About this product
The DeWalt DCF921 18V XR Cordless Brushless 1/2in Compact Impact Wrench is designed for demanding fastening work, including scaffolding applications, thanks to a hole in the anvil for securing sockets with a retaining pin or O-ring, plus a hog ring square drive for quick socket changes. Its brushless motor delivers up to 406Nm fastening torque and 610Nm nut-busting torque, with a no-load speed of 2,500rpm and 3,600 impacts per minute.
A tactile 4-mode select feature offers different speed and torque settings, including a precision mode to help prevent over-tightening and run-off. The variable speed trigger gives full control, while an adjustable LED work light with brightness control and delay feature aids visibility in low light.
Compact and lightweight at 1.1kg, it has a rubber XR grip for comfort. Supplied with two 18V 5.0Ah Li-ion batteries, a charger and a TSTAK carry case.
