IRWIN HSS TCT Tip Drill Bit 5.5mm (93mm Length)
Precision IRWIN TCT drill bit (5.5mm) for hardened steel, cast iron & alloys. Chrome Vanadium Steel body for durability.
The IRWIN HSS TCT Tip Drill Bit is designed for precision drilling in hardened materials, making it an essential tool for professional and industrial applications. Featuring a Tungsten Carbide Tipped (TCT) design, this drill bit excels in drilling hardened steel, cast iron, bronze alloys, and manganese alloyed steel, with a capability to penetrate materials up to 50 Rockwell C hardness.
The four-facetted ground C2 Carbide Tip ensures low drilling pressure and perfect centring, enhancing accuracy and efficiency. The drill bit's body is constructed from Chrome Vanadium Steel, hardened to 56 Rockwell C, ensuring durability and extended tool life.
For optimal performance, it is recommended to use a 3-6% emulsion coolant when drilling with this TCT twist drill bit. This practice significantly prolongs the drill bit's lifespan and maintains its cutting efficiency.
