Bosch 7 Piece Blue Granite Masonry Drill Bit Set

The Bosch 7 Piece Blue Granite Masonry Drill Bit Set is a professional-grade masonry drill bit set designed for drilling fixing holes in concrete, natural stone, and artificial stone. Built around Bosch's CYL-5 technology, this set delivers extra-long durability and is suitable for use with all corded or cordless impact drills.

The CYL-5 bits combine a Bosch-developed carbide blend with diamond-ground cutting edges, making them highly wear-resistant in demanding drilling applications. The 2-flute vario design features a short, variable incline that reduces friction along the flute, improving dust removal and minimising wear during use.

The Bosch Power Grip Shank System ensures 100% power transfer from machine to bit, allowing full drilling power to be applied with no energy loss. The cylindrical shank is compatible with three-jaw drill chucks, making this set straightforward to use with standard corded and cordless impact drills.

As independent verification of quality, each bit carries the PGM Masonry Drill Bit Association Board quality test mark, confirming compliance with tight tolerances for accurately drilled holes and a reliable hold on fixings. This set is well suited to contractors, builders, and tradespeople who regularly drill into masonry and require consistent, dependable performance across a range of fixing sizes.
