Precision Gun Drilling

At Midwest Precision Manufacturing, we provide deep hole gun drilling services ranging in diameters from .062″ – 2.00″ in a wide range of materials. We are experienced in drilling both standard and exotic 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 30,000-square-foot manufacturing facility is set up with versatility in mind, allowing us to competitively manufacture specialty deep hole gun drilling work as well as high volume production.

In addition to gun drilling, we offer additional deep hole boring & honing services, 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 in between.
