Irwin Granite Drill Bit 10501905 7.0 x 110mm

The Irwin Granite drill bit range is designed for impact and percussion drilling in very hard materials such as granite, concrete, and natural stone. These bits feature an extra hard, thicker carbide tip to enable drilling more holes than conventional masonry bits, and rounded cutting edges that improve durability and hole accuracy. The drill bits are 7.0 mm in diameter with an overall length of 110 mm and a working length of 65 mm, and are compatible with standard drill chucks that accommodate 7 mm bits. They are intended for use with tools configured for masonry drilling, and guidance emphasizes steady pressure during drilling and cooling with water to maintain performance over extended use.
