This 3mm Irwin HSS TCT drill bit is a popular choice for general precision drilling in hardened materials. The 3mm diameter strikes an excellent balance between strength and versatility, making it suitable for a wide range of applications in workshops and manufacturing environments. Designed for use with stationary machines, this drill bit features a C2 tungsten carbide tip that can penetrate hardened steel, cast iron, bronze alloys, and manganese alloyed steel up to 50 Rockwell C hardness. The four-facetted ground tip design ensures perfect centring from the first contact, whilst reducing the drilling pressure required – particularly beneficial when working with harder materials. The Chrome Vanadium Steel body is hardened to 56 Rockwell C, providing excellent durability and resistance t...
