DeWalt DCF860B 20V MAX XR: What to Know
DeWalt rates the DCF860B at 2,500 in-lbs of maximum fastening torque with a top speed of 3,800 RPM across 3 selectable speed modes, the highest torque figure of any tool in this comparison, 500 in-lbs ahead of Milwaukee's 2953-20 and 900 in-lbs ahead of the Makita XDT16Z. Pro Tool Reviews' independent fastener tests support that headline number in practice: in their testing the DCF860B sank 8-inch GRK RSS structural screws in an average of 7.17 seconds and drove 3/8 x 8-inch lag bolts in just over 6 seconds, edging out both Milwaukee's 2953 and a comparable Flex model in the same test session.
The ASIN verified (B0D45VX1FG) is explicitly labeled "Bare Tool Only" in its Amazon title, and DeWalt's retailer listings confirm it ships without a battery or charger. This is the same bare-tool trade-off buyers run into across nearly every pro-grade impact driver on the market: the DCF860B is sold this way specifically so tradespeople who already own 20V MAX batteries aren't forced to pay for redundant packs, but it does mean a first-time buyer needs to budget separately for at least one 20V MAX battery and a charger before the tool is usable out of the box.
The DCF860B runs exclusively on DeWalt's 20V MAX battery system. Despite the "20V" branding, this is DeWalt's own proprietary platform (nominal battery voltage is actually 18V, similar to competitors' 18V-class systems under different marketing names), it is not interchangeable with Milwaukee M18, Makita 18V LXT, Bosch 18V, or Ryobi 18V ONE+ batteries. DeWalt also markets a brushless motor and TOOL CONNECT Chip readiness for asset tracking via its Site Manager app, an optional feature that has no bearing on driving performance.
