Since 1923, the Rottler name has been synonymous with leading edge technology. In those early days, “high-tech” meant non-powered portable boring bars, but unsurpassed research and attention to the needs of the American engine rebuilding market has allowed the Rottler family to refine – and redefine – the standard in rebuilding equipment.

Today, Rottler Manufacturing offers a complete range of machines for every type of engine builder, whether you have a custom one-man machine shop, a diesel jobber shop or a demanding production remanufacturing facility. And when we say that Rottler has a machine designed specifically for your application, we mean it. Rottler equipment is not built to be warehoused for some potential future sale; each piece is custom-built to the exacting standards demanded by the most accurate machining companies in the world. Located in Kent (near Seattle), Washington, U.S.A., Rottler maintains the largest domestic facility 100% dedicated to the automotive aftermarket. Rottler’s manufacturing facility boasts the finest equipment available for maximizing the precision componentry used in our machines. This commitment to quality keeps Rottler Manufacturing on the cutting edge and ensures that what we sell will help you sell. Designed and built to last using the best equipment and materials, assembled by dedicated professionals, you can be sure that your Rottler machine will meet your needs today and into the future. New 3D design systems are improving prototype development. We have installed the first Okuma seven-axis fully automated CNC machining center in the Northwest and plan to expand our facilities to continue to accommodate new equipment and bring products current in research and development to market. And many of the processes used in the construction of our equipment are accomplished using Rottler machines – not only do we sell them, we use them! Rottler manufactures a variety of accessory tooling designed to make jobs easier and faster. Rottler has developed tooling to allow the job shop or performance shop to quickly produce precision surfaces on odd jobs competitors must turn away. The same capability applies to the production machine shop where the increasing demand for quality now requires finishing surfaces previously left unmachined.

With the in-house capability of quality control, each part is inspected prior to shipment. This assures our customers the highest standard of quality. Having the ability to engineer, manufacture, assemble and stock machinery makes us responsive to the dynamic changes that we are constantly faced with in the industry.

Yet despite the technological leaps, it still comes down to one simple fact – the investment you make isn’t only in money…it’s in trust. Our dedicated team of experts can help you find the machine you need for your market. Your name is on the line with each engine you produce, so be sure that our name is on your machine.
