The Bosch Custom Case System works with Driven Bit clips, providing the best case for the best bits. The clips come loaded with bits, which snap in/snap out of the case easily, allowing for easy access to carry only the bits needed. 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 bit’s 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 won’t rub off with repeated use, as well as the distinctive Bosch silver sleeve. The strong magnetic tip helps hold the screws on the bit.
