Overview
Milwaukee sells the 2457-20 as a bare tool, an M12 12 volt impact driver weighing about 1 lb without a battery or charger included. It is built for one handed control in tight spaces.
Milwaukee's M12 line targets jobs where a full size 18 volt impact driver is too bulky, and this 1 lb weight reflects that positioning.
- 12 volt M12 platform
- About 1 lb bare tool weight
- Sold without battery or charger
Who it's for
Suits owners already invested in Milwaukee's M12 battery platform who want a small impact driver for cabinetry, electrical or trim work. Not a fit for anyone without M12 batteries on hand, since this ships as a bare tool.
Pros and cons
- Compact and light at about 1 lb
- Fits the existing M12 battery platform
- High review volume with a strong average rating
- Bare tool only, no battery or charger included
- Lower torque than full size 18 volt impact drivers
Performance notes
At 12 volts and about 1 lb, the 2457-20 favors control in confined spaces over maximum torque, the tradeoff across Milwaukee's compact M12 lineup. The -20 suffix means it ships without a battery, charger or case.
