IRWIN HSS TCT Tip Drill Bit - 4.0mm
High-precision IRWIN HSS TCT drill bit (4.0mm) for hardened steel, cast iron & bronze alloys. Long-lasting carbide tip.
The IRWIN HSS TCT Tip Drill Bit is specifically designed for precision drilling in hardened materials. Featuring a Tungsten Carbide Tipped (TCT) design, this drill bit can handle hardened steel, cast iron, bronze alloys, and manganese alloyed steel. Its C2 Carbide Tip is capable of drilling materials up to a hardness of 50 Rockwell C, ensuring durability and long-lasting performance.
The four facetted ground tip promotes low drilling pressure and perfect centring, making it highly efficient for stationary machines. Constructed from Chrome Vanadium Steel, the body of the drill bit is hardened to 56 Rockwell C, enhancing its strength and resistance to wear.
For optimal performance, using a coolant (3-6% emulsion) is recommended. This significantly extends the lifespan of the drill bit and ensures clean and precise drilling. Ideal for industrial and professional applications, this drill bit delivers outstanding results in demanding conditions.
