DEWALT DCF860B: problems, parts and running costs

Checked: 2026-10-17

Summary

The DCF860B is DEWALT’s highest-torque 20V MAX XR impact driver at 2,500 in-lbs, but that figure is breakaway torque: one owner measured 143 ft-lbs of working torque against the 208 ft-lbs headline, and several owners report that speeds 2 and 3 go unused. Running costs are a 20V MAX battery and charger if you do not already own them (reported $59-$199 for a pack) plus driver bits; there are no consumables. It is a strong buy at $150 or less and weak above $220.

Common problems and fixes

Too much power for precision work — one owner returned or exchanged the tool as “too much power with no precision”; speed 1 is the light-duty setting for cabinet and machine screws. [10]
Speeds 2 and 3 go unused — a long-term owner reports almost never using the 2nd and 3rd modes, so the top-end capability is often wasted. [10]
3-month failure — one Reddit thread reports a unit failing at 3 months (29 upvotes, 98 comments); it is a single unverified report, and a defect would fall under the 3-year limited warranty. [9]
Forward/reverse button feels flimsy — one owner found it “a little flimsy” but clicking into place; another owner confirmed this is normal. [8]
Battery connector play — normal per owners, designed to absorb vibration. [8]
Value against Milwaukee at $199-$219 — at this price the Milwaukee M18 Fuel 2953 bare tool is $149 with a 5-year warranty and faster driving in head-to-head tests. [5]

Parts and consumables

20V MAX XR battery (1.7-8.0Ah) — sold separately; reported at $59-$199 depending on capacity if you do not already own packs. [7]
20V MAX charger — sold separately; no battery or charger is in the box. [1]
Impact driver bits — consumable, not included with the bare tool. [1]
Belt hook — included with the tool. [1]

Yearly running cost

Not enough data to compute a yearly figure. There is no subscription and no consumables; a 20V MAX battery is a one-off $59-$199 purchase if you do not already own packs, plus a charger and driver bits. The sources do not report electricity costs or annual bit spend.

When it is a good buy

The bare tool is listed at $199 at Northern Tool, MaxTool and Acme Tools, and Pro Tool Reviews listed it at $199.99 in November 2024 and $219 in July 2025. A June 2025 Lowe’s promo offered the tool as a free add-on with a 5Ah charger and 2x 5Ah batteries, an effective $81.25 after returning other promo items. [4][5][7][11][12][13][17]

$150 or less — strong value for DEWALT 20V battery owners who need maximum torque; the working-torque gap and the 3-year warranty are acceptable tradeoffs at this price. [4][5]
$151-$199 — fair to good; compare with the Milwaukee 2953 bare at $149 with a 5-year warranty. [5]
$200-$219 — weak for a bare tool; Pro Tool Reviews listed it at $219 in July 2025. [5]
Above $220 — weak against flagship drivers from Milwaukee, Makita and Flex. [5]

Named alternatives:

Milwaukee M18 Fuel 2953 — 2,000 in-lbs, $149 bare, 5-year warranty, faster in all three driving tests; better when speed, warranty length, or lower cost matter. [5]
Flex 24V FX1371A — 2,500 in-lbs (matches the DCF860) and a 4,000 RPM top speed; better if top speed matters more than torque. [4]
