High accuracy & Best quality
Gun drills - Deep hole drilling
The characteristic of the single flute gundrilling process is that coolant is fed through the coolant hole in the tool and exits along with the chips in the v-shaped groove (flute) on the drill tube from the drilled hole. the coolant also provides lubrication to the drill periphery.
Gun drills are used for deep hole drilling—a depth-to-diameter ratio of 10~150 : 1. Gun barrels are the obvious example; hence the name.
Tool parts
Gundrill system needs a chip box and some steady rests for supporting gundrills. We need some parts to link the machine with gundrills.

- Steady rest bush
To use gundrills at a deep hole drilling machine, we need guide bush, front rubber bush and steady rest bush for supporting the gundrills. Vastuna also supply the bushes and tool parts.
Guide bush
The material is tool steel. It is very precise with gundrills. It’s holding the gundrills when the gundrill getting into the workpiece.
Front rubber bush & Steady rest bush
Front rubber bush – The material is rubber. It’s for stopping the chips at the end of chip box and sealing.
Steady rest bush – The material is rubber. It’s for supporting the gundrills at steady rests. The special material can reduce the gundrills vibrations when drilling.
Guide bush adaptors
We also need drill driver adaptors to link the gundrills with machine spindle.
