Bosch Blue Granite Masonry Drill Bit

The Bosch Blue Granite CYL-5 Masonry Drill Bit in 5mm diameter with a 100mm working length is an ideal choice for precision drilling of smaller fixing holes in concrete, natural stone, and artificial stone. This compact size suits lighter fixing tasks where accuracy and clean hole formation are essential.

The in-house developed carbide blend and diamond-ground cutting edges make this bit exceptionally wear-resistant, while the 2-flute vario design with its short, variable incline minimises friction and clears dust efficiently during drilling. The Bosch Power Grip Shank System ensures every watt of power is transferred directly to the cutting edge, reducing wear and maximising productivity.

Compatible with cylindrical shank systems on all corded and cordless impact drills, it fits standard three-jaw drill chucks with ease. PGM certification confirms compliance with tight tolerances for accurately drilled holes and a firm hold on fixings.
