A gundrill tool differs from a conventional twist drill by its unique head geometry.
Gun drill machine.
Gundrilling is a deep hole drilling process that uses a long thin cutting tool to produce holes in metal at high depth to diameter ratios.
It permits high quality deep hole drilling.
Gundrilling uses internal coolant and chips exit through a groove in the tool for a clean and accurate drilling process.
