Irwin Granite Drill Bit 8.0mm x 200mm

The Irwin Granite drill bit range have been designed for for impact / percussion drilling in very hard materials such as granite, concrete and natural stone.

They can drill 40% more holes than conventional masonry drill bits due to an extra hard, thicker and more robust carbide tip. The rounded cutting edges means higher durability resulting in 50% more accurately sized holes per drill bit.
