Irwin Granite Masonry Drill Bit

The Irwin Granite Masonry Drill Bit at 8.0mm diameter x 120mm length is designed for substantial fixing and installation work. This popular larger diameter is extensively used for heavy-duty rawlplugs, major bracket installations, batten fixing, and robust mounting applications in granite, concrete and natural stone where maximum fixing strength is essential.

Engineered with an extra hard, thicker carbide tip, this 8mm bit delivers up to 40% more holes than conventional masonry drill bits, providing exceptional cost-effectiveness for professional users. The rounded cutting edges ensure 50% more accurately sized holes per bit, which becomes increasingly important at this diameter where hole accuracy directly impacts fixing performance and load-bearing capacity.

The 120mm overall length provides excellent drilling depth for a wide range of applications, from standard wall construction through to deeper installations, whilst maintaining good control throughout the drilling operation.
