Gundrill 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.
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.
The material is tool steel. It is very precise with gundrills. It’s holding the gundrills when the gundrills 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.
We also need drill driver adaptors to link the gundrills with machine spindle.
