Bosch 3 Piece Blue Granite Masonry Drill Bit Set

The Bosch 3 Piece Blue Granite Masonry Drill Bit Set is a professional-grade CYL-5 drill bit set designed for drilling fixing holes in concrete, natural stone, and artificial stone. Supplied in three commonly used diameters — 5mm, 6mm, and 8mm — it is well suited to general masonry work on site or in domestic settings.

Bosch's in-house carbide blend combined with diamond-ground cutting edges gives each bit exceptional wear resistance, making these suitable for demanding, repetitive drilling tasks. The 2-flute vario design features a short, variable incline that reduces flute friction and improves dust removal, helping to extend bit life and maintain drilling efficiency.

The Bosch Power Grip Shank System delivers 100% power transfer from machine to bit, eliminating power loss and reducing wear on both the bit and the drill. The cylindrical shank is compatible with three-jaw drill chucks, making these bits suitable for use with all corded or cordless impact drills. Each bit carries the PGM Masonry Drill Bit Association Board quality mark, confirming compliance with tight tolerances for accurately sized holes and a firm hold on fixings.
