The DeWalt DCF921N-XJ 18v Brushless 1/2" Compact Impact Wrench delivers up to 609 Nm of breakaway torque (406 Nm of fastening torque), ensuring the removal of the tightest bolts. It features an ultra-compact, lightweight design for use in confined areas. The square drive with hog ring allows for quick socket changes, and the hole in the anvil facilitates securing sockets with a retaining pin or rubber O-ring, making it ideal for scaffolders. The variable trigger provides complete control over all applications. Its efficient brushless motor ensures high performance, extends tool life, and allows for a shorter design (only 125mm). A bright white LED with a delay feature and brightness control improves visibility and functionality in various environments. The comfortable rubber XR grip and switch enhance application comfort and control. The DCF921 is specifically recommended for scaffolding applications. It includes a Scaffolding Mode to prevent overtightening in forward and fastener run-off in reverse. In forward, the tool impacts for 1.5 seconds after run-down to help prevent over-tightening. In reverse, the tool stops when a fastener is loose to prevent run-off. The tactile 4-mode select feature allows users to choose different modes and speed settings for ultimate control. Low Speed Mode reduces speed in forward to help prevent overtightening of small fasteners while maintaining normal speed in reverse. Precision Wrench Mode pauses before impacting in forward to prevent over-tightening and lowers speed in reverse when a fastener is loose. High Speed Mode operates at normal speed in both forward and reverse.
