Retrofittable Spray Mist Coolant System

A retrofittable low-cost spray mist coolant system that allows deep hole drilling applications to be carried out on any conventional or CNC machine tool turning it into a gundrilling machine. 

The system is fed via the shops compressed air line and mixes the air with the cutting oil from the integral reservoir and then supplies a timed pulsed mix to the drill. The air evacuates the chips while the minimal oil supply lubricates the carbide during the drilling process. 

The oil reservoir has a magnetic base for ease of positioning within the machine and the system has a manual control for the mixture ratio and timed pulse rate. 

Morse taper and straight shank holders are available with a Ø25mm bore to accept gundrill drivers.
