Our take on the DeWalt DCF903B 12V MAX* 3/8" Impact Wrench, Bare Tool

The DeWalt DCF903B is a compact 12V MAX cordless impact wrench with a 3/8-inch square drive, sold as a bare tool without battery or charger. It delivers up to 250 ft-lbs of tightening torque and 400 ft-lbs of breakaway torque, which is high for a 12V tool and enough for most lug nuts and suspension work. Its small body reaches into tight engine bays and wheel wells where larger 18V or 20V wrenches won't fit. The glass-filled nylon housing resists automotive chemicals, and an LED ring lights the work area. It suits mechanics and DIYers already on DeWalt's 12V MAX battery platform who want a light, maneuverable wrench for light-to-medium automotive jobs.

Questions and answers

Does the DCF903B come with a battery and charger?
No. It is a bare tool, so battery and charger are sold separately. You need DeWalt 12V MAX batteries to run it.
Is 400 ft-lbs of breakaway torque enough for lug nuts?
For most passenger cars and light SUVs it is. Check your vehicle's lug nut torque spec; some trucks and heavy-duty vehicles call for more than this wrench's 250 ft-lbs tightening torque.
What drive size does it use?
It has a 3/8-inch square drive, so it takes standard 3/8-inch impact sockets. Use impact-rated sockets, not chrome hand sockets.
How does it compare with DeWalt's 20V impact wrenches?
The 12V MAX is smaller and lighter and reaches tighter spots, but 20V models deliver more torque and longer runtime. The 12V suits light automotive work; the 20V suits heavy fasteners.
Does it have a light?
Yes, an LED light ring around the anvil illuminates the work area in low light.
What is the housing made of?
Glass-filled nylon, which DeWalt says resists harsh automotive chemicals and solvents.
Where is the DeWalt DCF903B 12V MAX* 3/8" Impact Wrench, Bare Tool cheapest?
