Wera 066646, 871/1 DC TORQ-SET® Mplus Bits, 1/4" x 32 mm

High quality bits for TORQ-SET® screws. The stronger flanks - when compared with the conventional TORQ-SET® profile - result in 70% more breaking torque and thereby enhanced durability whilst at the same time providing a perfect fit in the screw head. The diamond coating of the bit ensures a secure fit in the screw, reduces the contact pressure required and lowers the risk of slipping. ¼" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
