Milwaukee M12 FUEL 2526-20: problems, parts and running costs
Checked: 2026-10-10
Summary
The 2526-20 is a 12V brushless oscillating multi-tool sold tool-only: no battery or charger in the box, so the real cost depends on M12 packs you already own. Documented issues are usage cautions from the manual (dull blades binding and kicking back) and wear parts the warranty excludes; no owner failure reports were accessible in research. At $159 bare from Burns Power Tools (October 2026) it is a good buy mainly for existing M12 owners.
Common problems and fixes
- Dull or damaged blades binding and kicking back — the manual warns that dull or damaged blades can cause excessive friction, blade binding and kickback; the fix is to use only sharp blades. Not a defect claim; no owner failure rate exists. [5]
- Tool kicks back when blades hit nail or screw heads — the manual warns that hitting nail or screw heads may kick the tool back; the fix is to keep blades sharp and watch for fasteners in the cut line. [5]
- Wear parts are not covered by warranty — the 5-year tool warranty excludes normal-wear parts including blade clamps, o-rings, seals and bumpers, so those replacements come out of pocket. [2][5]

When it is a good buy
- Bare tool: $159.00 at Burns Power Tools, checked 2026-10-10; Pro Tool Reviews listed the bare tool at $149 and a 4.0Ah kit at $219 in its 2020 review. [3][8]
- For existing M12 battery owners, $159 bare is the logical entry point and the effective cost is lowest. [3]
- For buyers without M12 batteries, the true cost is $159 plus a pack and charger, which puts the total against 18V tools Pro Tool Reviews measured cutting faster in most materials. [4]
- Skil OS592702 (12V kit with battery and charger, $99 per Pro Tool Reviews’ February 2026 prices): the better choice when you want a complete 12V setup at the lowest total cost. [4]
- Ridgid R86242 ($149 bare per Pro Tool Reviews’ February 2026 prices): the better choice when you want Pro Tool Reviews’ best-overall 18V tool for less than the Milwaukee’s bare price. [4]
