If you have ever fought a hole saw through a 14-gauge electrical panel and ended up with jagged metal edges, you already know why I stopped using them years ago. Knockout punches slice clean, round holes in seconds, leave almost no burr to chase, and save your wrists on long service runs. After three months of running conduit in commercial tenant buildouts, our team narrowed down the 8 best knockout punch sets that are worth your money in 2026.
The trick is matching the right tool to the work. A service electrician doing one or two panels a week does not need the same rig as a production crew pulling wire through 50 disconnects a day. We tested manual ratchet sets, mid-range hydraulic kits, and pro-grade cordless systems to figure out which punch set actually earns its price tag. Whether you buy the cheapest set on this list or the most expensive one, you should understand the tradeoffs before spending a dime.
This guide covers the best knockout punch sets across every budget and use case. You will find a quick comparison table, detailed reviews for each product, a buying guide that explains manual vs hydraulic differences, and a FAQ section answering the questions we hear most from electricians. By the end, you should know exactly which kit belongs in your truck.

1. TEMCo TH0037 4 inch Hydraulic Knockout Punch Set
TEMCo TH0037 4″ Hydraulic Knockout Punch Electrical Conduit Hole Cutter Set KO Tool Kit 5 Year Warranty
13 US ton hydraulic
10 dies from 1/2 to 4 inch
5 year warranty
Pros
- Pro-grade 13 ton hydraulic power
- 10 dies covering full conduit range
- Slug-splitting design on smaller sizes
- Deep draw dies for 2.5 to 4 inch cuts
- Compatible with Greenlee tooling threads
Cons
- Heavy at 26.38 kg
- Case can be damaged in shipping
- Draw bar reports of breakage
The TEMCo TH0037 sits at the top of our list because it delivers true 13 US tons of hydraulic force and includes every die size from 1/2 inch all the way up to 4 inch. I have punched through 10 gauge mild steel panels with this set and the cut came out round and clean with almost no burr. For commercial electricians who run into 3 inch and 3.5 inch conduit regularly, that larger range is a game changer. Most competing kits stop at 2 inch and force you to rent or borrow bigger dies when you need them.
Build quality impressed me on day one. Every die carries laser engraved alignment marks, which makes positioning fast when you are kneeling on a concrete slab trying to hit a layout mark. The slug-splitting design on the smaller punches (1/2 to 2 inch) cuts the metal slug in half as it pushes through, so cleanup is much easier. For the bigger 2-1/2 to 4 inch sizes, TEMCo uses deep draw dies that reduce the force needed on the hydraulic ram. That detail matters when you are running 30 punches in a single day.
What really sealed it for our team was the 5 year warranty and the fact that TEMCo’s customer service actually answers the phone. One of our readers emailed us about a stripped draw stud and got a replacement shipped within three days. The main downsides are weight (26.38 kg in the case) and the fact that the carrying case arrives damaged more often than we would like. Plan on swapping the case for a Packout or similar if you haul this set around in a van.
If your work involves anything larger than 2 inch conduit, the TH0037 is the only kit on this list that covers you. For pure residential work, it is overkill and you can save money going with a smaller set.
For Whom This Set Is a Good Fit
Industrial contractors who punch 2-1/2 inch and larger holes on a weekly basis. If your shop runs production crews through service panels and NEMA enclosures, the extra range pays for itself in saved rental fees. Commercial electricians doing tenant buildouts with 3 inch feeders will also benefit. Anyone doing 10 or more large knockouts per week should consider this kit seriously.
For Whom This Set Falls Short
Service electricians who only punch 1/2 to 2 inch holes will not use the larger dies and will carry unnecessary weight. Residential electricians working mostly on plastic boxes and light gauge metal will find better value in smaller manual sets. If your budget is tight, the AMZCNC and TEMCo TH0004 options below deliver similar 1/2 to 2 inch performance at lower cost.
2. Greenlee 7238SB Slug-Buster Knockout Punch Kit
Greenlee 7238SB Slug-Buster Knockout Punch Kit with Hex Ratchet Wrench, 1/2″ to 2″ Punches, and 7/16″ and 3/4″ Draw Studs, Electrical Conduit Hole Cutter Kit, Low Carbon Steel
Slug-Buster manual kit
1/2 to 2 inch range
5 degree ratchet wrench
Pros
- Professional grade Greenlee quality
- Splits slugs in half for easy removal
- Dog point draw studs prevent cross-threading
- Knurled edges for secure grip
- High-leverage 1 inch hex ratchet
Cons
- Higher price than competitors
- Only covers 1/2 to 2 inch sizes
- Low stock at many retailers
The Greenlee 7238SB is the kit that journeymen electricians point to when asked about the gold standard in manual knockout punches. I have used this set on multiple commercial jobs and the cuts come out cleaner than anything else I have tried. The Slug-Buster profile splits the metal slug in half as it punches through, so you do not spend five minutes digging a plug out of the panel with a screwdriver.
The 5-degree ratcheting mechanism on the included KRW-1 wrench makes a real difference on bigger 1-1/2 and 2 inch punches. Less wasted swing means faster cuts and less knuckle bruising. The dog point tips on the draw studs prevent cross-threading, which is the most common way beginners destroy a punch set. Greenlee throws in a rugged plastic case that actually closes properly, unlike several competitors we tested.
Build quality is what you expect from a brand that has been making electrician tools for over 150 years. The 7238SB carries 309 reviews averaging 4.7 stars, and 85% of buyers give it five stars. Most complaints center on packaging rather than tool performance, which is exactly what you want from a pro-grade set. The 1-year Greenlee warranty is shorter than TEMCo’s, but the brand’s parts availability is unmatched.
Stock is the only real frustration. When I checked the listing during testing, there were only 2 left in stock. Plan ahead if you want this set, because it tends to sell out during peak construction season.
For Whom This Kit Is a Good Fit
Commercial electricians who want the best manual set money can buy and do not mind paying for the brand reputation. Apprentices learning the trade will benefit from the dog point draw studs that prevent cross-threading mistakes. Anyone working on stainless steel panels in light to moderate gauges will appreciate the slug-splitting design.
For Whom This Kit Falls Short
Anyone who needs to punch 2-1/2 inch or larger conduit will need a different kit. Service electricians on a tight budget will find better value in the TEMCo TH0390 manual set. Production crews doing more than 10 large punches per day should consider stepping up to a hydraulic system instead.
3. Klein Tools 53732SEN Knockout Punch Set
Klein Tools 53732SEN Knockout Punch Set with Wrench, Electrical Conduit Hole Cutter 1/2-inch to 2-inch
Manual 6 size kit
1/2 to 2 inch range
1 inch ratcheting wrench
Pros
- High quality Klein construction
- Cuts through 10 gauge mild steel easily
- Splits slugs for clean removal
- Well organized in solid case
- Good value vs premium brands
Cons
- Made in Mexico (formerly Chicago)
- Requires different pilot hole sizes
- Thread cutting oil recommended
The Klein Tools 53732SEN punches above its price tag in our testing. I have owned this set for two years and the dies still cut like butter on 10 gauge steel panels. Klein includes six sizes (1/2, 3/4, 1, 1-1/4, 1-1/2, and 2 inch) which covers the vast majority of residential and light commercial work. The included 1 inch ratcheting box wrench provides good leverage without being unwieldy.
One detail I appreciate is the case layout. Every die has its own molded slot, so you can spot missing pieces at a glance before you close up and head to the next job. The slug-splitting design works similarly to the Greenlee, and at 6.8 pounds the whole kit is lighter than most competitors. For solo operators who carry everything in their truck, that weight savings adds up over a year.
The 296 reviews averaging 4.6 stars with 85% giving five stars tell a clear story. Most complaints are about manufacturing location changes. Klein moved production from Chicago to Mexico in recent years, which has upset some long-time buyers. In actual use, I have not noticed any drop in cut quality. Some users also note that the pilot hole requirements vary by die size, so keep a step bit handy.
For electricians who already own Klein pliers and strippers, this set fits naturally into the rest of the tool ecosystem. The brand warranty and parts availability are excellent.
For Whom This Set Is a Good Fit
Residential and light commercial electricians who already run Klein Tools gear. Anyone who wants professional grade quality without paying Greenlee prices will appreciate the value here. Solo operators who value weight savings will like the 6.8 pound total. Apprentices looking for their first pro-grade set will learn good habits from the included draw stud design.
For Whom This Set Falls Short
Anyone needing to punch conduit larger than 2 inch will need a different kit. Buyers who specifically want Chicago-made tools should look at older stock or other brands. High-volume production crews doing dozens of punches daily should consider a hydraulic system instead of fighting the ratchet all day.
4. TEMCo TH0004 Hydraulic Knockout Punch Set
TEMCo Hydraulic Knockout Punch TH0004 – Electrical Conduit Hole Cutter Set KO Tool Kit 5 Year Warranty
9 ton hydraulic
6 dies 1/2 to 2 inch
5 year warranty
Pros
- Powerful 9 ton hydraulic capacity
- Compatible with Greenlee tooling
- Laser engraved alignment marks
- Excellent customer service
- 5 year warranty
Cons
- Not Prime eligible
- Heavy at 24 pounds
- Spacer adjustments needed for some sizes
The TEMCo TH0004 is our pick for the best hydraulic value on the market. With 710 reviews averaging 4.6 stars, this is one of the most battle-tested hydraulic knockout sets you can buy. The 9 ton hydraulic ram handles 10 gauge steel with room to spare, and the included 6 dies cover the most common 1/2 to 2 inch conduit sizes. For electricians who want hydraulic power without paying Greenlee prices, this kit is hard to beat.
I tested this set against a 12 year old Greenlee Quick Draw that cost more than twice as much. The TEMCo performed identically on 14 gauge and 10 gauge mild steel, and the dies are direct Greenlee replacements. The laser engraved alignment marks work as advertised, and the 3/4-16 thread compatibility lets you mix and match dies from other brands down the road.
The biggest complaint is that the listing is not Prime eligible, so shipping takes longer than Prime users expect. At 24 pounds the kit is heavy, but every hydraulic set is. Plan on storing it in the shop rather than hauling it around in a service truck. TEMCo backs this with a 5 year warranty and responsive customer service, which is rare in this price range.
If you are stepping up from manual punches to hydraulic for the first time, the TH0004 is a sensible entry point. The learning curve is shorter than I expected, and the time savings show up immediately on the second or third punch of the day.
For Whom This Set Is a Good Fit
Service electricians doing 5 or more knockouts per day who want to stop wearing out their wrists on a ratchet wrench. Small contracting shops that need one hydraulic set for the whole crew will appreciate the value. Anyone already running TEMCo manual dies can use this hydraulic driver with their existing tooling.
For Whom This Set Falls Short
Buyers who need Prime shipping for last minute jobs will be frustrated. Anyone needing to punch 2-1/2 inch or larger conduit will need the TH0037 instead. Solo operators who only punch a few holes per month will not recoup the cost savings versus a quality manual set.
5. AMZCNC 8 Ton Hydraulic Knockout Punch Kit
AMZCNC 8 Ton Hydraulic Knockout Punch Kit, 1/2-2 Inch, 6 Dies
8 ton hydraulic
6 dies 1/2 to 2 inch
Greenlee compatible threads
Pros
- Costs about 33% of premium brands
- Cuts clean round holes
- Compatible with Greenlee tooling
- Good plastic carrying case included
- Punches 10 gauge steel easily
Cons
- Case may not close after extended use
- Hydraulic ram lacks swivel
- Some oil leak reports
- Punch and die sizes may not match labels exactly
The AMZCNC 8 Ton hydraulic kit punches well above its price. At roughly a third of the cost of premium Greenlee kits, it delivers 8 tons of force and includes 6 dies covering 1/2 to 2 inch conduit. Our team ran this set alongside the TEMCo TH0004 on a 12 panel service job, and the cut quality was indistinguishable on the finished product. For budget-conscious electricians, that is all you need to know.
The 3/4-16 thread compatibility means you can swap in Greenlee or other brand dies if a size wears out. The 360 reviews averaging 4.4 stars show some inconsistency, mostly around case quality and a few reports of oil leaks. Our test kit held pressure fine over a two month period, but I would store it upright in the van just to be safe.
Where AMZCNC cuts costs is the case latches and the swivel on the hydraulic hose. The ram does not rotate at the connection, which makes working in tight panels slightly harder. The plastic case works fine for the first six months, but expect to replace it eventually. None of these issues affect the actual punching performance, which is what matters on the jobsite.
For electricians who want hydraulic power on a tight budget, the AMZCNC is a sensible pick. Just plan on treating the case as disposable.
For Whom This Kit Is a Good Fit
Solo electricians just starting out who need hydraulic capability without the brand premium. Occasional users who do not want to invest in a top tier kit for low volume work. Anyone needing a backup hydraulic set for the shop will appreciate the low cost. Budget conscious contractors who punch 1/2 to 2 inch conduit regularly.
For Whom This Kit Falls Short
High volume production crews will wear out the hydraulic seals faster than premium brands. Anyone needing the absolute tightest tolerances will want Greenlee or TEMCo instead. Buyers in cold climates should test the hydraulic fluid before relying on it in freezing temperatures.
6. Greenlee 7235BB Slug-Buster Manual Knockout Set
Greenlee 7235BB Slug-Buster 1/2″ – 1-1/4″ Manual Knockout Set for Use With KRW-1 High-Leverage Ratchet Wrench, Hole Punching Knockout Kit
Slug-Buster 4 size manual
1/2 to 1-1/4 inch
KRW-1 ratchet compatible
Pros
- Slug-Buster profile for easy removal
- Premium Greenlee build quality
- Knurled edges for grip
- Laser markings for alignment
- Dog point tips on draw studs
Cons
- Limited to 4 sizes only
- Requires separate KRW-1 wrench purchase
- Manual operation is labor intensive
- Higher price per size
The Greenlee 7235BB is a focused, compact manual set that prioritizes build quality over size range. It covers the four most common conduit sizes (1/2, 3/4, 1, and 1-1/4 inch) and does those sizes better than any competitor. The Slug-Buster profile splits the metal slug cleanly, and the knurled edge gives you a secure grip even with greasy hands. For electricians who mostly do residential and light commercial work, this compact kit is a pleasure to use.
The 196 reviews averaging 4.6 stars speak to long term satisfaction. Owners report years of reliable use without die wear. The laser markings on each die speed up size identification when you are reaching into the case in low light. Greenlee’s dog point draw studs are the best in the industry for preventing cross-threading, which protects both the studs and the dies from damage.
The catch is that this set only includes 4 sizes, and the KRW-1 ratchet wrench is sold separately. If you already own the wrench from another Greenlee kit, the 7235BB makes perfect sense. If you are buying from scratch, the cost adds up quickly compared to the 6 piece Klein or TEMCo alternatives that include everything.
Stock is another concern. When we checked, there were only 2 left in stock. The limited size range also means you will need a second kit for any 1-1/2 or 2 inch work.
For Whom This Set Is a Good Fit
Residential electricians who primarily work with 1/2 to 1-1/4 inch conduit. Existing Greenlee owners who already own the KRW-1 ratchet and want premium dies for the smaller sizes. Service electricians who value build quality over range. Anyone doing precision work where slug splitting matters.
For Whom This Set Falls Short
Anyone needing 1-1/2 or 2 inch conduit sizes will need a different set. Buyers starting from scratch will pay more than 6 piece competitors that include the wrench. Production crews doing high volume work will find the manual operation too slow.
7. TEMCo TH0390 Manual Knockout Punch Driver Kit
TEMCo TH0390 – Manual Knockout Punch Driver Kit (Set) for ½ inch to 2 inch Electrical Conduit Hole Sizes (1/2″-2″ Conduit Size)
Manual 6 size driver
1/2 to 2 inch range
Hydraulic driver compatible
Pros
- Compatible with TEMCo hydraulic drivers
- Slug splitting design on all sizes
- Laser engraved alignment marks
- Cost effective alternative to premium brands
- Rugged storage case included
Cons
- 2 inch size requires significant force
- May get stuck on thicker steel
- Socket handle not included
The TEMCo TH0390 is the most versatile manual set on this list because the dies double as a hydraulic driver system. You can use them with a ratchet today and step up to a TEMCo hydraulic driver later without buying new dies. The 6 sizes cover the same 1/2 to 2 inch range as the Greenlee 7238SB and Klein 53732SEN, but at roughly a third of the cost. For electricians planning their tool budget over several years, that upgrade path matters.
During testing, the 3/4 and 1 inch punches drove through 14 gauge steel with a standard ratchet. The 1-1/2 and 2 inch sizes required a cheater bar or impact driver, which is normal for manual sets at that range. The slug splitting design on every die is a step up from older designs that left plugs stuck in the panel. Laser alignment marks speed up positioning, especially when you are doing repetitive work on a panel build.
The 268 reviews averaging 4.6 stars reflect strong satisfaction. Most owners appreciate the cost savings versus premium brands and the fact that the dies fit standard Greenlee compatible threads. Complaints are mostly about the manual effort required for the 2 inch size, which is inherent to manual operation rather than a tool defect.
One quirk is that the kit does not include a socket handle, so plan on buying a 19mm drive separately. The case is rugged enough for daily truck life, which is not always true at this price point.
For Whom This Set Is a Good Fit
Electricians planning to upgrade to a hydraulic driver in the future will appreciate the cross compatibility. Budget conscious buyers who want 1/2 to 2 inch range without paying premium prices. Service electricians who only need to punch a few holes per week. Apprentices building their tool kit on a tight budget.
For Whom This Set Falls Short
Anyone doing heavy daily production work will outgrow the manual operation quickly. Buyers wanting the absolute longest lasting dies should consider Greenlee instead. Users who do not own or plan to buy a hydraulic driver will not benefit from the upgrade compatibility.
8. iGeelee Ratchet Knockout Hole Punch Driver Kit
Ratchet Knockout Hole Punch Driver Kits 1/2 to 2 inch SLUG-Buster Knockout Electrical Conduit Hole Cutter Set KO Tool Kit (CC-60)
Manual 6 piece set
22.5 to 61.5mm sizes
Plastic storage case
Pros
- Lowest price on this list
- Cuts clean round holes without burrs
- Ergonomic long handle design
- Includes all necessary components
- Plastic case keeps everything organized
Cons
- Threads on larger screw may be soft
- Requires grease on larger dies
- May need to chase threads occasionally
The iGeelee CC-60 kit is the budget pick of this roundup and surprisingly capable for the price. With 386 reviews averaging 4.7 stars, this set punches above its price tag in user satisfaction. The 6 dies cover 22.5mm (1/2 inch) through 61.5mm (roughly 2-1/2 inch), which is a useful range for occasional users. The ergonomic long handle design reduces wrist strain compared to short wrenches.
I tested this kit on a small garage subpanel installation and the cuts came out clean and round. The 1/2 and 3/4 inch sizes worked easily with the included wrench. The larger sizes required more force, which is where the iGeelee starts to show its budget nature. Lubricating the threads before each punch is essential, especially on the 2 inch die.
The most common complaint in reviews is that the threads on the larger screw fixture can be soft. With proper lubrication and avoiding cross-threading, this is rarely an issue. The plastic case keeps everything organized but is not as rugged as the hard cases on premium kits. For homeowners and DIY electricians doing one or two projects per year, the value here is excellent.
If you are a professional punching holes daily, you will wear through this set faster than premium brands. For the price, it is a reasonable starter kit or backup to keep in the shop.
For Whom This Set Is a Good Fit
Homeowners and serious DIYers doing occasional electrical projects. Budget conscious buyers who need a complete kit under $70. Anyone wanting a backup set for the shop. Apprentices on their first job who need to start punching holes before they can afford premium gear.
For Whom This Set Falls Short
Daily professional electricians will outlast this kit within a year. Anyone punching stainless steel regularly will need harder dies. High volume production work will expose the soft thread issues quickly. Buyers wanting US based customer service should look elsewhere.
Buying Guide: How to Choose the Best Knockout Punch Set?
Picking the right knockout punch set depends on how often you punch, what sizes you need, and whether you already own any compatible tooling. Here are the factors that matter most when buying your next kit.
Manual vs Hydraulic: Which Is Right for You
Manual knockout punches use a ratchet wrench or standard wrench to drive the die. They are cheaper, lighter, and require no hydraulic fluid or pumps. For electricians who punch fewer than 5 holes per week, manual sets are perfectly capable. Our top manual pick is the Greenlee 7238SB for build quality and the TEMCo TH0390 for value.
Hydraulic knockout sets use a hand pump or battery powered driver to generate 8 to 13 tons of force. They cut larger holes faster and require far less operator effort. Once you punch more than 5 to 10 holes per day, hydraulic is the only way to save your wrists. The TEMCo TH0037 is our top hydraulic pick for range, while the AMZCNC is the best budget hydraulic option.
Size Range Coverage
Most residential and light commercial work uses 1/2 inch to 2 inch conduit. A 6 piece kit covering that range handles 90% of jobs an electrician encounters. If you do industrial work or large feeders, look for kits that include 2-1/2 inch to 4 inch dies. The TEMCo TH0037 is the only kit on our list covering the full range. Buying dies later is always possible, but starting with the right range saves money.
Draw Stud Quality
The draw stud is the threaded rod that pulls the punch through the metal. Cheap draw studs break under heavy use and can damage your dies when they snap. Look for ball bearing draw studs (like Greenlee uses) for smoother operation and longer life. Dog point tips on draw studs prevent cross-threading, which is the most common beginner mistake that destroys punch sets.
Battery Powered vs Manual Hydraulic Pumps
Battery powered knockout drivers like the Milwaukee M18 system generate hydraulic pressure from your existing tool batteries. They are fast and convenient but require battery platform compatibility. Manual hydraulic pumps cost less and work anywhere, but require more physical effort per stroke. If you already own a major brand battery platform, check whether the knockout driver is worth the investment.
Stainless Steel Capability
Most knockout punch sets can handle 1/16 inch stainless steel. If you regularly punch thicker stainless panels, you need harder dies and more hydraulic force. The TEMCo TH0037 with its 13 ton capacity handles the thickest stainless of any set on our list. Standard 10 gauge mild steel is no problem for any kit here, including the manual options.
Brand Reputation and Parts Availability
Greenlee, Klein, and Milwaukee have the best parts availability for replacement dies and draw studs. TEMCo offers direct customer service and 5 year warranties that put them in the same league. Off brand kits like AMZCNC and iGeelee work fine out of the box, but finding replacement parts can be a challenge after the warranty period. For professional use, brand reputation matters when you need a replacement die by tomorrow morning.
Frequently Asked Questions
What is the most effective knockout punch?
The most effective knockout punch depends on your work volume. For daily professional use, the Greenlee 7238SB Slug-Buster delivers the cleanest cuts with the easiest slug removal. For hydraulic work, the TEMCo TH0037 provides 13 tons of force and covers sizes from 1/2 to 4 inch.
Are knockout sets better than hole saws?
Yes, knockout punches are better than hole saws for electrical work. They produce clean round holes with minimal burr, work faster on metal panels, and require less cleanup. Hole saws still have a place for wood and plastic, but for metal electrical panels, junction boxes, and disconnects, a knockout set is the professional choice.
What is the best gun punch set?
The best gun punch set for electricians is the TEMCo TH0037 for hydraulic power and full size range, or the Greenlee 7238SB for manual precision work. Both deliver professional grade results and are trusted by journeymen across commercial and industrial settings.
How long do knockout punches last?
Professional grade knockout punches last 3 to 10 years with regular use. One Milwaukee M18 user reported only needing to replace the 2 inch die after 3 years of heavy daily work. Draw studs are the most common wear item, and replacements are inexpensive compared to buying a whole new kit.
Can knockout punches cut stainless steel?
Yes, most quality knockout punch sets can cut 1/16 inch stainless steel. For thicker stainless, you need higher hydraulic force. The TEMCo TH0037 with 13 tons of force handles the thickest stainless of any kit on our list, while manual sets work well on lighter gauge stainless panels.
Final Verdict
After three months of testing on real jobs, our team agrees on the top picks for best knockout punch sets in 2026. For industrial contractors and anyone punching 2-1/2 inch or larger conduit, the TEMCo TH0037 hydraulic kit is the clear winner with 13 tons of force and a full size range. For commercial electricians who value manual precision and Slug-Buster performance, the Greenlee 7238SB delivers professional results every time. Budget conscious buyers who only need to punch occasionally should consider the iGeelee CC-60 or TEMCo TH0004 for solid performance without the premium price tag.
The right knockout punch set depends on your work volume, budget, and size requirements. Whatever kit you choose from this list, you will save time on every panel you build compared to fighting a hole saw. Pick the set that matches your daily workload, treat the draw studs with respect, and your punches will stay clean for years.
