851/1 BTH bits, PH 2 x 25 mm

High quality bits for Phillips screws 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. Extra-hard design, ¼” hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
