Gun Drilling

Gun Drills (through coolant drills) are straight fluted drills which allow cutting fluid (either compressed air or a suitable liquid) to be injected through the drill’s hollow body to the cutting face. They are used for deep drilling. A depth-to-diameter ratio of 300:1 or more is possible.
