The Milwaukee 2426-21 is a 12V cordless oscillating multi-tool that cuts, grinds, sands and scrapes. Its variable speed runs from 5,000 to 20,000 OPM, so you can slow it down for grout and plastics and open it up for wood. It is small and light enough for one-handed work in tight spots, and it shares the M12 battery system with more than 25 other tools. Compared with 18V multi-tools it gives up some power and speed under heavy load, but it is easier to control overhead and in cabinets. Reviewers like the compact body and the included accessory adapter that takes other brands' blades.

Owners praise the compact size, smooth speed control and the adapter that lets them use blades they already own. Most criticism centers on run time and power when cutting hard material for long stretches.
The Milwaukee 2426-21 is a 12V cordless oscillating multi-tool in the M12 system. It runs at 5,000 to 20,000 OPM, so the speed can be matched to the job. It handles flush or plunge cuts, removing grout or grinding thinset, sanding and scraping.
A variable speed dial offers 12 settings, and an on-board fuel gauge shows the remaining run time. The gear case is all metal. An included universal adapter lets the tool work with most competitive accessories.
The kit comes with one M12 REDLITHIUM battery, which extends run time. The tool is compatible with the M12 lithium-ion system of over 25 cordless tools.
