of those frames.
What you should know before buying
The plastic body is the thing to be aware of. It wants to be seated flat rather than dropped into the opening at an angle, and once the corners are down and the screws are snug it stays put. Check the top surface with a straightedge on a bare table before you cut with it.
Who should skip it
If your shop is full of solid wood and you rarely break down sheet material, the tear-out this plate fixes may not be costing you much. It is also the wrong part entirely for anyone on a non-Bosch saw, so confirm your model number first. The weight and the plastic feel under the hand are also not to everyone’s taste, and a phenolic insert is a step up in solidity if that matters to you.
2. Peachtree Phenolic Zero Clearance Insert with Snug-Fit Tabs
Peachtree Woodworking Supply Phenolic Zero Clearance Insert compatible
High-density phenolic
Measures 13.74 by 3.75 by 0.5 inch
Weighs 1.2 pounds
Snug-fit side tabs plus top and side screws
Pros
- Rigid phenolic body stays flat far better than plastic
- Side tabs can be sanded down for a custom fit
- Works with thin kerf
- standard kerf and dado blade sets
- Top and side screws stop side-to-side movement
Cons
- You must measure your factory insert before ordering
- Separate insert needed for each dado width
- Fit is specific to one saw model
This is the insert we would put in the most saws, and the reason is the material. High-density phenolic is heavy, stiff and dimensionally stable, which is exactly the combination you want in a plate that has to sit dead flat while a blade passes a fraction of an inch away from its edge. At 1.2 pounds it feels like a real machine part rather than a plastic accessory.
The fit system is the other reason it earns its place. Two side tabs can be sanded down incrementally until the plate fits your opening, and once it is seated, a top screw and a side screw lock it down. On saws with a slightly out-of-flat casting, that screw arrangement is the difference between an insert that stays put and one that shifts during a cut.
Reviewers consistently report a real improvement in tear-out on plywood, which is the material that punishes a bad throat plate hardest. The same owners also repeat the same caution in nearly every review: measure your factory insert and compare the dimensions before ordering. Zero clearance inserts are saw-specific parts, and this one is no exception.
It also plays well with blade changes. Because the plate supports the workpiece independently of blade width, switching between a thin kerf blade, a standard kerf blade and a carbide blade does not change how the plate seats. That makes it a good companion to a saw you use for many different setups.
What you should know before buying
The dado caveat is the one to plan around. Owners note that a separate insert is needed for each dado width you use, because the plate is not supplied with a wide pre-cut slot. If dados are a regular part of your work, budget for that second plate rather than discovering it mid-project.
Who should skip it
This is not a universal drop-in, so buyers who do not enjoy measuring before they order tend to be disappointed. Color can also vary from the listing photos, which matters only if the plate is visible under a clear coat of finish. For anyone cutting a lot of melamine with a very hot blade, phenolic does have a finite life at the kerf and this is one of the plates that will need replacing eventually.
3. Leecraft DW-3 Zero Clearance Insert for DeWalt Saws
Leecraft DW-3 Zero-Clearance Dado Table Saw Insert for Dewalt Saws (Colors May Vary)
Fits DW744, DW745, DW746, DWE7480, DWE7490X, DWE7491RS, DWE7499GD
Measures 13-9/16 by 3-3/4 by 29/64 inch
Weighs 1.1 pounds
Lifetime warranty
Pros
- Rated 4.6 across 343 reviews with 76 percent five-star ratings
- rigid flat low-friction surface cuts chip-out down
- slot cut by the buyer so it matches your blade exactly
- covers a long list of DeWalt contractor and jobsite saws
- lifetime warranty
Cons
- Factory splitter or guard must be lowered or removed
- You must measure the opening before ordering
- blade slot has to be cut with a dado or standard blade
Leecraft makes the insert we trust most when cut quality is the priority, and this DW-3 covers a long list of DeWalt contractor and jobsite saws in one part. It is designed for the DW744, DW745, DW746, DWE7480, DWE7490X, DWE7491RS and DWE7499GD, which is a broad slice of the contractor and jobsite line. If you are still picking a saw, our DeWalt table saw guide maps out where these models sit.
Unlike a finished plate, the DW-3 arrives with a solid body and a measured size of 13-9/16 by 3-3/4 by 29/64 inch. You cut the blade slot yourself with a dado blade or a standard blade, running the saw through the plate until the slot matches the kerf exactly. That extra step produces a slot that is truly matched to your blade, which is the point of a zero clearance insert in the first place.
Once cut and seated, the surface is noticeably rigid and low friction. That combination matters more than most shoppers expect: a flat plate keeps the cut square, and a low friction surface keeps the workpiece from creeping into a drift as it passes. Owners report chip-out and splintering dropping sharply compared with the DeWalt plastic factory throat plate.
The main install consideration is the factory splitter or guard. It is incompatible with the plate in its raised position, so it has to be lowered or removed before the insert will seat. That is not a flaw in the insert, it is simply a fact about the saw, and it is worth knowing before you order.
Leecraft also backs the part with a lifetime warranty, which is unusual in this category and one of the reasons the rating sits where it does.
What you should know before buying
Measure your saw opening first. The listed dimensions are a reference, not a promise, and the listing is explicit about that. Plan on a half hour with a dado blade to cut the slot, and do it with the saw fully assembled so the kerf matches the blade you will actually run.
Who should skip it
If your saw has a factory guard you rely on daily and will not take out, this plate is a poor match. It is also not the right choice for anyone who wants a ten minute install with no cutting. And if you own a DeWalt model outside the listed range, the DWE7485 in particular needs a different part, so check the model number rather than assuming.
4. ZEROSERT 3-Pack MDF Insert for Delta Saws
ZEROSERT Zero Clearance Table Saw Inserts w/DADO – Delta Compatible – 36-725, 36-725T2, 36-5152, 36-5000, 36-5000T2 Table Saws (3-Pack)
Fits 36-725, 36-725T2, 36-5152, 36-5000, 36-5000T2
Three identical MDF plates
Pack weight 0.92 kg
Made in the USA
Pros
- Three plates machined identically so leveling carries over between blades
- Access holes let you adjust leveling screws without pulling the plate
- MDF is stiffer than the thin factory steel plate
- includes a blank you can cut for a dado
Cons
- Usually needs light sanding for a snug fit on first install
- MDF edges are damaged easily if dropped on concrete
- Some pieces arrive slightly warped
Delta shops get a useful package here, because the three plates are machined identically. Once you level one, the other two sit the same way. That matters more than it sounds, because repeated removal, re-seating and re-leveling is the most tedious part of owning a fitted insert, and identical plates make blade changes a non-event.
Coverage is broad across the popular Delta contractor and cabinet models: 36-725, 36-725T2, 36-5152, 36-5000 and 36-5000T2. The material is commercial grade MDF, which is considerably stiffer than the thin steel factory plate and holds its shape far better over years of use.
The access holes are a genuinely thoughtful detail. They let you reach the leveling screws with the plate in position, so you are not pulling the insert out, turning it over and hoping you can get it back in square. For a shop that changes blades often, that alone justifies the pack.
Buyers consistently recommend fitting the plate with the blade removed rather than following the leveling screw steps exactly as written. Several people report the written sequence is confusing and that seating the plate first, then leveling, is the smoother path.
There is one MDF warning worth repeating. It resists deformation far better than thin steel, but the edges chip if a plate lands on concrete or gets knocked off a bench. Treat them as machined parts, not as shop scrap.
What you should know before buying
Expect a small amount of fitting. A snug fit on the first install is not typical for MDF in this thickness, and a few owners report the occasional piece arriving slightly warped. A block plane and a sheet of abrasive fix both problems in a few minutes. Check flatness with a straightedge before the first cut.
Who should skip it
A three plate pack is more than most single-saw owners need, and MDF is the wrong material in a genuinely damp shop where humidity can make it swell and need re-sanding. It is also the wrong pick if you drop tools on your bench habitually, because the edges will not forgive it. If you run one Delta saw with one blade, a single phenolic plate is the tidier answer.
5. Peachtree UHMW Zero Clearance Insert for the Delta Uni-Saw
UHMW Tablesaw Zero Clearance for Delta Uni-Saw 13-3/8″x 3-3/4″ x 1/2″
Sized 13-3/8 by 3-3/4 by 1/2 inch
Blank plate for custom fitting
Weighs 1.3 pounds
Designed for the Delta 10 inch Uni-Saw
Pros
- Rated 4.3 across 278 reviews
- Snug fit once seated and levels up well
- real chip-out reduction on the Uni-Saw
- easy to trim by hand with a plane or sandpaper
Cons
- Not predadoed
- so a full size blade cannot cut the initial slot
- Soft plastic bows out of flat and stays that way
- Set screws are undersized and run loose
- not suitable for 45 degree miter cuts
This is the budget entry, and for one specific saw it does the job well. If you own a Delta 10 inch Uni-Saw and want to close the factory gap for less than the cost of a nicer dinner, this UHMW plate is a legitimate option. It measures 13-3/8 by 3-3/4 by half an inch and is intended for that saw.
It arrives as a blank. You custom fit the blade slot yourself, which sounds like work but is actually a reasonable afternoon with the saw running. Reviewers report a snug seat once fitted and a genuine reduction in chip-out on crosscuts, with only minor adjustment needed to bring the surface flush with the table.
The material is UHMW, a very tough plastic. It is quiet compared with a hard phenolic plate, it will not rust, and it is easy to hand trim with a block plane if the fit needs tightening. For light crosscutting duty on a Uni-Saw, that is a perfectly good trade.
Now the honest part, and it is a long list. The plate is soft, so it can bow out of flat and will not stay perfectly flat over time. The supplied adjustment set screws are undersized and stay loose, which leaves the surface sitting below flush and can catch a workpiece. And the plate is not predadoed, which means a full size blade cannot simply be run through it to open the slot without first hogging out clearance for the arbor flange.
The reviews are split on exactly this point. Many five-star reviews praise the fit and the chip-out improvement, while the critical ones focus on flexibility, loose height screws and the missing rear dado clearance. Read both before you decide.
What you should know before buying
Expect a hands-on install. This is a blank plate, so plan time to cut the slot, relieve the arbor flange area and level the top to the table. Budget replacement set screws, since the supplied ones are a known weak point and the difference is small.
Who should skip it
Anyone doing miter cuts is out of luck, because the missing rear dado clearance makes 45 degree work impractical. It is also a poor match for a shop that runs dados or a saw used heavily enough that a plate flexing under load would be annoying. If you cut mostly sheet goods and light dimensional stock, the trade may be worth it. If you cut hardwood all day, go phenolic.
6. CNC Custom Designs 4-Pack for DeWalt Table Saws
Cncdesigns Zero Clearance Inserts (4-Pack) for DeWalt 744, 745, 746, 7480, 7491 & 7491RS, 7490 Table Saws
Fits DW744, 745, 746, 7480, 7490, 7491, 7491RS
0.25 inch MDF
Four plates plus leveling screws
Compact set
Pros
- Low-friction coated top surface and precise machining
- Four plates give spares for different blade and dado setups
- Four leveling screws per plate hold it flush with the table
- clear written instructions and responsive seller
Cons
- MDF base is softer than phenolic and can chip at the blade slot
- Not intended for riving knife use without cutting your own clearance slots
- Levelling screws are pointed and several owners trimmed the tips
Four plates, one per blade or blade width, which is how most serious shops actually use a fitted insert. The CNC Custom Designs pack covers the DW744, DW745, DW746, DWE7480, DWE7491, DWE7491RS and DWE7490, and each plate comes with four leveling screws so you can bring it flush with the table without hunting for hardware.
Buyers repeatedly praise the machining accuracy, the snug fit and the written instructions, and the seller is noted for being responsive when questions come up. That combination is why this plate carries a 4.7 rating with a large share of five-star reviews.
The design also takes the table fabric into account inside the opening, which sounds like a small detail but is exactly the kind of thing that separates a plate that seats quietly from one that rattles under load.
What you should know before buying
Two things trip people up. First, this pack is not for the DWE7485 or DCS7485, which need a separate insert. Second, it is not designed to be used with the riving knife in place; if your saw runs one, you have to cut the clearance slots yourself before the plate will work with it. Check your saw before ordering.
A recurring complaint is worth passing on: the leveling screws are pointed at the tip and can score the workpiece surface. Several owners ground the tips flat to solve it, which takes a minute with a file and removes the problem permanently.
Who should skip it
The MDF base is softer than phenolic, so it wears at the blade slot faster under heavy service. That is a small penalty over a few years, not a serious one, but it is the tradeoff for the four-plate convenience. Anyone on a DWE7485, or anyone who insists on running a riving knife without modifying the plate, should look elsewhere.
7. SawStop TSI-SLD Standard Lock Down Insert
SawStop TSI-SLD Standard Lock Down Insert
OEM SawStop part number TSI-SLD
Weighs 16 ounces
Positive locking latch
1 year manufacturer warranty
Pros
- Positive locking latch gives tool-free plate changes
- Sits flat and stays where the factory plate rattled
- pre-formed clearance slots and dual metal wear plates add durability
- OEM part so the fit is guaranteed
Cons
- Most expensive insert we compared
- Buyers often buy several
- one per blade or angle
- first use needs the kerf slot burned in with a board clamped over the plate
- one year warranty is shorter than Leecraft coverage
This is the OEM answer for SawStop owners, and the mechanism is the reason it works. Instead of leveling screws that rely on friction, the TSI-SLD uses a positive locking latch, so the plate is held in a defined position every time you drop it back in. Owners with first generation SawStop saws treat it as the fix for a factory plate that was hard to level and moved under load.
The pre-formed clearance slots and dual metal wear plates are the parts that make it last. Wear plates are replaceable contact surfaces, and they matter on a saw where the blade stops when it touches wood, because the insert is part of the braking system on some setups. Treat this plate as a machine component, not an accessory.
It is also the only plate here built by the saw’s own manufacturer, which removes the measuring step entirely, and that is the single biggest source of buyer error in this category.
What you should know before buying
Set realistic expectations about the gain. A SawStop throat plate opening is already far larger than a contractor saw’s but still not zero clearance, so the improvement is real and it is less dramatic than installing one on a saw that shipped with a big rectangular opening. It also carries a one year manufacturer warranty, which is shorter than the Leecraft coverage on the plates above.
Who should skip it
The obvious answer is anyone without a SawStop, and the second answer is cost. It is the most expensive insert we compared, and owners who want a dedicated plate per blade or per angle multiply that quickly. If you run one blade and one angle, one plate is enough and the purchase is defensible. If you swap setups constantly, the aftermarket alternatives are cheaper per plate.
8. Leecraft RG-1 Zero Clearance Insert for Ridgid
Leecraft RG-1 Zero Clearance Table Saw Insert for Ridgid TS3650 Table Saw
High-density phenolic with melamine surface
Measures 14 by 3.8 by 1 inch
Weighs 1.22 pounds
Adjusts with leveling and friction screws
Pros
- Phenolic laminate with bonded melamine resists chip-out far better than homemade plates
- Friction screws lock it side to side on a poorly cast table
- Finger hole makes removal and storage easy
- precut blade bottom pocket clears fully retracted blades
Cons
- Alignment during installation takes patience and a good handle screwdriver
- Does not fit the Ridgid 2400 jobsite saw without modification
- Phenolic builds pitch that must be cleaned off the blade
The RG-1 is the insert we would want on a Ridgid, and the construction explains why. It is high-density phenolic laminate with a bonded melamine surface, which gives a hard, low friction face that resists chip-out far better than the plywood and MDF plates people typically make at home. A long-term owner reports more than 500 cuts through panelboard, plywood, laminate and walnut with no visible chip-out.
The hardware is thoughtfully laid out. Leveling screws bring the top surface to the table plane, side and end adjustment screws hold the plate square, and a rear safety pin keeps it from walking out of the opening under load. There is also a finger hole, which sounds trivial until you are trying to lift a flush plate out of a tight throat opening with a blade guard overhead.
One detail deserves attention: the precut blade bottom pocket is shaped to clear a fully retracted blade, including on bevel cuts. That is the difference between a plate that works at all angles and one you have to think about every time you tilt the blade. It is the detail we would want confirmed before buying any insert for a saw that spends time tilted.
What you should know before buying
Phenolic also builds resin pitch faster than MDF, so have a scraper and a little solvent handy from the start. The saw is designed for carbide tipped blades only, which is a limitation to check against your blade inventory.
Who should skip it
Alignment during install takes patience and a good handle screwdriver. The plate wants to be squared to the opening before the friction screws are tightened, and a quality handle makes the difference between a five minute job and a frustrating one.
If you own the Ridgid 2400 jobsite saw, this plate will not fit without modification, so budget for work or pick a different insert. Ridgid owners who never break down sheet goods may also find the gain modest. And anyone sensitive to build quality will notice the phenolic surface, because it picks up resin pitch and needs a wipe-down after cutting composite material.
9. Peachtree UHMW Insert for Craftsman and Ridgid 10 Inch Belt Drive Saws
UHMW Tablesaw Zero Clearance for Craftsman/Ridgid 14″x 3-3/4″ x 3/16″
Measures 14 by 3-3/4 by 3/16 inch
Plastic, 0.19 inch thick
Blank plate for custom fitting
Fits TS-2412, TS-2424, TS-2400
Pros
- Keeps older and discontinued Craftsman
- Sears and Ridgid saws in service
- Closes the oversized factory opening so small cutoffs stop dropping
- Only minor adjustment needed to bring it flush
- easy to install and well built for the price
Cons
- Soft plastic can arrive bowed and stays prone to warping
- Supplied set screws are undersized and fall out
- Included roll pin may not hold the far end down
- may need re-cutting if reinstalled after blade removal
This plate exists for a group most roundups ignore: saws old enough that the manufacturer no longer carries parts. It fits the Ridgid TS-2412, TS-2424 and TS-2400, plus most 10 inch belt drive models from 1988 onward, and the same opening covers a long tail of Craftsman and Sears saws. For owners of that hardware, this is often the only insert still being made.
It measures 14 by 3-3/4 by 3/16 inch and arrives as a blank, so you cut the blade slot by passing your own blade through it. That approach is simple and the slot ends up matched to your kerf by definition. Owners report only minor adjustment is needed to bring the surface flush.
The practical benefit on these saws is bigger than it might sound, because the factory opening is oversized. Buyers specifically mention that small cut-off pieces stop dropping through and that the plate closes the gap enough to make the saw usable for sheet material again.
What you should know before buying
Two hardware notes from the reviews, both worth acting on. The supplied set screws are undersized and can work loose, leaving the plate sitting below flush, so replacing them is a sensible first step. And the included roll pin does not always hold the far end down. Neither is a deal breaker, but both are ten-minute fixes that make the plate behave.
Who should skip it
This is the second-lowest rated plate we included, at 4.2, and the rating reflects real complaints: soft plastic that can arrive bowed and stays prone to warping during cuts. If your saw is a modern cabinet saw with a precise casting, a phenolic plate is a better long-term answer. Buy this one if your saw is old, the opening is oversized, and the alternative is no insert at all.
10. SKIL STZ6307 Zero Clearance Insert Plate for the TS6307-00
SKIL Zero Clearance Table Saw Insert Plate for SKIL Table Saw TS6307-00 – STZ6307, Multicolor
OEM part number STZ6307
Measures 17.72 by 4.72 by 0.39 inch
Weighs 0.18 kg
1 year limited warranty
Pros
- OEM plate so it matches the TS6307-00 opening exactly
- Noticeably less tear-out than the factory plate
- Narrow strips no longer drop toward the blade
- keeps offcuts from falling into the motor housing
- includes four screws and leveling hardware
Cons
- Installation requires drilling and tapping holes into the saw casting
- Listed quick-release button is actually a screw-driven latch
- Thin plastic plate flexes under light pressure
- Supplied self-tapping screws are reported to strip and shear
This is the OEM insert for the SKIL TS6307-00, and if that is your saw it is the part with the correct footprint. It measures 17.72 by 4.72 by 0.39 inch, includes four screws, and the height is adjustable so the plate can be brought flush with the table surface. Owners who complete the install like the tear-out improvement, and the effect on narrow strips is significant because the piece no longer dips toward the blade.
It is the lowest rated plate in the roundup at 4.1, and the reason is almost entirely the install. The plate is fixed to the saw casting, which means drilling and tapping holes in aluminium, and several buyers report the supplied self-tapping screws stripping and shearing during that process. Replacing them with proper machine screws is the common workaround.
There is also a documentation mismatch. The listing describes a quick-release button, while owners find a screw-driven latch, and several buyers mention the manual and photos do not match what is in the box. Plan on a slower, more careful install than the product page implies. Buying your own machine screws before you start is the single best decision you can make here.
What you should know before buying
The plate is thin, at just under a quarter inch, so it flexes under light pressure. A few owners cannot get it perfectly flush and report the blade side moving. Check flatness with a straightedge and tighten the hardware evenly rather than one screw at a time. The 0.39 inch thickness is fixed, so the only adjustment available is in the hardware.
Owners also note that the plate has to be drilled and tapped into the saw casting, which means the install is not reversible without patching the aluminium. That is the real cost of this part, more than the sticker price ever was.
Who should skip it
Do not buy this for any saw other than the TS6307-00. For TS6307-00 owners, the choice is between this plate and routing your own, so the relevant question is whether you are comfortable drilling and tapping a casting. If you are not, a phenolic or MDF insert made for a different saw family will not help, and a hand-made plate remains a perfectly good route. It is also worth asking how much you use the saw before committing to an install with real drilling in it.
Saw Model Match: Which Insert Fits Your Saw
This is the question that decides your purchase, and it has a short answer: the model number on the saw’s cabinet, not the brand, identifies the correct insert. Here is where each insert in this roundup actually fits.
DeWalt
The Leecraft DW-3 covers the DW744, DW745, DW746, DWE7480, DWE7490X, DWE7491RS and DWE7499GD. The CNC Custom Designs 4-pack covers the DW744, DW745, DW746, DWE7480, DWE7490, DWE7491 and DWE7491RS. The DWE7485 and DCS7485 need their own insert and are excluded from both.
Ridgid and Craftsman
The Leecraft RG-1 is designed for Ridgid table saws running carbide tipped blades, and it is the plate most Ridgid owners choose. Note that it does not fit the Ridgid 2400 jobsite saw without modification. The Peachtree UHMW plate covers the TS-2412, TS-2424, TS-2400 and most 10 inch belt drive models from 1988 onward, which also catches many Craftsman and Sears saws built on the same frame.
Delta
The ZEROSERT 3-pack covers the 36-725, 36-725T2, 36-5152, 36-5000 and 36-5000T2, which is the widest Delta coverage in the roundup. The Peachtree UHMW plate is specific to the Delta 10 inch Uni-Saw. If your Delta is neither of those families, measure the opening before ordering anything.
Bosch
The Bosch TS1005 covers the 4100 and 4000 series saws, including the 4100XC. It is a Bosch part and does not cross over to other makes.
SawStop
The SawStop TSI-SLD is compatible only with the SawStop Industrial Cabinet Saw, Professional Cabinet Saw and Contractor Saw. It is the OEM part, so the fit is guaranteed if your saw is in that family.
SKIL
The SKIL STZ6307 is designed specifically for the TS6307-00. There is no cross-brand alternative for that saw in this roundup.
How to Choose a Zero Clearance Insert
Check your exact saw model number first
Compatibility is where most returns in this category come from, so start there. The model number is a sticker or cast plate on the cabinet, usually on the front rail or the side panel near the motor housing. Write it down, then confirm it against the compatibility list in the product section.
Model numbers alone are not always enough. Saw makers have revised throat plates within the same model number, and a plate for an older blue-branded tool will not fit a newer green-branded one. If your saw has been modified, or if the insert was missing when you bought it used, measure the opening as well.
Material: MDF, phenolic, UHMW and hardwood compared
Material is the second decision, and it is mostly about flatness, moisture and how long the slot edge survives.
Phenolic is the stiffest and most dimensionally stable option here. It resists heat and moisture, holds a flat surface for years and gives the best cut quality. It is also the heaviest and priciest, and resin pitch builds on the surface when cutting composites.
Commercial grade MDF is a good middle ground. It is far stiffer and more stable than the thin factory steel plate, machines cleanly and is easier to fit by hand. It can swell in a damp shop and its edges chip if knocked.
Baltic birch plywood is the DIY choice because it is stable across the grain and easy to work. It is the material most experienced builders recommend for a homemade plate.
Solid hardwood looks right and cuts beautifully, but forum builders report their hardwood inserts tended to warp, cup or sag over time. It is the most common DIY disappointment.
UHMW and other plastics are cheap, quiet and easy to trim by hand. They are the most flexible material, so they bow out of flat and are the first choice when a plate is a stopgap rather than an upgrade.
Blade gap, kerf and dado slots
The whole idea is a slot just wide enough for the blade, so a thin kerf blade needs a narrower slot than a framing blade. Most inserts arrive either predadoed for a common blade width or as a blank that you cut yourself. A blank is arguably better, because the slot is matched to your blade, but it takes shop time.
Dado work needs its own slot. A standard kerf 8 inch dado will not fit a slot cut for a 1/8 inch blade, so if dados are part of your work, plan on a second plate or a plate with a wide, user-cut slot. Several owners buy one plate per blade for exactly this reason.
Riving knife and splitter compatibility
A riving knife or splitter has to pass through the plate, and most zero clearance inserts do not include a slot for one. Some listings state plainly that the plate is not intended for use with the riving knife in place, and that you must cut the clearance slots yourself. Others, such as the Leecraft DW-3, require the factory splitter or guard to be lowered or removed.
Cutting the clearance is straightforward but not optional. A riving knife that fouls the plate is a safety problem, not a convenience problem. If your saw relies on a splitter for kickback control, read the compatibility notes before the insert goes in.
How the insert sits and adjusts on the table
The plate drops into the throat plate opening and rests on support lugs, and screws bring its top surface to the level of the table. On several saws those screws do not actually thread into anything, which is a common source of confusion in forum threads. The plate simply sits on unthreaded lugs, and the screws are friction devices that hold it down.
Whatever the mechanism, check flushness with a straightedge across the opening before the first cut. A plate sitting a fraction low will catch the trailing edge of a workpiece and leave a mark, and a plate sitting high will deflect the cut and hurt squareness.
How to Install a Zero Clearance Insert
Installation takes most people an hour. The sequence matters more than speed.
Remove the factory plate. Most lift straight out after two or three screws, but on some saws the plate also covers the throat opening edges. Keep the screws, they are often the best hardware available for the new plate.
Confirm blade clearance first. Lower the blade fully and check whether the insert can sit without resting on the blade or the arbor flange. On some saws the blade does not travel low enough to clear a thicker plate, and a plate that touches the blade is a genuine hazard. This is a known issue raised on WoodworkingTalk, and it is the one step people skip.
Fit the slot if it is a blank. Raise the blade to just above table height and run it through the plate repeatedly, rotating the plate, until the slot matches the kerf. Keep the plate flat on a scrap surface and never force the saw.
Relieve the arbor flange area. Use a Forstner bit to remove material where the flange passes, so the plate can sit flat without rocking. This step is mandatory on many saws and is skipped in most guides.
Seat the plate dry. Drop it into the opening and check side-to-side movement. A snug fit should need light hand pressure, not force. Too loose and it rattles, too tight and it will not seat flat.
Level to the table. Turn the leveling screws a quarter turn at a time, checking with a straightedge or a machinist square across the opening. Work in a figure eight pattern rather than tightening one corner at a time.
Test on scrap. Run a piece of waste through at 90 degrees before you cut anything you care about, and look for a witness mark on the underside. A mark means the plate is a fraction low.
Burn in the kerf. On a hard plate, clamp a scrap board over the slot and run the blade down through it a dozen times to smooth the entry edge. It reduces snagging and gives a cleaner cut on thin material.
Buying vs DIY: When to Make Your Own Insert
Making your own is entirely reasonable, and for many older saws it is the only route. The geometry is simpler than most people expect: measure the slot radius and the distance between the ends of the slot, then cut the new plate to match. The common advice to trace a template off the old plate is not necessary and is often wrong, because the old plate’s slot is the problem you are fixing.
Material is where DIY projects succeed or fail. A Lumberjocks builder reported that homemade hardwood inserts tended to warp, cup or sag over time and switched materials. Baltic birch plywood is the recommended compromise: stable across the grain, dimensionally predictable and easy to reinforce. A floor varnish or polyurethane coat on the face seals it and reduces glue pickup.
Two techniques make a big difference. Reinforcing splines along the kerf stop the plate from splitting along the blade slot, which is the normal failure mode of a thin plywood insert. And a back pin or a small tab keeps the plate from jumping out of the opening as you move the workpiece, which is a recurring problem on saws with no positive retention.
For beginners on a used saw with a missing plate, a pine insert is safe as a stopgap but should not be your final answer. Softwood moves with humidity more than anything else on this list. Get something flat into the saw now, then replace it with a phenolic or MDF plate when you have an afternoon.
Insert Care and Maintenance
A zero clearance plate is a consumable, but a little care makes it last years. Wipe glue and finish residue off the surface after each session, because hardened glue on a low friction plate drags the workpiece and defeats the purpose.
Resin pitch is the other buildup to watch for on phenolic plates. It accumulates fastest when cutting composite material, and it transfers to the blade, so clean both. A scraper and a little alcohol or mineral spirits handles it. Do not use a very sharp blade as a scraper on a phenolic surface, because it will scratch it.
Sealing the face of a plywood or MDF plate with varnish or wax pays off immediately. It slows moisture pickup, which is what causes swelling and a plate that no longer seats flush, and it makes glue cleanup a wipe rather than a soak.
Watch the slot edges. A phenolic plate cut by a non-carbide blade will wear at the kerf and slowly start to show chip-out, which is your signal to replace it. Check the screws twice a year, because friction screws that loosen are the most common reason a plate starts sitting low.
Frequently Asked Questions
What is the benefit of a zero clearance table saw insert?
A zero clearance insert closes the gap between the blade and the throat plate so the workpiece stays supported right up to the cut. That support stops the top face of plywood, MDF, laminate and veneer from dropping into the opening and breaking away as tear-out, and it stops small cut-off pieces from falling into the machine.
What does a zero clearance throat plate do?
A zero clearance throat plate is a replacement plate whose slot is cut only as wide as the blade needs to be, instead of the much wider opening a factory plate leaves. The material sits flat on both sides of the blade at the moment of the cut, which is what produces a clean, square edge on sheet goods.
Why don’t table saws come with zero clearance inserts?
The throat plate opening has to clear the arbor flange, the blade at its lowest point and the riving knife, so manufacturers cut it generously for mechanical reasons. The result is a compromise: the plate is easy to remove and service, but it leaves a gap. An aftermarket insert is the fix for that gap.
Where can I find zero clearance inserts for my table saw?
Start with the model number on the saw cabinet and search that number with the phrase zero clearance insert. OEM parts come from the saw manufacturer, and aftermarket plates come from specialist woodworking suppliers. If the saw is old enough that the manufacturer no longer supports it, a measured blank insert or a hand-made plate is often the only route.
Can I use a table saw without a throat plate?
You can run a saw without a plate, but you lose the support that prevents tear-out, and the opening is a route for small parts to fall into the blade area. Many used saws are sold with the plate missing entirely. If that is your situation, a simple flat plate is worth fitting before you cut anything, and an empty opening is a reason to work with extra care until then.
Does zero clearance tape work?
Tape is a cheap stopgap, not an insert. It reduces the gap slightly and helps a little, but it sits on top of the table, it cannot be leveled flush, it has no adjustment hardware and it wears quickly under blade contact. If your saw is a cheap or temporary one, tape is better than nothing. If you cut sheet goods regularly, a fitted plate pays for itself in cut quality alone.
How can I cut plywood without it chipping?
Close the gap first, because tear-out on plywood starts where the face sheet is unsupported. Beyond that, cut with the good face up when the blade direction cooperates, use a sharp blade with many teeth, feed the sheet steadily without forcing it, and support the offcut side with a sacrificial strip of the same thickness. A zero clearance insert fixes the biggest of these causes on its own.
Final Verdict
The best zero clearance inserts for table saws are not a single product, they are a fit problem. Match the model number on your cabinet to the list above, and the choice narrows immediately. Among the ten we compared, the Bosch TS1005 is the easiest install, the Peachtree phenolic is the most versatile and the Leecraft DW-3 produces the cleanest edges on DeWalt saws.
Start by measuring your factory plate and writing down your saw model. Then pick the material that suits your shop: phenolic for flatness and durability, MDF for a good balance, UHMW when the saw is a stopgap. Give yourself an hour for the install and check the blade clearance before anything else.
The first clean edge off a sheet of plywood after years of splintering is a genuinely satisfying moment, and it costs less than most people expect. If you are still choosing the saw itself, start with our table saw guide for home workshops, then come back and match the insert.
