Features

Large-diameter drilling capability: 21/32″ hole in metal and non-ferrous materials when used with proper lubrication and feed rates.

Reduced shank design: 3/8″ shank minimizes interference in tight drill setups while preserving the large cutting diameter.

Durable HSS construction: suited for standard metal drilling tasks with predictable wear resistance.

DWDRSD series reliability: emphasizes consistent hole accuracy and steady cutting performance in typical workshop environments.

Practical use cases: brackets, plates, and fabrication tasks requiring a single large-diameter hole in steel, aluminum, brass, and similar metals.

Operational guidance: apply appropriate lubrication and maintain moderate feeds to manage mechanical stress from larger holes.

Tips for use: secure the workpiece, use a pilot hole if needed, and monitor chip evacuation to prevent binding.
