This 8mm Irwin HSS TCT drill bit is a popular size for industrial drilling applications in hardened materials. The 8mm diameter is extensively used across engineering, fabrication, and maintenance work for creating substantial fastener holes, mounting points, and structural connections in demanding materials. Featuring a C2 tungsten carbide tip, this drill bit is designed to penetrate hardened steel, cast iron, bronze alloys, and manganese alloyed steel up to 50 Rockwell C hardness. The four-facetted ground tip delivers precise centring from the start of drilling, whilst reducing the drilling pressure required for more controlled operation. This is particularly important at 8mm diameter where maintaining accuracy under higher forces is essential. The Chrome Vanadium Steel body, hardened to...
