Super Long HSS Drill Bit - 480mm Length

TUSK Cobalt HSS Metal Drill Bits are fully ground drill bits constructed of M35 High Speed Steel for the best combination of strength, heat resistance, wear resistance and bit life at higher cutting temperatures and are the preferred drill for harder materials especially stainless steel.

5% cobalt HSS provides 3x more life than regular TIN coated HSS drills. Increased 135 degree point enables a faster drilling rate, lower feed pressure and features a 'split point' and 'self centering' tip.
