Bosch Impact Tough™ impact driver bits have been upgraded to deliver 10X life over standard impact bits. With an XTEND torsion zone, precision engineering and heat-treated manufacturing process, these bits deliver tough torque and power for longer – and with less cam out. These Impact Tough™ bits are an impact-rated line of screw driving bits, double-ended bits, nutsetters, sockets and bit holders that have been enhanced to handle a new generation of higher torque impact drivers. These bits also come with high-visibility sleeves for greater user convenience.
