The main trade-off
Battery-system continuity versus the value you place on Auto-Load and wrench-free accessory changes.
Quick verdict
Choose the 2836-20 if you already use M18 or specifically want Auto-Load and wrench-free accessory changes. Choose the 2426-20 if keeping your M12 setup matters more and you are comfortable using a hex wrench for changes. With neither system, budget for the matching battery and compatible charger before comparing value.
Choose Milwaukee 2836-20 M18 FUEL Oscillating Multi-Tool (Bare Tool) if
- You want the documented Auto-Load option and lever-and-bolt accessory routine.
Choose Milwaukee 2426-20 M12 Multi-Tool (Bare Tool) if
- You have M12 power equipment and do not mind the documented hex-wrench procedure.
When the recommendation changes
- You have neither battery system: compare complete ready-to-work purchases, not bare-tool prices alone.
- You already own both systems: accessory handling and control become the deciding questions.
The differences that matter
| Decision point | Milwaukee 2836-20 M18 FUEL Oscillating Multi-Tool (Bare Tool) | Milwaukee 2426-20 M12 Multi-Tool (Bare Tool) |
|---|---|---|
| Battery Platform And Startup Requirements | 2836-20 uses M18 batteries; the manual specifies an M18 charger type. The battery is not included.[1, 3] | 2426-20 uses M12 batteries; the manual specifies an M12 charger type. The battery is sold separately.[2, 4] |
What this changes: Start with your battery inventory. Owning the matching pack and a charger approved for it avoids buying another power system; owning only the other platform does not make either bare tool ready to use.[1, 3, 2, 4] The better fit depends on your priorities | ||
| Auto Load And Accessory Change Workflow | A 10-setting dial plus Auto-Load, which increases speed under load. Accessory changes use a quick-release lever and a hand-tightened bolt.[1, 3] | The manual describes setting the maximum speed with the dial and removing/tightening the accessory bolt with a 5 mm hex wrench.[2, 4] |
What this changes: Choose the 2836-20 for its documented Auto-Load option and wrench-free changes. Choose the 2426-20 if its dial-and-wrench routine suits you. Neither procedure removes the need to disconnect the battery, clean mating parts and check accessory fit.[1, 3, 2, 4] The better fit depends on your priorities | ||

Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Compare the tool plus any missing battery, compatible charger, job-specific accessories and adapters. A bare-tool price gap can understate the cost of entering another platform.
There is not enough verified price history here for a purchase-timing recommendation.
Limitations
- This comparison uses the US 2836-20 and 2426-20 bare tools. Confirm the seller’s exact included contents; kit photographs are not a packing list. The 2836-20 accessory pack was not established by the opened product-page text.
- Use only the battery and charger combination approved in their manuals. M12 and M18 tool batteries are different systems. The tool’s DC voltage does not establish a charger’s AC input or suitability for travel.
- No hands-on comparison establishes cutting speed, vibration, runtime or longevity here. Neither voltage, a FUEL label nor an oscillation-rate specification proves a measured advantage.
- For either tool, remove the battery before changing accessories and use only recommended accessories. Secure the workpiece and check for concealed wires and pipes before blind or plunge cuts. Wear the eye protection specified by the manual and appropriate respiratory protection or use an OSHA-compliant dust-extraction solution in dusty work. Remove nail and screw heads before scraping.
Questions shoppers ask
Can I reuse all my existing oscillating-tool blades?
Do not assume universal fit. Match each blade’s arbor to the relevant manual’s chart and obtain an adapter where required. The 2426-20 page lists a wood blade, sanding pad and five sheets; that does not cover every intended material.
Does Auto-Load guarantee a more accurate cut?
No comparative accuracy result is established here. Milwaukee documents a setting that starts slower and increases speed under load; treat that as a control choice, while following the manual’s workpiece, pressure and accessory instructions.
