When I first picked up an M12 cordless ratchet to bleed a set of motorcycle brakes, I expected a compromise. I ended up buying six more M12 tools by the end of the month. That is the short version of why Milwaukee’s M12 platform has stuck around: it delivers real working torque in a body that fits where 18V tools physically cannot reach. After spending weeks with ten of the most recommended M12 tools on the market in 2026, I can tell you exactly which ones earn a spot in your bag, which ones to skip, and which trade each tool was honestly built for.
This guide is for anyone comparing M12 against M18, anyone already invested in a 20V system from another brand and wondering whether dipping a toe into M12 actually makes sense, and anyone who has simply had enough of wrestling full-size cordless tools into tight engine bays and electrical panels. We pulled signals from real users on r/MilwaukeeTool and trade forums, layered in our own hands-on time, and built a list of the ten best M12 tools you can actually buy right now.
Top 3 M12 Picks at a Glance for September 2026

1. Milwaukee M12 FUEL 2-Tool Combo Kit (2598-22) – Best Overall M12 Starter
Milwaukee Electric Tools 2598-22 M12 Fuel 2 Pc Kit- 1/2″ Hammer Drill & 1/4″ Impact
350 in-lb torque
1/2 inch hammer drill + 1/4 inch impact driver
4.0Ah battery included
Pros
- Brushless POWERSTATE motor delivers strong power for a 12V platform
- Compact head length is excellent for overhead and ladder work
- Includes both a hammer drill and an impact driver for full versatility
- REDLITHIUM 4.0Ah battery gives solid runtime across most jobs
Cons
- Hammer drill is underpowered for concrete or large hole saws
- Carry bag zipper is the weakest part of the package
If you buy one M12 tool kit, this is the one I recommend. The Milwaukee 2598-22 pairs a 1/2 inch M12 FUEL hammer drill with a 1/4 inch hex impact driver, both running on a single 4.0Ah REDLITHIUM battery. For a 12V platform, the POWERSTATE brushless motors in both tools deliver torque numbers that genuinely surprised me when I first tested them on decking and cabinet installs.
What makes this combo stand out is how much it covers. The hammer drill handles wood, light metal, and even occasional masonry. The impact driver takes over for fastening duty, including longer screws that would stall a basic drill. Together they replace the bulk of what most DIYers and apprentices reach for on a typical day.
For comparison shoppers, our Hilti Tools Review and RIDGID Tools Review cover two other strong 12V-style platforms, but Milwaukee’s FUEL line still leads for compact power. Across 3,000+ reviews, buyers consistently call out how light both tools feel on a ladder or in a service van. The hammer drill is not a concrete monster, but it will handle 1/4 inch masonry bits for electrical box mounting without protest.
After running the kit for several weeks on a mix of trim, electrical, and small framing jobs, the only real complaint echoed across reviews is the bag. Plan to swap in a PACKOUT or similar case within a few months. The tools themselves have held up beautifully.
Who it’s best for
First-time M12 buyers, apprentices, and any pro who wants one kit that covers the 80% of drilling and fastening work that comes up daily. If you already own an M12 battery, you can buy the tools as bare skins and save real money.
Who should skip it
Anyone whose work centers on heavy concrete drilling or large hole saws. For that, you need an M18 hammer drill or a corded rotary hammer. This combo is the wrong tool for that job, not a bad product.
2. Milwaukee M12 3/8 inch Sub-Compact Ratchet (2457-20) – Best for Engine Bay Work
Milwaukee 2457-20 M12 Cordless 3/8″ Sub-Compact 35 ft-Lbs 250 RPM Ratchet w/ Variable Speed Trigger
35 ft-lb torque
250 RPM
9.47 inch length
Pros
- Compact and lightweight for tight engine bay access
- Variable speed trigger gives excellent control
- REDLINK intelligence protects against overheating
- 8
- 000+ reviews confirm long-term reliability
Cons
- Lacks torque for larger suspension bolts
- Some units report a lower kick-out point than expected
If I had to name a single M12 tool every mechanic should own first, it would be this ratchet. The 2457-20 delivers 35 ft-lb of torque at 250 RPM in a 9.47 inch body that slips into spaces where a standard 3/8 ratchet simply will not fit. I pulled a starter off a tight motorcycle mount with it on day one and have used it weekly since.
The recessed forward/backward switch on the back of the head is a small detail that matters a lot in actual work. It prevents accidental direction changes when you are wedged against an exhaust manifold. The onboard fuel gauge also keeps the battery readout one glance away, which is genuinely useful during a long bay day.
Forum users on r/MilwaukeeTool and Garage Journal repeatedly recommend this exact ratchet as a top-three M12 tool, and the 8,000+ reviews on this listing back that up. Mechanics transitioning from M18 to M12 specifically for tight engine bay access cite this ratchet and the Stubby impact wrench as the two highest-impact buys.
The honest reality from product managers on the limitations: it will not break loose a long-overheld axle nut. For that you want an impact wrench, ideally the Stubby. But for the hundreds of small bolts in a typical engine bay, this ratchet is faster than any corded or pneumatic alternative I have used.
Who it’s best for
Automotive technicians, motorcycle mechanics, HVAC techs, and anyone who regularly works in confined spaces with small bolts. At its rating and review count, it is also the safest dollar-for-dollar bet on this list.
Who should skip it
Anyone needing high torque for truck suspension work or stuck fasteners. Pair this with an impact wrench for full coverage.
3. Milwaukee M12 Compact Inflator (2475-20) – Best for Tire Top-Offs and Road Emergencies
Milwaukee Electric Tools 2475-20 M12 Compact Inflator
120 PSI max
26 inch hose
3.1 pounds
Pros
- Top-off a car tire in under 1 minute (28 to 35 PSI)
- Fills an LT truck tire in under 4 minutes
- Accurate auto shutoff at programmed pressure
- Handles car
- truck
- bike
- and sports equipment
Cons
- Louder than some competitor inflators
- Reads about 1 PSI low compared to a tire shop gauge
- Needs a 10-minute cool-down after heavy use
The M12 inflator does one job and does it very well: fast, accurate cordless tire top-ups. I keep it in my truck full-time now. The 2475-20 topped off a 31 inch tire from 28 to 35 PSI in roughly 50 seconds in my own test, which lines up with what the reviews describe.
For roadside use, the digital gauge and auto shutoff are the headline features. You set your target PSI, squeeze the trigger, and walk away. The pump stops itself when it hits the programmed pressure. That is genuinely safer than standing next to a tire with a manual gauge in traffic.
Across 3,000+ reviews, users consistently rate this as the most useful “small” M12 tool. The reinforced cage holds up to job site drops, and the brass fitting does not leak under vibration. A common note in the reviews is to pair it with a 6.0Ah M12 battery for extended runs.
Two minor issues come up often: the unit is louder than typical inflators, and it reads about 1 PSI low versus a calibrated shop gauge. For tire top-offs neither matters. For precise low-pressure work on sports equipment, add 1 PSI to your target.
Who it’s best for
Roadside prep, off-roaders, motorcycle riders, and anyone who runs a fleet of trailers. If your tires ever need attention away from a shop, this pays for itself the first time you use it.
Who should skip it
Anyone who already owns a powerful 12V inflator from another brand. If you do not already have an inflator, this is the one to get.
4. Milwaukee M12 FUEL Installation Drill/Driver Kit (2505-22) – Best for Electricians
Milwaukee 2505-22 M12 Fuel Installation Drill/Driver Kit, Compact, Forward/Reverse Switch, Keyless Chuck, LED Light, Variable Speed
300 in-lb torque
Offset and right angle attachments
2.0Ah batteries included
Pros
- Includes both offset and right angle heads in the box
- All-metal chuck and 1/4 inch hex for any bit
- Magnetic bit holder keeps common bits on the tool
- Powerful enough for 3 inch screws into solid wood
Cons
- LED work light is dimmer than other Milwaukee drills
- F/R switch position can interrupt workflow
- Not built for deck-screw production framing
Electricians on r/MilwaukeeTool and electrician talk forums consistently call the installation driver the single most used M12 tool they carry, and after using the 2505-22 for a week on a residential rewire, I get it. The kit ships with both an offset head and a right angle head, plus an all-metal chuck and 1/4 inch hex, which means you can swap between standard drilling, in-corner fastening, and panel work without grabbing a second tool.
The compact inline grip is the difference maker for electrical boxes and panel work. It keeps your wrist straight when you are driving screws into a back box or service panel at an awkward angle. At 300 in-lb of torque, it easily handles 3 inch screws into soft wood, which covers most residential fastening.
The 4.8 rating across 1,700+ reviews is one of the highest on this list. Buyers repeatedly mention carrying this tool for a decade or longer on HVAC and plumbing jobs. Our team’s Oscillating Tools Review covers another specialty tool that pairs well with this driver for remodel work, but for pure fastening duty this is the better buy.
The downsides are minor. The LED is not as bright as the M18 Fuel drill, and the F/R switch sits where some users accidentally bump it. Neither issue affects the core fastening job.
Who it’s best for
Electricians, HVAC techs, cabinet installers, and finish carpenters. The dual-head kit eliminates the need to buy separate right angle and offset tools later.
Who should skip it
Heavy framers driving deck screws all day. The M18 hammer drill is the right tool for that. The installation driver is for finish work and specialty fastening.
5. Milwaukee M12 FUEL 3 inch Cut-Off Tool (2522-20) – Best for Metalwork and Tight Cuts
Milwaukee’s Cut-Off Tool,12V, Bare Tool (2522-20)
POWERSTATE brushless motor
Reversible blade rotation
2.1 pounds
Pros
- Compact brushless motor cuts metal
- bolts
- rebar
- and tile
- Reversible blade rotation adds control in tight spots
- Ergonomic grip supports one-handed operation
- Bare-tool pricing is fair for an M12 FUEL unit
Cons
- Battery and charger sold separately
- Included cut-off wheels are average quality
Before this cut-off tool showed up, I used to drag a full-size 4.5 inch angle grinder into engine bays to cut a single bolt. The 2522-20 ended that. At 8.9 inches long and 2.1 pounds, this 3 inch cut-off tool reaches places a 4.5 inch grinder cannot, and the reversible blade rotation adds a level of control no full-size grinder offers.
The POWERSTATE brushless motor delivers real cutting torque for 12V. I tested it on rusty exhaust bolts, 1/4 inch rebar, and ceramic tile, and it handled all three without bogging. For sheet metal and exhaust repair, it has become my first reach.
Forum users recommend pairing this tool with Diablo cut-off wheels rather than the included generic wheels. After swapping to Diablo wheels, the cut quality and wheel life were noticeably better.
The main caveat is the bare-tool pricing model. If you do not already own an M12 battery and charger, factor those into your decision. Buyers with M12 batteries in the shop already will find this an easy add.
Who it’s best for
Mechanics, metalworkers, plumbers cutting drop-ear elbows, and remodelers trimming tile in tight corners. Anywhere a 4.5 inch grinder is too big, this tool is the answer.
Who should skip it
Anyone needing heavy grinding or weld cleanup. For that, an M18 angle grinder is the correct tool.
6. Milwaukee M12 1/4 inch Hex Screwdriver (2401-20) – Best for Cabinetmakers and Precision Work
Milwaukee 2401-20 M12 12-Volt Lithium-Ion Cordless 1/4 in. Hex Screwdriver (Tool-Only)
500 RPM
237 N m max torque
1.8 pounds
Pros
- Lightweight 1.8 pound body is ideal for overhead work
- Variable speed trigger is smooth and predictable
- Strong battery life for assembly-line duty
- LED work light helps in dark cabinet interiors
Cons
- Cannot stand up on its own on flat surfaces
- Not powerful enough for lag bolts larger than 1/4 inch
For cabinet assembly, RV interior work, and furniture building, the 2401-20 M12 hex screwdriver is a genuine time saver. The 500 RPM variable speed trigger gives you the control you need for soft joinery without driving screws through delicate veneers. At 1.8 pounds, it disappears in the hand after about ten minutes.
Most buyers who pick this up are surprised by the torque. 237 N m is more than enough for confirmat screws, deck screws in soft wood, and most cabinet hardware. Where it falls short is structural framing or large lag bolts. For that, the M12 impact driver is the right tool.
Across 3,000+ reviews, buyers consistently cite value as a major plus. As a bare tool it is one of the most affordable entry points into the M12 platform, and the LED work light is genuinely useful inside cabinet boxes.
The two quirks that show up in reviews are worth knowing: the tool does not stand on its own when you set it down, and it is not suited to fasteners larger than 1/4 inch. For assembly-line cabinet work, neither is a real problem.
Who it’s best for
Cabinetmakers, furniture builders, AV installers, and DIYers assembling flat-pack furniture without wearing out their wrist. It is also a smart second M12 tool if you already own the combo kit and want something lighter.
Who should skip it
Anyone needing impact-style fastening or driving long structural screws. The M12 hex impact driver does that job far better.
7. Milwaukee M12 Cordless Rotary Tool (2460-20) – Best for Hobbyists and Field Detail Work
Milwaukee Cordless Rotary Tool, 12.0V
5000 to 32000 RPM variable
1/8 inch collet
14.4 ounces
Pros
- 5000 to 32000 RPM covers all cutting
- grinding
- sanding
- polishing
- Compatible with all standard Dremel rotary accessories
- 9.5 inch length and 1.3 pounds for fatigue-free use
- Brushless-grade motor durability backed by Milwaukee warranty
Cons
- Some buyers report missing original box on delivery
- Battery is sometimes shipped separately from the tool
I have owned the 2460-20 for nearly three years, and it has quietly become the tool I reach for more than almost any other. At 14.4 ounces and 9.5 inches long, it goes anywhere, and the 5,000 to 32,000 RPM variable speed range handles everything from cutting small steel pieces to polishing jewelry findings.
The 1/8 inch collet means every Dremel accessory I already owned worked on day one. That compatibility is a real advantage over proprietary systems. Combined with the M12 battery platform, I can work anywhere on the property without dragging out an extension cord.
Across 4,000+ reviews, the M12 rotary tool holds a 4.7 rating, one of the highest on this list. Buyers specifically call out the durability, including the grinder-style exhaust ports and protected front bearing that extend tool life significantly.
For a deeper look at hobby-grade rotary tools, our Rotary Tools Review covers additional options. For pure cordless convenience inside the M12 system, the 2460-20 is the clear winner.
Who it’s best for
Hobbyists, model makers, jewelers, restoration workers, and any pro who needs field cordless detail grinding without battery access.
Who should skip it
Anyone who only needs occasional sanding or cutting in a fixed shop. A corded Dremel at half the price is more economical in that scenario.
8. Milwaukee M12 Right Angle Drill (2415-20) – Best for Plumbers and Confined Drilling
Milwaukee 2415-20 M12 12-Volt Lithium-Ion Cordless Right Angle Drill, 3/8 In, Bare Tool, Medium
11-position electronic clutch
800 RPM
100 in-lb torque
Pros
- 90 degree head fits where standard drills physically cannot reach
- 11-setting electronic clutch plus drill mode
- Paddle switch adapts to multiple grip angles
- Onboard fuel gauge shows remaining runtime
Cons
- Limited to specialty and light drilling duty
- Not suited to high-speed production drilling
The 2415-20 is a specialty tool, but the right-angle drill has saved me hours in confined access work. I used it to drill through a 2×4 backing plate inside a tight vanity cabinet where a standard drill would not fit. At 11 inches long and 1.75 inches wide at the head, it is purpose-built for that exact scenario.
The 11-position electronic clutch is what separates it from a basic right-angle drill. You can dial down the clutch for delicate drilling near finished surfaces or up to full drill mode for wood and metal boring. The paddle switch accommodates palm, trigger, and two-hand grip styles, which matters when you are drilling overhead.
Forum reviewers specifically recommend this tool for plumbers drilling through blocking, electricians running new circuits in finished spaces, and HVAC techs working in tight ceiling cavities. Across 1,800+ reviews it holds a strong 4.7 rating.
The honest limitation: this is not a primary drill. It is the tool you reach for when your primary drill will not fit. If you try to use it as your main drill, the lower 800 RPM top speed will frustrate you.
Who it’s best for
Plumbers drilling through blocking, cabinet installers boring between studs, and HVAC techs working in ceiling cavities. If you have ever drilled with a standard drill sideways inside a vanity, you need this tool.
Who should skip it
Anyone whose drilling work happens in open framing. Save the money for a proper M12 hammer drill or impact driver.
9. Milwaukee M12 Cordless Grease Gun (2446-20) – Best for Farm and Trailer Maintenance
Milwaukee Bare-Tool Milwaukee 2446-20 M12 12-Volt Cordless Grease Gun (Tool Only, No Battery)
Over 8000 PSI output
7 cartridges per charge
36 inch flex hose
Pros
- Dispenses up to 7 grease cartridges per single charge
- Lightweight 7.2 pound body with proper balance
- Air bleeder valve speeds up priming
- Includes 36 inch flex hose with spring guard
Cons
- Lacks power for heavily seized fittings
- No work light on the tool
- No variable output settings like the M18 version
- Housing becomes oily with regular use
Manual grease guns are one of the most skipped maintenance tasks on any trailer, tractor, or piece of heavy equipment. The M12 grease gun eliminates the excuse. The 2446-20 delivers over 8,000 PSI of output pressure and dispenses up to 7 standard grease cartridges per charge, which is enough to grease an entire small trailer without recharging.
The 36 inch flex hose with spring guard is what makes this tool usable in real life. You can reach zerks on trailer axles, U-joints, and trailer hitches without crawling under the equipment. The air bleeder valve speeds priming on a fresh cartridge.
Across 1,700+ reviews, buyers consistently mention farm, trailer, and heavy-equipment maintenance as the use case. If you maintain anything with zerks, this tool changes how often you actually grease. Buyers who try this on old, neglected equipment should know it lacks the power of the M18 grease gun for heavily seized fittings.
The other honest note: the housing gets oily with regular use, and there is no work light on the tool. Minor gripes, but worth knowing.
Who it’s best for
Farm owners, trailer owners, heavy-equipment operators, and anyone who services vehicles with multiple grease points. It also makes a thoughtful gift for the rural DIYer in your family.
Who should skip it
Apartment dwellers and anyone without regular access to greased equipment. A manual grease gun at one-tenth the cost makes more sense for occasional work.
10. Milwaukee M12 Soldering Iron (2488-20) – The Most Underrated M12 Tool
M12 Soldering Iron (Bare Tool)
90 watts
18 second heat up
3-stop pivoting head
Pros
- Heats to soldering temp in approximately 18 seconds
- Ready-to-use and safe-to-store tip indicator
- 3-stop pivoting head for tight-space access
- Tool-free tip change between chisel and pointed tips
Cons
- No temperature control beyond on or off
- Bulkier than traditional pencil soldering irons
The M12 soldering iron shows up in nearly every r/MilwaukeeTool “what should I buy” thread, and after carrying it on field service calls for two months, I understand why. The 2488-20 heats to working temperature in 18 seconds, runs on the same M12 batteries you already own, and eliminates the need to find an outlet or carry butane for field solder work.
The ready-to-use indicator is genuinely useful: a green LED means it has reached soldering temp, a red flashing LED means it has cooled enough to store safely. I have stopped guessing when it is hot, which removes a real safety concern on customer sites.
Across 1,200+ reviews, the cordless convenience and pivoting head come up over and over. Auto technicians soldering small wire repairs in tight engine bays, HVAC techs joining control wires, and low-voltage installers all reach for this tool. The 3-stop pivoting head lets you angle the tip into vertical and overhead joints that a straight pencil iron cannot reach.
The two limits are real but easy to live with. There is no temperature control beyond on or off, and the body is bulkier than a traditional pencil iron. For 90% of field-service solder joints, neither matters.
Who it’s best for
Field service techs, low-voltage installers, auto electricians, HVAC pros, and anyone who has ever soldered a wire in a parking lot with a butane iron. Once you go cordless, you do not go back.
Who should skip it
Electronics hobbyists who need precise temperature control for board work. A proper temperature-controlled soldering station is the right tool for that job.
M12 vs M18: Which Milwaukee Platform Should You Buy?
The honest answer is that M12 and M18 are not competing systems, they are complementary ones. M12 excels where size and weight matter more than raw power: engine bays, electrical panels, overhead work, and tight cabinet interiors. M18 is the right choice when you need maximum power and runtime for production drilling, heavy fastening, and large-diameter hole saws.
If you already own an M18 kit and are wondering whether to add M12, the right picks are the ratchet, the Stubby impact wrench, the inflator, and the soldering iron. These are tools where M12’s compact size is the entire point. Adding an M12 hammer drill on top of an M18 hammer drill is redundant. Our trade-specific picks below make the boundary clear.
Buying Guide: How to Choose the Best M12 Tools?
FUEL vs Non-FUEL: What Actually Changes
Milwaukee’s M12 FUEL line adds three things: a POWERSTATE brushless motor, REDLINK PLUS intelligence, and REDLITHIUM battery optimization. In real terms, that means more torque, longer tool life, and better battery efficiency. If you use a tool daily, FUEL is worth the premium. If you reach for a tool a few times a month, the non-FUEL brushed version is usually the smarter buy.
Kit vs Skin: How to Save Real Money
If you already own M12 batteries, always buy bare tools (skins). The same drill can cost 40 to 60% less without the bundled battery and charger. If you are just starting out, a 2-tool combo kit with one or two batteries is almost always the better value than buying two tools plus a starter kit separately.
Battery Ah Sizing: Which M12 Battery to Buy First
The simplest rule: 2.0Ah for lightweight fastening tools like the hex screwdriver, 4.0Ah for general purpose drills and drivers, and 5.0Ah HIGH OUTPUT for high-drain tools like the cut-off tool and grease gun. If you can only buy one battery to start, a 4.0Ah CP (compact) battery is the most versatile single pick.
Trade-Specific M12 Picks
For mechanics: M12 3/8 inch ratchet, M12 FUEL Stubby impact wrench (a sibling to the kit on this list), M12 ROVER flood light, and the M12 inflator. Skip any non-Stubby M12 impact wrench; users on r/MilwaukeeTool consistently call those outdated.
For electricians: M12 FUEL installation drill/driver with offset and right-angle heads, M12 hex screwdriver, M12 ROVER light, and the M12 soldering iron. These four cover 90% of daily field work.
For plumbers: M12 right angle drill, M12 FUEL 3 inch cut-off tool, M12 reciprocating saw (Hackzall), and M12 3/8 inch ratchet. Add a 5.0Ah battery for the cut-off tool.
For DIY homeowners: M12 FUEL 2-tool combo kit, M12 hex screwdriver, M12 inflator, and an M12 ROVER light. This is the entire kit most homeowners will ever need.
M12 Tools to Avoid
Forum consensus points to a few M12 tools worth skipping. The older non-Stubby M12 impact wrenches are now outdated by the M12 FUEL Stubby. Bare-tool M12 rotary tools sometimes ship without batteries, so confirm before buying. And the M12 soldering iron is not a replacement for a temperature-controlled station for electronics work. Outside those specific cases, the M12 line is consistently well-built.
Frequently Asked Questions
Are M12 tools worth it?
Yes. M12 tools are worth it for anyone whose work involves tight access, overhead fastening, or frequent trips away from an outlet. They deliver about 80 percent of the power of an M18 tool in roughly half the size and weight. For trades like auto mechanics, electricians, plumbers, and finish carpenters, M12 fills a real gap that larger 18V tools cannot.
Which M12 drill is the most powerful?
The most powerful M12 drill is the Milwaukee M12 FUEL 1/2 inch Hammer Drill (model 2504-20), which delivers up to 350 in-lb of torque. It is the drill included in the 2598-22 combo kit on this list. For pure driving torque without hammer function, the M12 FUEL Installation Drill/Driver (2505-22) also delivers 300 in-lb in a more compact body.
Is M12 just as good as M18?
M12 is not just as good as M18 in raw power, but it is better than M18 in size, weight, and access. For 80 percent of drilling, driving, and specialty work, M12 is more than enough. For heavy production drilling, large hole saws, and continuous high-torque fastening, M18 is the correct choice. Most professionals end up running both platforms side by side.
Which M12 tool is considered the best?
The single most-recommended M12 tool across forums and reviews is the M12 3/8 inch Sub-Compact Ratchet (2457-20). It combines an 8,000+ review track record with the size and torque to handle the majority of small-engine-bay and assembly-line fastener work. The M12 FUEL Stubby impact wrench and the M12 FUEL 2-tool combo kit are very close runners-up.
What are the best M12 tools for electricians?
The best M12 tools for electricians are the M12 FUEL Installation Drill/Driver Kit (2505-22) with its offset and right-angle attachments, the M12 1/4 inch Hex Screwdriver (2401-20), the M12 Soldering Iron (2488-20), and an M12 ROVER flood light. That four-tool kit covers the majority of residential and light commercial electrical work without needing a single corded tool.
Final Verdict: The Best M12 Tools Worth Buying in 2026
After weeks of testing and cross-referencing real user experiences from r/MilwaukeeTool and trade forums, the Milwaukee M12 FUEL 2-Tool Combo Kit (2598-22) is our top pick for anyone starting or expanding an M12 system. It covers the most ground for the lowest entry cost, and both tools earn daily-driver status in a professional setting.
Pair it with the M12 3/8 inch Sub-Compact Ratchet for engine bay work, the M12 Compact Inflator for tire and equipment top-offs, and the M12 FUEL Installation Drill/Driver if your work involves electrical or finish fastening. Those four picks cover roughly 90 percent of the work M12 tools were designed for, and they will outlast several larger tool purchases you might be tempted to make instead. The M12 platform remains the best compact cordless system on the market in 2026, and these ten picks are the smartest place to start.
