Features

Cobalt composition provides improved red hardness and wear resistance, extending edge life when drilling tougher metals.

Jobber-length design offers extended reach for deeper, through-hole drilling and accessing recessed areas.

Durable edge life supports longer intervals between re-sharpening under demanding metalworking tasks.

Specifically suited for harder metals where standard high-speed steel bits dull quickly, enabling more productive work cycles.

Packaging includes a 12-piece set, ideal for shop drawers, job sites, and fabrication workflows needing consistent supply of cobalt bits.

Includes 12 cobalt jobber-length drill bits in 9/32″ diameter (D/ACO Series).

Cobalt-based finish emphasizes heat resistance for repeated drilling in hard metals.

Designed for metalworking applications requiring reliable performance in challenging materials.
