Our take on the DeWalt DCF840D1 20V MAX* Brushless Cordless 1/4 in. Impact Driver Kit

The DeWalt DCF840D1 is a 20V MAX brushless 1/4 in. impact driver kit with a battery, charger and belt clip. Its brushless motor delivers up to 1,700 in-lb of torque and 3,200 RPM, and a compact body helps it reach tight spots. A 3-LED light illuminates dim work areas. It suits homeowners and tradespeople who want a light, powerful driver for large screws and deck work; rivals in the same class trade some torque for smaller size or add multi-speed modes.

Questions and answers

Is the DCF840D1 good for deck building?
Yes. Its 1,700 in-lb of torque and 3,200 RPM handle large-diameter screws and lag bolts well. The compact body helps between joists.
Does it come with a battery and charger?
Yes. The kit includes one 20V MAX battery, a charger and a belt clip.
How does it compare with DeWalt's multi-speed drivers?
This model has a single speed range set by the variable-speed trigger. DeWalt's multi-speed drivers add preset modes for finer control on small fasteners.
Is it too big for cabinet work?
It is larger than sub-compact drivers, so tight cabinet interiors can be awkward. For small screws and confined spaces, a sub-compact model fits better.
What battery does it use?
It runs on DeWalt 20V MAX batteries, so it shares packs with other tools in that line.
