Sutton Tools Ultrabit Screwdriver Bit is a precision-made, heavy-duty screwdriver bit that has been designed to withstand high torque screwing and so last 12 times longer than standard bits. It features a shock absorber zone with an impact torsion neck and it has also been equipped with reinforced joints for a stronger link avoiding breakages. The Anti-breakage bit has a reinforced screw head ring for longer impact resistance along with a precise fit that avoids slipping and stripping screw heads.
