Irwin Granite Masonry Drill Bit

The Irwin Granite Masonry Drill Bit at 6.0mm diameter x 100mm length is a highly versatile size suitable for heavier-duty fixing applications. This diameter is commonly used for larger rawlplugs, substantial bracket installations, and medium-weight mounting work in granite, concrete and natural stone where stronger fixings are required. Featuring an extra hard, thicker carbide tip, this 6mm bit delivers up to 40% more holes than conventional masonry drill bits, providing exceptional durability and cost-effectiveness. The rounded cutting edges ensure 50% more accurately sized holes per bit, which is particularly important at this diameter where precise hole sizing directly affects the holding power of fixings. The 100mm overall length provides excellent drilling depth capability for standard wall construction whilst maintaining good control and stability, making this an essential bit size for professional tradespeople and serious DIY enthusiasts alike.
