Features

Extended reach of 6″ enables drilling in deep cavities and tight spaces typical in aerospace maintenance and fabrication.

Cobalt alloy construction provides enhanced heat resistance and wear life when drilling through hard metals such as stainless steel and alloy steels.

Precision No. 37 diameter supports consistent hole size for critical-fit assemblies.

Single bit designed for metalworking tasks requiring durable, long-life performance in demanding environments.

Best paired with appropriate speed/feeds for cobalt bits to maximize life and performance.

Use cases include deep-pocket drilling in engine bays, fuselage components, and fabrication work where reach is critical.
