Overview

1,000 units bought in the past month makes the DEWALT DCF860B one of the stronger sellers here, running a 20 volt, 5 amp system up to 3800 RPM at 2.8 pounds. It carries a 4.7 rating across 980 reviews.

3800 RPM and a sub-3 pound body are typical of a compact impact driver built for fast fastening rather than heavy drilling. The B suffix on DeWalt model numbers commonly marks a bare tool listing, sold without battery or charger, so buyers should confirm what is included before ordering rather than assuming a full kit.

Who it's for

The DeWalt 20V battery platform is the natural home for this impact driver, for anyone already holding batteries from that line. Starting from scratch without existing DeWalt batteries is less ideal, if this turns out to be a bare tool listing as the model suffix suggests.
