Bosch® Impact Toughtm 40-piece Drill/drive Custom Case System Set In Blue, Size: 40 Piece

The Bosch 40-Piece Impact Tough Drill/Drive Custom Case Set is compatible with Impact Tough driver bits and drill bits, delivering the best case for the best bits. These bits are impact rated and have been designed to handle the additional torque of today's impact drivers. With the Xtended Torsion Zone, the driver bits have been upgraded to deliver 10x the life span over standard impact bits. The Xtended Torsion Zone absorbs torque peaks to reduce stress at the bit tips. The black oxide drill bits provide longer life than standard drill bits, thanks to their tip design and black oxide coating. The durable, well-designed case provides tilt-in/tilt-out convenience for easy access to the bits. Since it's customizable, it helps increase user productivity by reducing time searching for the right bit.
