Bosch SDS-plus-7 Drill Bit 25mm x 400mm x 450mm 2608586726 Bosch SDS-plus-7 drill bits provide accurate holes, even through rebar, whilst still being particularly durable. This Bosch SDS hammer drill bit has a solid tungsten carbide head with four-cutter geometry making it extremely robust. The main cutter is supported by the secondary cutters during drilling - this causes the concrete to be broken down into smaller particles, making it virtually impossible for the bit to get jammed in concrete with rebar. The result is a fast but smooth drilling action.
