Bosch Expert 7x - drill bit set

Bosch Expert 7x - Drill bit set - for concrete, reinforced concrete, granite, hardened concrete, gneiss - 7 pieces - 5 mm, 6 mm, 8 mm, 10 mm, 12 mm - SDS-plus - length: 115 mm, 165 mm

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 doesn't jam and presents no weakness on impact.
