IRWIN HSS TCT Tip Drill Bit 11mm x 142mm
Professional-grade IRWIN HSS TCT tip drill bit (11mm) for hardened steel, cast iron & alloys. High durability with carbide tip.
The IRWIN HSS TCT Tip Drill Bit delivers precision drilling performance in various hardened materials, making it an essential tool for professional applications. Featuring a tungsten carbide tip (TCT), this drill bit is specifically designed for stationary machines and excels when working with hardened steel, cast iron, bronze alloys, and manganese alloyed steel.
The C2 carbide tip ensures durability, capable of drilling materials up to 50 Rockwell C hardness. Its four-facetted ground design reduces drilling pressure while maintaining perfect centring for clean and efficient holes. The drill bit body is constructed from chrome vanadium steel, hardened to 56 Rockwell C, providing strength and longevity even under demanding conditions.
To maximise the lifespan of the drill bit, Irwin recommends using a 3-6% emulsion coolant during operation. This helps prevent overheating and wear, ensuring consistent performance over time.
