IRWIN HSS Tungsten Carbide Tip Drill Bit 7.0mm
IRWIN HSS TCT Tip Drill Bit (7.0mm) for precision drilling in hardened steel, cast iron & alloys. Chrome Vanadium Steel body for durability.
The IRWIN Metric TCT (Tungsten Carbide Tipped) Drill Bits are precision-engineered for use with stationary machines, offering exceptional performance when drilling hardened steel, cast iron, bronze alloys, and manganese alloyed steel. Featuring a C2 Carbide Tip, these bits are designed to drill materials with a hardness of up to 50 Rockwell C. The four-faceted ground tip ensures low drilling pressure and perfect centring for accurate results.
The drill bit body is crafted from Chrome Vanadium Steel, hardened to 56 Rockwell C, providing durability and resistance to wear. To maximise the lifespan of the TCT twist drill bits, Irwin recommends using a coolant—specifically a 3-6% emulsion—during drilling operations.
