The BOSCH custom case system comes preloaded with impact tough bits, providing the best case for the best bits. The impact tough bit has an extended torsion zone to absorb torque peaks to reduce stress at the bit’s tip, which allows it to handle a new generation of higher torque impact drivers. The tip on this bit is precision designed and machined for a better-integrated fit. The durable, well-designed case provides tilt-in/Tilt-Out convenience for easy access to the bits. This Customizable organization system helps users increase productivity by reducing time searching for the right bit.
