Wera Phillips Screwdriver Bit, PH2 Tip

Wera BDC BiTorsion® bits, diamond-coated

Wera BiTorsion bits have special heat treated torsion zone that has a lower hardness than the shaft tip. The peak loads are cushioned preventing premature breakage and distinctly extend the service life.
Wera BiTorsion bits are recognisable through the letter B (for example, 851/1 BDC), their gold colour and green band.
