Impact Tough DDMS40 Drill Bit Set, 40-Piece, HCS, Black Oxide

The Bosch custom case system 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 todays impact drivers. With the Xtended Torsion Zone, the driver bits have been upgraded to deliver 10X life 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 or tilt-out convenience for easy access to the bits. Since its customizable, it helps increase user productivity by reducing time searching for the right bit. This jobsite tough case features a secure case latch and rubber bumpers.
