Fully ground drill 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 bit for harder materials especially stainless steel. M42 HSS designed for an industrial workshop for daily use for drill press work on hardened steel, stainless steel, alloy steel and cast iron - 8% cobalt HSS provides 5x more life than regular TIN coated HSS drill bits. Increased 135 degree point enables a faster drilling rate, lower feed pressure and features a ‘split point’ or ‘self centering’ tip. Available in 1 mm - 13mm dia.
