Irwin 10502636 HSS TCT Tip Drill Bit 4.5mm

The Irwin Metric TCT (Tungsten Carbide Tipped) Drill Bit is designed for precision drilling in stationary machines. It features a C2 carbide tip capable of drilling hardened materials up to 50 Rockwell C, with a four-facetted, diamond-ground tip for low drilling pressure and accurate centering. The body is made from Chrome Vanadium Steel hardened to 56 Rockwell C. The drill bit is suitable for use on hardened steel, cast iron, bronze alloys, and manganese alloyed steel. Key specifications include a diameter of 4.5 mm, a total length of 80 mm, and a working length of 47 mm. For optimal performance and longevity, a coolant is recommended during drilling, with a 3-6% emulsion suggested.

Usage and materials

Designed for precision drilling in stationary drills, it is suitable for hardened steel, cast iron, bronze alloys, and manganese alloyed steel. Ideal for drilling hard and abrasive materials. A coolant should be used when drilling with TCT twist drill bits, with a 3-6% emulsion recommended to extend the lifetime of the drill bit.

Always use a coolant when drilling with TCT twist drill bits, and consider a 3-6% emulsion to extend the lifetime of the drill bit.
