Performance
Physical & Build
The DCF850 is DeWalt's ATOMIC compact impact driver, packing the same 205Nm and 3-speed Precision Drive as the DCF887 into a much shorter 100mm body. That stubby head reaches into joists, cabinets and tight corners the full-size driver cannot. We rate it the pick for XR owners who value access and control; the DCF887 is the slightly longer standard alternative, and the 282Nm DCF860 is there if you need maximum torque.
