Features

Extended 12″ reach enables deep-hole drilling in hard-to-access joints typical of aircraft assemblies.

Cobalt alloy offers enhanced heat resistance and longer life when drilling tough metals.

Extension design provides stable cutting in confined workspaces, reducing the need to reposition.

Long-form geometry helps maintain hole quality over extended drilling sessions in metal.

Specifically suited for maintenance and fabrication tasks in aerospace and metalworking environments requiring deep-hole access.
