Manufactured from high-grade tool steel tempered with a custom heat treatment, impact-rated bits are designed to reduce breakage and extend bit life up to 5x longer than standard bits used in high torque metal-to-metal applications such as steel decking, hat channel, wall panel construction, resilient channel, metal truss assembly, window framing and aluminum extrusions. The bit narrows just above the hex shank to absorb excess torque and impact energy that would otherwise transfer to the tip causing it to fracture. A variety of bits including #2 Phillips, #2 square, and Rex Drive in sizes ranging from 7¾  to 9 inches long are offered for the full range of DuraSpin tools.
