The DEWALT DCF921 18v XR Cordless Brushless 1/2" Compact Impact Wrench features an efficient brushless motor that delivers increased power, durability and efficiency. With the new brushless motor and new optimized mechanism this delivers an incredible 409Nm fastening torque and 610Nm of breakaway torque. It also features an adjustable LED light with brightness control for improved visibility and functionality. This impact wrench has a tactile 4 mode select feature. This allows the user to select different modes and speed settings for ultimate control. The scaffold mode helps to prevent overtightening in forward and fastener run-off in reverse.

Scaffolding Mode

This tool is equipped with a mode designed for scaffolding applications. In forwards rotation it will run down the nut on the scaffold clamp and then impact for a period of time before cutting off to avoid over tightening of the fastener. In reverse rotation it will impact to break the nut free, before winding down the nut and cutting off after a period of time to limit damage to clamps

Precision Wrench

In addition to low speed impacting modes, this tool features the Precision Wrench mode which grants the user greater control in both fastening and loosening applications. When set in forward, the tool will fasten at 2500 RPM until impact begins. The tool will then pause for 0.5 seconds before continuing to impact at a rate of 3550 IPM, providing the user with greater control and reducing the chance of overtightening or damaging material. When set in reverse, the tool will impact at a normal speed and rate of 3550 IPM. Upon sensing that the fastener has broken free, the tool will cease to impact and will reduce speed to help prevent run-off of loose hardware.
