Features

Product identification: This 1-piece cobalt drill bit (35/64 in diameter) with a 1/2 in reduced shank (D/ACO).

High-heat resistance: Cobalt alloy maintains hardness under elevated temperatures, extending bit life when drilling hard metals such as stainless steel and alloy steels.

Reduced shank design: 1/2″ reduced shank provides secure engagement in standard tooling setups, helping minimize runout and stabilize hole location.

Precision-ground edges: Sharp, evenly ground cutting surfaces reduce wandering and deliver cleaner hole finishes in tough materials.

Uncoated cobalt chemistry: Hardness is preserved at high temperatures, enabling repeated use in demanding fabrication tasks.

Ideal use cases: Metalworking environments like automotive, fabrication, and tooling where larger-diameter holes in hard metals are routine.

Operational tip: For best results, use a steady feed rate and appropriate lubrication when drilling hard metals.
