General description The Irwin HSS TCT (Tungsten Carbide Tipped) drill bit is designed for precision drilling in hardened steel, cast iron, bronze alloys, and manganese alloyed steel using stationary machines. The C2 Carbide Tip allows for drilling in materials with a hardness of up to 50 Rockwell C, featuring a four-faceted ground design that ensures low drilling pressure and perfect centering. The drill bit's body is constructed from Chrome Vanadium Steel, hardened to 56 Rockwell C, providing durability and strength. Technical specifications Diameter: 5.5mm Total length: 93mm Working length: 57mm Body material: Chrome Vanadium Steel Hardness of body: 56 Rockwell C Tip material: C2 Carbide Maximum hardness for drilling: 50 Rockwell C Usage When using the Irwin HSS TCT tip drill bit, it is essential to apply a coolant to extend the drill bit's lifespan. Irwin recommends using a 3-6% emulsion as a coolant during drilling operations. Other information
