Cobalt Twist Drills

M35 Cobalt Twist Drills — Australian Stock

Stop fighting with standard HSS drills on tough materials. These M35 Cobalt Twist Drills are built for the jobs that chew through ordinary bits — stainless steel, hardened alloys, cast iron, and heat-resistant metals. With 5% cobalt alloyed into the high-speed steel, they run cooler, stay sharper longer, and hold their edge where standard drills give up.

Priced per drill. Available in 29 sizes from 1mm to 13.5mm — in stock in Australia and ready to ship.
