Irwin Granite Masonry Drill Bit

The Irwin Granite Masonry Drill Bit at 6.5mm diameter x 105mm length offers a specialist size for specific fixing applications. This intermediate diameter is particularly useful for certain proprietary fixing systems and situations where the gap between 6mm and 7mm sizes makes a critical difference to fixing performance in granite, concrete and natural stone. The extra hard, thicker carbide tip on this 6.5mm bit enables drilling of up to 40% more holes than conventional masonry drill bits, delivering outstanding longevity and value. The rounded cutting edges produce 50% more accurately sized holes per bit, which is especially important with this less common diameter where precision hole sizing ensures optimal fitting compatibility. With a 105mm overall length, this drill bit provides ample drilling depth for standard and slightly deeper applications, making it a valuable specialist addition to professional toolkits where precise diameter requirements must be met.
