Milwaukee Rotary Tool: The M12 2460-20 (and the Best Alternatives)
Milwaukee makes exactly one rotary tool: the M12 2460-20. There is no M18 rotary tool and no Fuel-branded rotary tool, despite what a lot of listings imply. Here is what the 2460-20 actually is, when it is the right buy, and which rotary tools to look at if you are not already on the M12 battery platform.
Quick answer
The Milwaukee M12 Rotary Tool 2460-20 is the only rotary tool Milwaukee sells. It is a 12V, brushed, variable-speed tool running 5,000 to 32,000 RPM with a standard 1/8 in. collet, and it makes the most sense if you already own M12 batteries. If you do not, the 2460-21 kit adds a battery and charger, and Dremel's cordless 8250 or corded 4300 are the stronger buys on raw capability.

Milwaukee M12 Rotary Tool (2460-20)
Best for M12 ownersPros
- Variable-speed dial rather than trigger-only control
- Slim inline body that handles like a corded rotary tool
- Runs on the same M12 packs as the rest of the 12V line
Cons
- Battery and charger sold separately
- Brushed motor, and there is no Fuel upgrade to move up to
- Tops out at 32,000 RPM, below most Dremel models
The 2460-20 is Milwaukee's rotary tool, full stop. It is a 12V brushed tool with a variable-speed dial that spans 5,000 to 32,000 RPM, and it takes a standard 1/8 in. collet, so ordinary rotary accessories fit it. Milwaukee does not build a brushless or Fuel version of this tool, and it does not build an M18 one either, so if a listing offers you an "M18 Fuel rotary tool" you are looking at a different tool type wearing the wrong name.
Where it earns its place is the battery. If your shop already runs on M12, this drops into the same charger rotation as your drill and impact driver, and the tool-only price is the whole cost. For cutting drywall openings, deburring, light grinding, and engraving on soft materials, it does the job with better speed control than a trigger-only tool. For long grinding sessions, a 12V pack is the limiting factor, and a corded rotary tool will out-last it.
Milwaukee M12 Rotary Tool Kit (2460-21)
Best Milwaukee starting pointPros
- Same tool, but usable straight out of the box
- The battery and charger carry over to any other M12 tool
- Usually bundled with a case and a starter accessory set
Cons
- Costs meaningfully more than the bare tool
- Pointless if you already own M12 packs
- Bundled accessories are basic and get used up quickly
The 2460-21 is the 2460-20 with an M12 REDLITHIUM battery and charger added, and it is the version to buy if this would be your first M12 tool. Kit contents vary a little between retailers and production runs, so read the listing for what is actually in the box rather than assuming a particular accessory count.
Treat the included accessories as a sampler. Cut-off wheels and sanding bands are consumables, and a separate accessory kit with the abrasives and bits you actually use will cost less than replacing them piecemeal. The battery is the part with lasting value here, since it powers every other M12 tool you buy later.
Dremel 8250 Cordless Rotary Tool
Best cordless alternativePros
- Brushless motor, which Milwaukee does not offer here
- Higher top speed at 35,000 RPM
- Full Dremel accessory and attachment range fits directly
Cons
- Its battery does not share with your other cordless tools
- Costs more than the bare Milwaukee
If you are choosing a rotary tool on merit rather than on which batteries you own, the 8250 is the cordless one to look at. It is Dremel's brushless 12V model, it runs to 35,000 RPM, and the entire Dremel attachment catalogue, including the flex shaft and plunge router base, is built around this body shape.
The trade-off is a battery platform that does nothing else in your shop. That is exactly the calculation to make against the Milwaukee: one more charger and one more pack type, in exchange for a better rotary tool.
Dremel 4300 Corded Rotary Tool
Best for long sessionsPros
- No runtime limit, which is the cordless weak point
- Most powerful of the mainstream rotary tools here
- Many kits include the universal three-jaw chuck
Cons
- Cord gets in the way on ladders and in cabinets
- Heavier in the hand than the M12
Sustained grinding, rust removal, and sharpening are where cordless rotary tools run out of battery and corded ones simply keep going. The 4300 is a 1.6 amp corded tool running 5,000 to 35,000 RPM, and it is the one to own if your rotary work happens at a bench rather than up a ladder.
It also takes every Dremel attachment, so it grows into a small shaping and routing system rather than staying a one-job tool. The cord is the only real complaint, and for bench work it is not much of one.
Dremel 3000 Corded Rotary Tool
Best budget optionPros
- Cheapest honest way into rotary tools
- Same 1/8 in. accessories as everything else here
- Light and easy to control for detail work
Cons
- Less power than the 4300 under load
- Fewer attachment options in the base kit
For occasional jobs, the 3000 is enough tool. It is a 1.2 amp corded model with variable speed up to 32,000 RPM, which matches the Milwaukee's top speed for a fraction of the outlay once you account for a battery and charger.
It bogs down sooner than the 4300 on hard grinding, and the base kits are thinner on attachments. For cutting bolts flush, sharpening blades, and light engraving a few times a year, none of that will matter.
Milwaukee model numbers that are not rotary tools
This is where most of the confusion around a "Milwaukee rotary tool" comes from, because several M12 and M18 model numbers get listed and described as rotary tools when they are not. The 2426-20 is the M12 oscillating Multi-Tool, rated in oscillations per minute rather than RPM. The 2626-20 is the M18 version of that same oscillating multi-tool. The 2625-20 is the M18 HACKZALL, a one-handed reciprocating saw. None of the three accepts a 1/8 in. rotary collet or does anything a rotary tool does.
The practical test before you buy: a rotary tool spins a small accessory in a collet and is rated in RPM. An oscillating multi-tool vibrates a flat blade through a narrow arc and is rated in OPM. If a listing quotes OPM, it is not a rotary tool, whatever the title says.
What to check before buying a Milwaukee rotary tool
Start with the battery platform, because that is the only strong argument for the 2460-20 over its rivals. If you already own M12 packs, the bare tool is cheap to add and shares your charger. If you do not, you are buying into a platform for one tool, and at that point the Dremel models compete on equal footing.
Then check speed control and collet size. A variable-speed dial holds a set speed better than a trigger for engraving and polishing, and the 2460-20 has one. All the tools here use a standard 1/8 in. collet, so accessories move between brands freely, including Dremel-branded bits in the Milwaukee. Some kits add a 1/32 in. collet or a chuck for smaller and odd-sized shanks.
Mistakes to avoid
The biggest one is buying by model number from a listing title. Check the stated speed rating and the collet before you order, since that is what separates a rotary tool from an oscillating multi-tool sold under a similar name.
The second is forgetting the batteries. A bare tool plus a battery and charger usually costs more than the kit, so if you have no M12 packs the kit is the cheaper route. The third is pushing a rotary tool past its job. Cutting thick steel or grinding for long stretches with a 12V tool overheats accessories and drains packs fast. That work belongs to an angle grinder or a corded rotary tool.
FAQs
How many rotary tools does Milwaukee make?
One. The M12 2460-20, sold bare or as the 2460-21 kit with a battery and charger.
Is there an M12 Fuel or M18 Fuel rotary tool?
No. Milwaukee has never made a brushless Fuel rotary tool, and there is no M18 rotary tool at all.
Is the Milwaukee 2426-20 a rotary tool?
No, it is the M12 oscillating Multi-Tool, rated in OPM. The 2626-20 is the M18 multi-tool and the 2625-20 is the M18 HACKZALL reciprocating saw.
Can I use M18 batteries on the M12 rotary tool?
No. M12 and M18 packs use different voltages and different stem designs, and they are not cross-compatible.
Can I use Dremel accessories with the Milwaukee rotary tool?
Yes. Any accessory with a standard 1/8 in. shank fits, and that covers most of the Dremel range.
What is the top speed of the Milwaukee rotary tool?
32,000 RPM, with a variable-speed dial that goes down to 5,000 RPM. Dremel's 8250 and 4300 both reach 35,000 RPM.
How long does an M12 battery last in it?
It depends heavily on the accessory and how hard you lean on it. Light engraving stretches much further than continuous grinding, and a higher-capacity pack is the simple fix if you keep running out.
Is the Milwaukee rotary tool good for engraving?
Yes. The variable-speed dial lets you hold a low, steady speed, which is what engraving on soft metals and plastics needs.
What does the 2460-21 kit include?
The tool plus an M12 battery and charger, normally with a case and a small accessory set. Exact contents vary by retailer, so check the listing.
What warranty does Milwaukee give on it?
Milwaukee's standard five-year tool warranty applies to the rotary tool. REDLITHIUM batteries are covered separately for a shorter period, so check the pack.
Our verdict
If you already own M12 batteries, the Milwaukee M12 Rotary Tool 2460-20 is an easy and inexpensive add to the kit, and the 2460-21 is the version to buy if you are starting from nothing. If you are choosing purely on the tool, Dremel's brushless 8250 or corded 4300 are stronger, and the 3000 covers occasional use for much less. What you should not do is buy a 2426-20, 2626-20 or 2625-20 expecting a rotary tool, because those are multi-tools and a reciprocating saw.
