Irwin HSS TCT Drill Bit – 10502651

This 6mm Irwin HSS TCT drill bit is a workshop essential for drilling hardened materials at a commonly required diameter. The 6mm size is extensively used across mechanical engineering, maintenance, and fabrication work for creating bolt holes, clearance holes, and mounting points in tough 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 moment drilling begins, whilst reducing the drilling pressure required for smoother, more controlled operation. The Chrome Vanadium Steel body, hardened to 56 Rockwell C, ensures the drill bit maintains its integrity even under the demanding conditions of drilling hard materials. This 6mm bit is engineered for use with stationary drilling machines and performs optimally when operated with a 3-6% coolant emulsion. Following Irwin's coolant recommendation significantly extends tool life and maintains consistent cutting performance throughout the drill bit's service life.
