TUSK HSS METAL DRILL BITS are constructed of M2 High Speed Steel for the best combination of strength, heat resistance and wear resistance. Great general purpose drill bits to suit a builder, electrician, plumber or DIV handyman to deal with timber, aluminium or steel.
 
Fully ground HSS drill bits feature a Titanium Nitride (liN) gold coating for longer life with an increased 135 degree point enabling a faster drilling rate, lower feed pressure and features a 'split point' or 'self centering' tip.
