Features

Black oxide coating enhances wear resistance and provides modest lubricity for metal drilling.

HSS base material delivers reliable performance across steel, cast iron, and aluminum.

Jobber-length design offers increased reach for through-holes and work in confined spaces.

Precision-ground flute geometry supports steady chip evacuation and reduces heat buildup during cutting.

General-purpose drilling for a range of workshop and fabrication tasks.

Use with conventional cutting fluids or light lubrication to extend bit life and improve hole quality.

Suitable for drilling ferrous and non-ferrous metals and certain plastics when using appropriate feeds and speeds.
