Gun Drilling

Precision Gun Drilling and Deep Hole Drilling in Wisconsin

At MRS Machining, we provide precision gun drilling services for deep hole drilling applications that require accuracy, straightness, and tight tolerances. Our team specializes in producing complex machined parts with deep bores, delivering consistent results across low-volume and short-run production. Based in Augusta, WI, we serve customers throughout Eau Claire, Chippewa Falls, and surrounding areas.

Gun drilling is ideal for applications where traditional drilling methods cannot achieve the required depth-to-diameter ratio, surface finish, or precision.

Gun Drilling Capabilities

Our gun drilling services support a wide range of deep hole drilling applications, including:

  • Deep hole drilling with high depth-to-diameter ratios

  • Precision straightness and alignment

  • Tight tolerance internal diameters

  • Smooth internal surface finishes

  • Drilling in a variety of metals including steel, stainless steel, and aluminum

  • Consistent results across short-run and low-volume production

Integrated with Precision CNC Machining

Because gun drilling is performed alongside our precision CNC machining services, we can streamline production and reduce handling. This allows us to deliver fully machined components with deep hole features completed in-house. Our deep hole drilling services are ideal for applications requiring high accuracy and consistent internal bores. We can support your next project with efficient workflows, reduced lead times, and consistent machining processes.

Value Added Services

Gun drilling is one part of our full-service CNC machining approach. MRS Machining also offers value-added services including laser marking, surface finishing, heat treating, plating, assembly, tag and bag, and custom packaging.

What is gun drilling?

Gun drilling is a deep hole drilling process used to create straight, precise holes with tight tolerances. It is ideal for applications that require high accuracy, smooth internal finishes, and consistent results.

How deep can gun drilling go?

Gun drilling can produce holes many times deeper than their diameter while maintaining straightness and accuracy. This makes it ideal for components that require long, precise internal bores.

What materials can be gun drilled?

Gun drilling works with a wide range of materials including steel, stainless steel, aluminum, and other metals commonly used in precision machining applications.

What is gun drilling used for?

Gun drilling is used for applications such as hydraulic components, shafts, tooling, and other parts that require deep, straight holes with tight tolerances.
