Gun drilling is a precision deep hole drilling process that use a long, straight tool to produce extremely deep holes in variety of materials. This tool has a unique head geometry, a standard gun drill has a single effective cutting edge, and a groove along the length of the tool. A gun drill cuts with coolant that is introduced through a hole in the tool, and exhausts chips through the groove. Additionally, guide pads on the tool head work to burnish the hole while drilling, resulting in an extremely round hole with a precision diameter. This internal coolant/external exhaust feature distinguishes gun drilling from other deep hole drilling methods.

Gun drilling represents a advanced and high effective hole drilling technology. Not only used for drilling deep hole(length and diameter ratio >10), but also for drilling precise shallow hole. Gun drill is main tool for gun drilling. It is welded drill shank, drill stem and drill tip together, with a through-hole by which the cutting liquid enters cutting area.
