DeWalt FlexTorq screwdriver bits are designed to withstand the high forces of today's impact drivers, significantly reducing instances of failure when fixing large screws. The optimised torsion zone maximizes bit life and turning force in extreme applications. The contoured area of the bit tip flexes with the torque of the impact driver, transferring maximum torque through the screw and maximizing life while reducing breakage and wear in hard and soft joint applications. This pack contains 5 x PZ1 x 50mm bits.
