Designed to withstand the high forces of today's impact drivers, significantly reducing the 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. Extreme FlexTorq screwdriver bits are designed to withstand the high forces of todays impact drivers. This significantly reduces the instances of failure when fixing large screws in place. Heat treated to resist breakage and wear. Shock resistant tool steel for maximum durability. Hardened core for extra strength and reduced breakage. Specifications: Bit Type: Torx, Hex Bit Size: T30, Length: 57mm, Product Range: DeWalt - Extended FlexTorq Bits. Impact Torsion screwdriver bits specifically designed to withstand high torque operation in impact drivers. Eliminates rounded screw heads and wobbles with less than 4° movement.
