TUSK HSS Metal Drill Bits are constructed of M2 High Speed Steel for the best combination of strength, heat resistance and wear resistance. Fully ground HSS drill buts with Titanium Nitride (TiN) coating for longer life with an increased 135 degree point enabling a faster drilling rate and lower feed pressure. Suitable for alloyed and non-alloyed steel, soft stainless steel, soft cast iron, aluminium, copper, brass, bronze and hard plastics and feature a 'split point' or 'self centring' tip.
