About this product
This 3.0mm Irwin HSS TCT drill bit is designed for precision drilling with stationary machines in hardened materials, including hardened steel, cast iron, bronze alloys and manganese alloyed steel up to 50 Rockwell C hardness. The C2 tungsten carbide tip is four-facetted ground, giving perfect centring from first contact and reducing the drilling pressure needed on harder materials. The body is made from Chrome Vanadium Steel, hardened to 56 Rockwell C for durability and wear resistance. Irwin recommends using a 3-6% coolant emulsion during drilling to maintain cutting efficiency and extend the bit's life. Overall length is 61mm, with a working length of 33mm. Supplied as a single drill bit.
