Does the DCF900B come with a battery and charger?

No. It is sold as a bare tool, so you need a DeWalt 20V MAX battery and charger separately.

What is Precision Wrench mode?

It is a control mode that limits overtightening in forward and fastener run-off in reverse for more repeatable results.

Will it remove semi-truck lug nuts?

Its breakaway torque handles most heavy lug and structural fasteners, but the largest truck hardware may need a higher-output battery.

Which batteries fit it?

It uses DeWalt 20V MAX batteries; high-capacity XR packs give the best performance on heavy fastening.

About the DeWALT DCF900B 20 Volt, Pistol Grip Cordless Impact Wrench

The DEWALT DCF900B is a 20V MAX XR cordless impact wrench with a 1/2 in drive and a pistol grip. It delivers 1,030 ft-lbs of max fastening torque and 1,400 ft-lbs of max breakaway torque. That output suits heavy-duty work such as large pipe flanges, grooved couplings, wheel lugs, concrete anchor bolts and structural fasteners.

A 4-mode push-button selector adjusts speed and torque output, and it also controls LED brightness. Precision Wrench control mode helps prevent overtightening when driving forward and fastener run-off in reverse. An on-tool LED work light improves visibility when working under vehicles, inside mechanical rooms or in low light.

BATTERYGUARD technology is a shock-absorbing battery-to-tool connection that helps reduce wear during heavy use. The tool is part of the DEWALT 20V MAX XR system.
