The DeWalt DCF921 is a 20V Max brushless 1/2-inch impact wrench rated at 450 Nm of max torque. It is a bare tool, so batteries and charger are sold separately, and it is built for lug nuts, suspension bolts and heavy assembly work. The brushless motor and compact body put it against mid-torque cordless wrenches from Milwaukee and Makita, which offer similar torque in a slightly different package. Owners rate it highly for power in a small frame, though some note the bare-tool format adds cost if you are not already on the 20V platform.
