Wera Tools 851/1 BDC Drive Bits

Wera Tools 851/1 BDC drive bits are high-quality insert bits with tiny diamond particles on the bit tip—ensuring a more secure fit of the bit in the screw and reduces the contact pressure required and lowers the risk of slipping. One of the greatest problems with power tool applications is that the conventional bit easily slips out of the head of the screw (cam-out). Particularly when applications involve sensitive materials or high-quality surfaces are involved, bits with a diamond coating ensure that work is done safer, faster, and at a lower cost. These drive bits also come with Torsion zone—where kinetic energy is diverted from peak loads—and softer BiTorsion zone prevents the bit tip from twisting under peak loads, which greatly helps extend the 851/1 BDC drive bits service life. Highlights and features: * For Phillips screws * Diamond coating for a secure fit in the screw, literally bites into the screwhead to prevent cam-out * BiTorsion zone absorb peak loads * Considerable reduction in the risk of breakage, significant increase in service life * 1/4 in. hexagon drive (Wera connecting Series 1) suitable for holders as per DIN ISO 1173-D 6.3 * Wera's Take It Easy Tool Finder System: color coding accordingly to profile and sizes Show Less
