The working theory of gun drill is that the cutting fluid is injected through the inside cooling channel of the tool to the cutting face, then the cutting fluid and cutting chips flush out from the V-shaped flute, which formed between the hole and the drill shank. And the cutting fluid also provides lubrication for the drill periphery.
In deep-hole drilling, the inside coolant holes are available in the following types according to the tool dimension and the flow requirements.
kidney-shaped hole(Φ 2~8 mm)
double hole(Φ 8~40 mm)
single hole(Φ 5~40 mm)
