Deep Hole Gun Drilling


Deep hole drilling was first developed for the manufacturing of firearms, hence the name gun drilling. Originally a time-consuming and costly process, today's technological advances make it a highly efficient manufacturing operation in all metal cutting industries including automotive, aircraft and aerospace, construction, medical, mold and tool and die, hydraulics, pneumatics, and more.

Gun drilling is an ideal solution for most deep and precision drilling projects. This high precision operation produces accurate, repeatable holes, with excellent surface finishes. Gun drills hold location to precise tolerances, are sized to exact specifications, produce burr free holes, and can be formed to produce specific shapes in blind holes with minimal machine adaptation.
