Product  Description

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.

Coolant holes(Standard)




kidney-shaped hole(Φ 2~8 mm)

double hole(Φ 8~40 mm)

single hole(Φ 5~40  mm)
