Maximum Precision - The HSS Twist Drill Bit Ground is for drilling through metal with maximum precision. The bit's exposed 135-degree self-centring split-point tip combines active cutting and perfect more→centring without wandering, delivering maximum precision. The split-point tip also eliminates any need to pre-punch or pilot drill for up to 10 mm. This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges. This bit is designed for drilling holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics.…

The Irwin Granite drill bit range has been designed for impact / percussion drilling in very hard materials such as granite, concrete and natural stone. They can drill 40% more holes than conventional more→masonry drill bits due to an extra hard, thicker and more robust carbide tip. The rounded cutting edges mean higher durability resulting in 50% more accurately sized holes per drill bit.The Irwin IRW10501914 Granite drill bit has the following dimensions:Drillbit diameter: 14.0mmTotal length: 160mmWorking Length: 100mm
