Specs

Diameter: 17/32″ (0.53125″)

Shank: 3/8″ reduced shank

Material: Cobalt (high-speed steel cobalt alloy)

Quantity: 1 piece

Brand/Model: D/ACO

Features

Cobalt alloy provides enhanced heat resistance and wear life for drilling hard metals

Reduced 3/8″ shank enables mounting in drills and holders that accept 3/8″ bits

Precision 17/32″ cutting diameter suited for mid-range metal hole drilling tasks

Designed for repeated use in metalworking applications such as fabrication, maintenance, and light production

Ideal for drilling hard metals (e.g., stainless steel and alloy steels) when used with proper feed rates and lubrication

Practical tips: use proper cutting fluid or oil when drilling stainless and alloy steels; maintain steady feed to manage heat; use peck drilling to clear chips

Performance note: cobalt HSS offers longer life and higher heat tolerance than standard HSS under elevated speeds

Use cases: fabrication shop tasks, maintenance routines, and light production holes in metal
