059540 Wera screwdriver Bit Bth Ex-Hard Ph1X50

BiTorsion screwdriver bit works to absorb damaging peak loads and provides a considerable increase in tool life. Specially designed for fastening into wood. Under these conditions, a constant increase in torque is developed, which places an immense strain on the bit. The extra hardness, combined with the softer torque zone, provides improved wear and resistance.
