Irwin IRW10501911 Granite Drill Bit 10.0 x 140mm

IRWIN Granite drill bit designed for impact and percussion drilling in very hard materials such as granite, concrete, and natural stone. It features a durable carbide tip that enables drilling up to 40% more holes than standard masonry bits and rounded cutting edges for increased durability and cleaner, more precisely sized holes. The bit has a straight cylindrical shank and an overall length of 140 mm with a 90 mm working length, and a diameter of 10.0 mm. Compatible with standard hammer drills and masonry-impact drills. Use by inserting into the drill chuck and engaging the impact or hammer function for best results in hard materials. The design includes a self-centring head and an extra short drill head for easier control, offering higher wear resistance.
