Features

High-hardness cobalt composition provides superior wear resistance and heat tolerance during heavy metal drilling projects.

Reduced 3/8″ shank design preserves the cutting geometry while delivering a defined 37/64″ hole size.

Edge retention stays sharper longer, reducing the need for frequent replacements in tough metalwork tasks.

Material compatibility optimized for drilling hard metals such as stainless steel and alloy steel with predictable wear and performance.

Precision hole size specifically sized for 37/64″ diameter requirements in targeted fabrication and machining tasks.

Operational guidance use with proper lubrication and moderate speeds suited to cobalt bits to maximize life and performance.

Ideal for machinists, metal fabricators, and maintenance technicians working on hard-metal assemblies and components.
