IRWIN HSS TCT Tip Drill Bit 10.5mm (125mm OL, 90mm WL)
Precision IRWIN 10.5mm TCT drill bit for hardened steel, cast iron & alloys. 125mm length, tungsten carbide tip.
The IRWIN HSS TCT Tip Drill Bit delivers precision performance for drilling hardened materials using stationary machines. Its tungsten carbide tip (TCT) ensures durability when working with hardened steel, cast iron, bronze alloys, and manganese alloyed steel. The C2 carbide tip can drill materials up to 50 Rockwell C hardness, while the four-facetted grind design reduces drilling pressure and improves centring accuracy. The drill body is made from chrome vanadium steel, hardened to 56 Rockwell C for long-lasting strength.
