Wera 851/4 BDC BiTorsion Diamond Phillips Screwdriver Bits

BiTorsion bits for Phillips screws with tiny diamond particles on the bit tip. This ensures a secure fit of the bit in the screw, reduces the contact pressure required and lowers the risk of slipping. Comes with Torsion zone – where kinetic energy is diverted from peak loads – and softer BiTorsion zone to prevent the bit tip from twisting under peak loads. This greatly extends the product service life; ¼” hexagon, suitable for holders as per DIN ISO 1173-F 6.3. Features and Benefits:
: For Phillips screws
: BiTorsion zone to absorb peak loads
: Considerable reduction in the risk of breakage, significant increase in service life
: Diamond coating for a secure fit in the screw, literally bites into the screwhead to prevent cam-out
: 1/4″ hexagon drive (Wera connecting series 4) Contents: 851/4 BDC bits, PH 1 x 50 mm
