Irwin Granite Masonry Drill Bit

The Irwin Granite Masonry Drill Bit measuring 14.0mm diameter x 160mm length represents heavy-duty drilling capability for the largest fixing applications. This substantial diameter is used for major structural fixings, large bracket systems, heavy-duty anchor installations, and the most robust mounting work in granite, concrete and natural stone where ultimate strength and holding power are essential. Featuring an extra hard, thicker carbide tip, this 14mm bit can drill up to 40% more holes than conventional masonry drill bits, delivering outstanding durability even under the most demanding professional conditions. The innovative rounded cutting edges provide 50% more accurately sized holes per bit, ensuring large fixings seat correctly and maintain their load-bearing integrity throughout their service life. At 160mm overall length, this drill bit combines substantial diameter with extended reach, making it the professional's choice for major structural work, heavy-duty installations, and applications where maximum fixing strength in very hard materials is non-negotiable.
