Gun Drilling


Cliff Industrial is a West Wisconsin leader in gun drilling services.

Our gun drilling services range in diameters from .062″ – 2.00″ in a wide range of materials including aluminum, steel, cast iron, graphite, and plastics. Multiple hole types can be drilled into plastic injection molds and other large work pieces. Angle, blind, offset, and cross cavity holes can be drilled up to 240″ in depth, holding tolerances of 0.001″ of drift per inch of drilling. Our manufacturing facility is set up with versatility in mind, allowing us to competitively manufacture specialty work as well as high volume production.

In addition to gun drilling, additional deep hole drilling processes, including BTA/STS drilling, counterboring, and trepanning can be used to create larger holes up to 10″ diameter. Honing can further refine surface finishes to create high precision parts. We serve a range of industries from plastic injection mold makers to oil field exploration companies and a wide variety of manufacturers. Turnaround times are typically very fast, with expedited services available as needed.
