Irwin Granite Masonry Drill Bit

The Irwin Granite Masonry Drill Bit at 10.0mm diameter x 140mm length is designed for heavy-duty professional applications. This substantial diameter is commonly used for large rawlplugs, major structural fixings, heavy bracket installations, and robust mounting work in granite, concrete and natural stone where maximum load-bearing capacity is required.

Engineered with an extra hard, thicker carbide tip, this 10mm bit delivers up to 40% more holes than conventional masonry drill bits, providing outstanding durability for demanding trade use. The innovative rounded cutting edges ensure 50% more accurately sized holes per bit, which is crucial at this diameter where precise hole sizing directly affects the integrity and strength of structural fixings.
