Features

Cobalt (M35) HSS construction for improved wear resistance and heat tolerance when drilling through hard metals such as stainless and alloy steels.

Large diameter of 1-3/16″ enables substantial through-holes, reducing the number of passes in metal parts.

1/2″ reduced shank design (shank size) for a compact, rigid connection within suitable tooling setups.

Durable design supports production runs in metal fabrication, repair, and equipment maintenance scenarios.

Best results when paired with appropriate cutting fluid or coolant to manage heat and chip evacuation.

Suitable for drilling through stainless steel and hard alloys where conventional HSS bits wear quickly.
