Metal Drill Bit Set - 8% Cobalt, 135 degree
25 Piece: 1mm to 13mm
Cobalt HSS Metal Drill Bits are fully ground bits constructed of M42 High Speed Steel for the maximum combination of strength, heat & wear resistance and bit life at higher cutting temperatures and are the preferred drill for harder materials especially stainless steel. 8% cobalt HSS provides 5x 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' or 'self centering' tip.
