The Bosch Impact Tough™ Driver Bit features an Xtended Torsion Zone and has been upgraded to deliver 10X life over a Bosch standard bit. This impact-rated bit absorbs torque peaks to reduce stress on the fastener. The tip of the bit is precision designed and machined for a better-integrated fit and reduced cam out. The bit is made of forged steel to extend bit life and reduce cam out, and it has been enhanced to handle a new generation of higher torque impact drivers. It features laser-etched markings that are easy to read and won’t rub off with repeated use.
