The Bosch Custom Case System is compatible with Driven Bits, delivering the best case for the best bits. The Bosch Driven range of screwdriving bits delivers 50X life over the Bosch standard bit. The Driven bit has a torsion design built to last, with a new tapered design that absorbs torque peaks to reduce stress at the bits tip. This allows it to handle a new generation of higher torque impact drivers. The tip on this bit is precision designed and CNC milled for a better-integrated fit. The bit features clear head-type markings (or laser markings) that are easy to read and wont rub off with repeated use, as well as the distinctive Bosch silver sleeve. The bit tips provide a magnetized force to hold the screws on the bit.
