Wera Diamond Bits
- Premium Wera driver bits
- Diamond coated for slip-free driving
- BiTorsion zone for long life
- 25mm long
Wera diamond coated bits bite into the screw head to dramatically reduce cam-out and the pressure required to drive the screw. The hardness of the shaft is reduced by about 20% in the BiTorsion zone to absorb peak loads that occur during screwdriving and prevent premature wear, breakage and screw damage.
