Irwin Granite Masonry Drill Bit

The Irwin Granite Masonry Drill Bit in 3.0mm diameter x 70mm length is the perfect choice for precision drilling in smaller diameter applications. This compact size is ideal for fixing lighter brackets, smaller rawlplugs, and delicate mounting work in granite, concrete and natural stone where accuracy is paramount. The extra hard, thicker carbide tip on this 3mm bit enables you to drill up to 40% more holes than conventional masonry drill bits, whilst the rounded cutting edges deliver 50% more accurately sized holes per bit. This means cleaner, more precise holes every time, essential when working with smaller fixings where tolerance is critical. At 70mm overall length, this drill bit offers excellent control and manoeuvrability in tight spaces whilst providing sufficient depth for most standard fixing applications. The robust construction ensures reliable performance even in the hardest masonry materials.
