Bosch Blue Granite Masonry Drill Bit

The Bosch Blue Granite CYL-5 Masonry Drill Bit is engineered for extra-long durability when drilling into concrete, natural stone, and artificial stone. A proprietary carbide blend developed in-house by Bosch, combined with diamond-ground cutting edges, delivers exceptional wear resistance across demanding applications.

Friction from drilled material is significantly reduced thanks to a 2-flute vario design with a short, variable incline, promoting efficient dust removal and prolonging bit life. The Bosch Power Grip Shank System ensures 100% power transfer from machine to bit, eliminating power loss and reducing wear over time.

Compatible with cylindrical shank systems on all corded and cordless impact drills, these bits are available in sizes from 5mm to 12mm across a range of working lengths. Each bit carries the PGM Masonry Drill Bit Association Board quality test mark, guaranteeing tight tolerances, accurately drilled holes, and a firm hold on fixings.
