Bosch Expert 7X 4-Cutter Head 3X Life SDS Plus Masonry Drill Bit 6mm 115mm Pack of 30

Lasts up to 3x longer than a standard drill bit - Drilling through reinforced concrete is a tough job, and it has traditionally taken its toll on drill bits. Regular two-cutter bits get stuck in rebar and they eventually break. The Full Carbide Head on the Expert SDS plus-7X is an advanced 4-cutter design made from a single piece of the toughest metal: It doesnÂ’t jam and presents no weakness on impact. Thanks to Bosch Carbide Technology and the Full Carbide Head, the Expert SDS plus-7X lasts far longer than regular hammer drill bits. It punches through rebar effectively so there is no need to stop, re-target or change bits when you strike steel. For construction professionals drilling concrete and reinforced concrete regularly, for example for fixings and installations, the Bosch Expert SDS plus-7X Hammer Drill Bit offers peerless performance, reliability and longevity. It is THE Expert accessory for SDS plus rotary hammer drills. Fits all SDS plus rotary hammer drills.
