Our take on the DeWalt DCF840C2 20V MAX* 1/4" Brushless Cordless Impact Driver Kit

The DeWalt DCF840C2 is a 20V MAX cordless impact driver kit built around a brushless motor rated at 1,700 in-lb of torque, 3,200 rpm and 4,200 impacts per minute. It is compact at 5.1 inches long and 1.95 lbs bare, with a 1/4-inch hex drive, a variable-speed trigger and a three-LED work light. The kit adds two 20V MAX batteries, a charger, a belt hook and a kit bag. It suits drivers who want near-flagship torque in a short body without stepping up to DeWalt's premium Atomic or FlexVolt lines.

What reviewers say

  • 4.9 / 514 ratings

Ratings are very high, with owners praising the torque-to-size ratio and the brushless motor. Few complaints surface; the main notes are the lack of speed presets and the light's shadowing up close.

About the DeWalt DCF840C2 20V MAX* 1/4" Brushless Cordless Impact Driver Kit

This is a 20V MAX* cordless impact driver kit with a 1/4" hex drive. It is built to drive screws and other fasteners, including large-diameter screws. The tool is lightweight and compact.

A brushless motor delivers up to 1,700 in-lb of torque and up to 3,200 rpm. A variable speed trigger gives control over the tool's speed. The compact design helps with access to confined and hard-to-reach spots, such as in cabinetry and framing jobs.

An integrated 3-LED work light illuminates dark or dimly lit work areas.

Questions and answers

How does the DCF840C2 compare with the DCF845?
The DCF845 is the newer driver with a similar 1,700 in-lb rating and a four-speed mode selector. The DCF840C2 relies on a variable trigger only, so pick the 845 if you want preset speeds.
Is it powerful enough for lag screws and decking?
Yes. At 1,700 in-lb it drives long lag screws and structural fasteners that smaller 1,400 in-lb drivers struggle with.
What comes in the kit?
The driver, two 20V MAX batteries, a charger, a belt hook and a kit bag.
Does it use the same batteries as other DeWalt 20V MAX tools?
Yes. It runs on any DeWalt 20V MAX battery, so it shares packs with the rest of the platform.
How heavy is it in use?
The bare tool is 1.95 lbs; with a battery mounted it is heavier but still balanced for overhead work.
Does it have a bit holder or quick-release chuck?
It has a 1/4-inch hex quick-release chuck that takes standard impact-rated bits.
Where is the DeWalt DCF840C2 20V MAX* 1/4" Brushless Cordless Impact Driver Kit cheapest?
At Authorized Tool Outlet, for $159.00, as of our latest check.
