Designed to withstand high torque, reducing instances of failure. Optimised torsion zone maximises bit life and turning force. Specifically designed to withstand the high forces of today's impact drivers, significantly reducing instances of failure when fixing large screws in place. Features an optimised torsion zone, maximising bit life and turning force when used in extreme applications, as the contoured area of the bit tip flexes with the torque of the impact driver. Reduced breakage and wear in hard and soft joint applications. DeWalt FlexTorq Impact Rated Torsion Bit T10 (5 Pack) in Black. Impact Torsion screwdriver bits.
