gun drilling
Gun drilling is a process that produces deep, straight holes in a variety of materials. A gundrill tool differs from a conventional twist drill by its unique head geometry; a standard gundrill has a single effective cutting edge. Guide pads burnish the hole while drilling, allowing the hole to maintain straightness. The result of this burnishing activity is a very round hole with a precision diameter.

Gun drilling was initially developed for drilling gun barrels. Armament manufacturing continues to be a common use of this process. Other common industries include energy, oil and gas exploration, engines, diesel fuel components, and plastic injection molds.
