Tackle heavy-duty fastening tasks with confidence using the Dewalt DT7391T-QZ impact torsion screwdriver bits. The built-in flexible torsion zone absorbs intense torque peaks from your impact driver, significantly reducing the risk of bit breakage. Thanks to the CNC-machined PZ2 tip, each bit delivers a snug fit into screw heads to prevent cam-out and stripped fixings. Heat-treated hardened steel construction ensures outstanding wear resistance during repetitive driving into timber and tough materials. Featuring a 50 mm length and a standard 1/4" hex shank, these bits provide extended reach without requiring an extra bit holder. This handy pack includes 5 bits to keep your projects running smoothly.
