What is Gun Drilling?

At KGD Aerospace Manufacturing, one of our main capabilities is gun drilling. In fact, we were originally known as Kansas Gun Drilling because of a focus on machined parts, particularly via gun drilling. However, we are often asked what gun drilling means?

Gun drilling is a process that produces deep, straight holes in a variety of materials. A gun drill tool differs from a conventional twist drill by its unique head geometry; a standard gun drill 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.
