Built from premium S2 steel, these bits are made to handle high-torque work. The precise-machined tip is intended to seat cleanly to help reduce stripping, while the optimized torsion zone is designed to absorb torque and help cut down on bit breakage. A 1/4″ quick-release shank makes them easy to use with compatible drivers and holders.
