Irwin Granite Masonry Drill Bit

The Irwin Granite Masonry Drill Bit measuring 6.0mm diameter x 160mm length is specifically designed for deeper drilling applications where extended reach is essential. This longer variant is ideal for drilling through thick walls, deep fixing installations, and situations where you need to penetrate substantial masonry depths in granite, concrete and natural stone. Engineered with an extra hard, thicker carbide tip, this 6mm extended-length bit can drill up to 40% more holes than conventional masonry drill bits, maintaining its performance even during demanding deep-drilling operations. The rounded cutting edges provide 50% more accurately sized holes per bit, ensuring precision is maintained throughout the entire drilling depth. At 160mm overall length, this drill bit offers significantly extended reach compared to standard lengths, making it invaluable for through-wall drilling, deep cavity work, and installations requiring greater penetration depth whilst still maintaining the control needed for accurate hole placement.
