Milwaukee 2460-20 vs Dremel 4300-5/40: Check Your Power and Accessories
Choose the Milwaukee 2460-20 when cordless placement matters and you already have, or plan to obtain, suitable M12 power equipment; its battery is sold separately. Choose the Dremel 4300-5/40 when mains power fits your workspace and you want to avoid that battery prerequisite. Then check your intended approved accessories: the Dremel’s adjustable chuck is useful for mixed shank sizes, but some included attachments require a collet.

The buying question
Do you have the M12 power equipment needed for the Milwaukee, and which supplied holder fits your intended approved accessory set?
Milwaukee offers cordless placement with a separate battery prerequisite; Dremel offers mains power and a supplied multi-size chuck with attachment exceptions.
Quick verdict
Choose Milwaukee M12 Rotary Tool 2460-20 if
- You can supply compatible M12 power equipment and want to work without a cord at the tool.
Choose Dremel 4300-5/40 Rotary Tool Kit if
- Your work area has suitable mains power and you prefer not to add an M12 battery setup.
- Your approved accessories use mixed shank sizes within the chuck’s range, with attachments that permit the chuck.
When the recommendation changes
- You must buy M12 power equipment rather than reuse it.
- Your intended Dremel attachment requires a collet, removing the chuck convenience for that task.
The differences that matter
Power Setup
Milwaukee M12 Rotary Tool 2460-20
M12 removable-battery tool. Battery is sold separately; ensure you have a suitable M12 battery and compatible charger.[1, 2]
Dremel 4300-5/40 Rotary Tool Kit
Corded 120V tool: plan for a suitable outlet and the cord at your work area.[3]
What this changes: Check the power equipment you already own before comparing offers. An equipped M12 owner can prioritize cordless placement; a buyer starting without that equipment must account for it. The Dremel avoids a tool-battery purchase but keeps you tied to a mains connection.[1, 2, 3]
Supplied Holder
What this changes: List the approved accessories and attachments you actually intend to use. A suitable all-1/8-inch set gives little reason to choose a multi-size chuck by itself. Mixed suitable shank sizes favor the Dremel’s supplied chuck only where the attachment permits it. Shank fit alone does not establish tool or cross-brand attachment compatibility.[1, 2, 3, 4]
Best for your routine
Existing M12 owner with suitable 1/8-inch accessories and a reason to avoid a cord
Best fit: Milwaukee M12 Rotary Tool 2460-20
Based on listed features, not comparative testing.
The Milwaukee matches that power setup and supplied collet; budget for charging access and verify each accessory’s approval for the tool.
Outlet-based buyer starting without M12 equipment
Best fit: Dremel 4300-5/40 Rotary Tool Kit
Based on listed features, not comparative testing.
The Dremel removes the need to obtain tool-battery equipment. Its cord remains part of the workspace plan.
Buyer alternating approved small-shank accessories at an outlet
Best fit: Dremel 4300-5/40 Rotary Tool Kit
Based on listed features, not comparative testing.
The supplied Dremel chuck covers a range of shank sizes without choosing a separate collet for each size, provided the intended attachment allows that chuck.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Compare a usable setup rather than tool prices alone: count any M12 power equipment you still need and any approved holders or accessories missing for your projects. Reusing owned equipment changes that calculation without proving either option cheaper.
Verified price history is unavailable for this comparison; there is insufficient evidence for purchase timing advice.
Limitations
- This is a power-setup and supplied-holder comparison, not a test of cutting performance, runtime, durability or safety.
- Milwaukee’s product page and linked manual disagree about speed specifications. If accessory selection depends on speed rating or operating limits, verify the actual tool nameplate and applicable supplied manual, or obtain manufacturer confirmation. No numerical speed or accessory-rating threshold is recommended here.
- Charger carton contents and the Dremel storage container are not confirmed here.
Questions shoppers ask
Does tool-only mean the Milwaukee has no cutting accessories?
No. Milwaukee lists five cutting wheels, a mandrel and a wrench with the 2460-20, as well as its supplied 1/8-inch collet. That does not remove the separate battery prerequisite or guarantee the included pieces suit your planned work.
Can I choose either tool just because my bit’s shank fits?
No. Confirm the exact accessory, attachment and intended application are approved for that tool. For example, Dremel’s 565 cutting attachment and A576 guide require a collet even though the 4300 kit supplies an adjustable chuck. Do not infer cross-brand attachment compatibility from diameter alone.
