IRWIN HSS TCT Tip Drill Bit, 3.5mm, 70mm
High-performance IRWIN TCT drill bit (3.5mm) for hardened steel, cast iron, and alloys. 70mm length with carbide tip.
The IRWIN HSS TCT Tip Drill Bit is a precision tool designed for stationary machines, offering exceptional performance in drilling hardened steel, cast iron, bronze alloys, and manganese alloyed steel. The tungsten carbide tipped (TCT) construction ensures durability and accuracy, making it ideal for tough materials. The C2 carbide tip can effectively drill materials with a hardness of up to 50 Rockwell C, while the four-faceted ground design reduces drilling pressure and enhances centring precision.
The body of the drill bit is crafted from chrome vanadium steel, hardened to 56 Rockwell C for added strength and longevity. Using a coolant (3-6% emulsion) is recommended to maximise the bit’s lifespan and improve cutting performance.
