This 5mm Irwin HSS TCT drill bit is one of the most commonly used sizes in engineering and fabrication work involving hardened materials. The 5mm diameter is ideal for a wide range of fastener holes, mounting applications, and general drilling tasks in demanding materials. Equipped with a C2 tungsten carbide tip, this drill bit excels when working with hardened steel, cast iron, bronze alloys, and manganese alloyed steel up to 50 Rockwell C hardness. The four-facetted ground tip provides two essential benefits: it ensures perfect centring for accurate hole placement, and it reduces the drilling pressure required, making the operation smoother and more controlled. The Chrome Vanadium Steel body, hardened to 56 Rockwell C, offers the durability and strength needed for professional applicatio...
