840/1 BTZ bits, 1,5 x 25 mm

BiTorsion bits for hexagon screws with elastic 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; ¼” hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
