The Introduction of Cemented Tungsten Carbide Gun Drill Blanks
Gun drilling, invented in Europe more than two centuries ago, is the process of drilling deep, straight holes in a variety of metal alloys. It was first invented in order to make long, straight gun barrels, hence the name gun drilling.

The gundrilling process and tooling have been refined for maximum performance and use on modern, dedicated machinery. Firearms continue to be a common application for gundrilling. Other industries include diesel fuel components, medical tooling, plastic injection molds, and more.
