Wera 066104, 867/1 BDC Torx® Bits, TX 20 x 25 mm

Bits for recessed TORX® 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. Come with a 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-D 6.3.
