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. It carries a 4.6 rating across more than 8,000 reviews with about 3,000 units bought in the past month, a strong repeat purchase signal within Milwaukee's M12 catalog.

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.
Strengths and trade-offs
Drawn from this product's published specifications.
