The Irwin Granite Masonry Drill Bit measuring 8.0mm diameter x 200mm length combines substantial diameter with extended reach for demanding deep-drilling applications. This long variant is specifically designed for drilling through thick walls, deep cavity installations, and through-wall applications in granite, concrete and natural stone where both diameter and depth are critical. Featuring an extra hard, thicker carbide tip, this 8mm extended-length bit can drill up to 40% more holes than conventional masonry drill bits, maintaining exceptional performance even during prolonged deep-drilling operations. The rounded cutting edges provide 50% more accurately sized holes per bit, ensuring precision is maintained throughout the entire 200mm drilling depth. This drill bit is invaluable for professional applications including through-wall services, deep batten fixing, and substantial installations in thick masonry construction where standard-length bits simply cannot reach, making it an essential tool for serious trade work.
