IRWIN HSS TCT Tip Drill Bit, 8.0mm, Tungsten Carbide, 177mm

The IRWIN HSS TCT Tip Drill Bit is designed for precision drilling in hardened materials such as steel, cast iron, bronze alloys, and manganese alloyed steel. Featuring a Tungsten Carbide Tipped (TCT) design, it offers superior durability and performance, capable of drilling materials with a hardness of up to 50 Rockwell C.

The four-facetted ground C2 Carbide Tip ensures low drilling pressure and perfect centring, resulting in cleaner, more accurate holes. The drill bit body is crafted from Chrome Vanadium Steel, hardened to 56 Rockwell C for added strength and longevity.

Usage Tips

For optimal performance and extended tool life, always use a 3-6% coolant emulsion when drilling with this bit. This helps to reduce heat buildup and prolongs the bit's cutting efficiency.
