Our Name Says it All.

Rapid Precision Manufacturing provides precision machining services with strict adherence to quality and quick turnaround.

A Quarter Century of Excellence

Rapid Precision Machining was founded in 1997 in Britton, South Dakota, by David Koeppe and Lars Lyngaas. David and Lars started the company to provide contract precision CNC turning and milling services to those needing precision manufacturing.

Our first projects consisted of turning parts on Haas and Hyundai CNC turning equipment and milling parts on Haas CNC milling equipment. As our company has grown, we’ve sought new challenges and invested in new technologies, ultimately expanding into Swiss turning, Multi-Axis machining, and Horizontal milling services. This has helped us to become a more well-rounded, single-source manufacturing company.


RPM specializes in CNC turning and Swiss turning with a secondary focus on milling operations. Our ideal project entails medium to high complexity machining work with 2,500 to 5,000 parts weekly.

Typical Projects, Outstanding Results

Our typical clients come from several industries, from automotive to industrial, sporting goods to firearms, and beyond. Typical projects include machined components for clutches, filters, fittings, firearms, bolts, spacers, and industrial lift components. However, we are open to discussing any manufacturing project you might have.

RPM has the technical and operational expertise to handle a wide array of lengths, widths, heights, weights, thicknesses, tolerances, and die clearances with production capacities from 1 to 100,000 units.

Consistency and Delivery

You deserve consistency in quality, pricing, and delivery. Considering the many manufacturing options in the marketplace, finding a company to deliver that should be easybut that’s not always the case. Our customers regularly share stories of missed deadlines, high rejection rates, and unpredictable pricing. But you don’t have to settle.

RPM, Inc. is committed to quality for the benefit of all stakeholders and strives for customer satisfaction through innovation, continuous process improvement, and the development of our valued team members. We provide exceptional service throughout the development process, from planning to prototype and setup to production.

A Quality Mission

From the beginning, we’ve made it our mission to provide quality production CNC machining services to companies seeking a long-term manufacturing partner. We continuously invest in cutting-edge machining technologies, educate and empower our employees, and reward excellence (exemplified by two decades of continuous ISO 9001 certification).

Over the past 25 years, we’ve enjoyed a return rate of less than 1% and a reputation for excellence that accompanies such an impressive statistic.
