The Bosch Custom Case System works with Impact Tough Bit clips, providing the best case for the best bits. Impact Tough Insert Bits have been upgraded to deliver 10X life over standard impact bits. They have an Xtended Torsion Zone to absorb torque peaks to reduce stress at the bit tips, which is important for today's high-torque impact drivers. The clips come loaded with eight bits, which snap in/snap out of the case easily, allowing for easy access to carry only the bits needed. The clips provide easy removal of bits with tilt-in/tilt-out convenience. This customizable organization system features a durable, well-designed case to help users increase productivity by reducing time searching for the right bit.
