About this product
This 5.5mm Irwin HSS TCT drill bit is designed for precision drilling with stationary machines in hardened steel, cast iron, bronze alloys and manganese alloyed steel. The intermediate 5.5mm size suits applications needing tolerances between standard 5mm and 6mm sizes. The C2 carbide tip drills materials up to 50 Rockwell C hardness and is four-facetted ground, giving low drilling pressure, accurate centring and reduced risk of deflection. The body is made from Chrome Vanadium Steel, hardened to 56 Rockwell C for rigidity and wear resistance. Overall length is 93mm with a working length of 57mm. Irwin recommends using a 3-6% coolant emulsion when drilling, which helps maintain cutting performance and extends the life of the carbide edge. Sold as a pack of 1.
