Features

Cobalt alloy construction provides increased heat resistance for drilling hard metals and alloys, improving long-term bit life under high-speed cutting.

31/64″ cutting diameter enables precise hole sizing for metalworking projects requiring tight tolerances.

Reduced 3/8″ shank preserves a larger body diameter for stability and chip clearance during starting and drilling.

Designed for demanding materials such as stainless steel, alloy steels, and other hard metals.

Sharp cutting edges help maintain hole quality and reduce wandering when starting a hole.

Suitable for use with metalworking drills or drill presses capable of handling cobalt HSS bits.
