Irwin 10502666 7.5mm HSS TCT Tip Drill Bits

General description This high-quality IRWIN® HSS TCT tip drill bit is designed for precision drilling in hardened materials. It is suitable for use with stationary machines and is ideal for drilling through steel, cast iron, bronze alloys, and manganese steel. The drill bit features a durable chrome vanadium steel body, hardened to 56 Rockwell C, and a four-faceted ground tip that allows for low drilling pressure and accurate centering. The C2 carbide tip is capable of drilling materials with a hardness of up to 50 Rockwell C. Technical specifications Diameter: 7.5mm Total length: 109mm Working length: 69mm Body material: Chrome Vanadium Steel, hardened to 56 Rockwell C Tip material: C2 Carbide Maximum hardness of material: 50 Rockwell C Usage For optimal performance and extended lifespan, it is recommended to use a coolant during drilling. A 3-6% emulsion is suggested to help prolong the life of the drill bit.

The Irwin Metric TCT (Tungsten Carbide Tipped) Drill Bits offer precision drilling with stationary machines in hardened steel cast iron bronze alloys and manganese alloyed steel. The C2 Carbide Tip will drill hardened material up to a hardness of 50 Rockwell C and is four facetted ground for low drilling pressure and perfect centring. The body of the drill bit is made from Chrome Vanadium Steel hardened to 56 Rockwell C. A coolant should always be used when drilling with TCT twist drill bits. Irwin suggest the use of a 3- 6% emulsion. The coolant will extend the lifetime of the drill bit.Irwin HSS TCT tip drill bit.
