Features

Reduced-shank design (21/32″) lets this drill bit work in machines with smaller chuck capacities while maintaining a 1/2″ cutting diameter.

3-flat shank provides positive drive and minimizes slippage in drill chucks for consistent performance.

High-Speed Steel construction offers improved heat resistance for metalworking and fabrication tasks compared to standard carbon steel bits.

D/A3F Series is built for reliable, everyday drilling in workshop environments.

Versatile use cases include drilling through metals such as steel and aluminum in handheld drills, drill presses, and CNC machines that support 1/2″ diameter bits with this shank geometry.
