Our take on the Milwaukee 3651-20 18V Compact Cordless 1/4″ Hex Impact Driver

The Milwaukee 3651-20 is a compact 18V impact driver built for tight spaces: 4.4 inches long and 1.7 lb bare. It delivers up to 1,700 in-lb of torque, 3,600 RPM and 4,900 IPM from a brushless motor, with three drive modes for precision work. An all-metal gear case and integrated LED round out the package. It suits pros and serious DIYers already on the Milwaukee 18V platform; rivals like the DeWalt DCF887 are similarly compact, so the choice often comes down to which battery system you own.

Questions and answers

Is the Milwaukee 3651-20 good for tight spaces?
Yes. At 4.4 inches long it is one of the shorter 18V impact drivers, so it fits between studs and inside cabinets where full-size drivers struggle.
Does it come with a battery?
No. It is tool-only and runs on any Milwaukee 18V lithium-ion battery, which you buy separately.
How does it compare with the Milwaukee M18 Fuel impact driver?
The 3651-20 is the compact, lower-torque option at 1,700 in-lb. The Fuel model adds more torque and a four-mode drive but is larger and heavier.
What can it drive?
It handles wood screws, metal fasteners and concrete anchors. The three-mode control lets you dial back speed for small screws and trim work.
Does it have a brushless motor?
Yes. The brushless motor runs cooler and lasts longer than brushed motors, and it helps get the most runtime from each battery charge.
Where is the Milwaukee 3651-20 18V Compact Cordless 1/4″ Hex Impact Driver cheapest?
At Mass Depot, for $84.99, as of our latest check.
