Customers count on us at Brewster Washers for the manufacturing of precision custom parts that benefit a wide variety of applications.

Our EDM machinery can accommodate work pieces measuring up to 12″ in length, thicknesses measuring from .001″ to 9″, and a minimum diameter as small as .050″.

Our EDM services manufacturing process allows us to create specialty-shaped metal parts of various sizes, while still maintaining the same high-quality standards our customers have come to expect, and the tight tolerances required.

When a project calls for a shape, tolerance, or thickness that doesn’t exist in a standard catalog, custom precision parts are the only way to move forward without redesigning around a limitation. Our EDM process is built for exactly that scenario. Rather than starting from stock tooling, we manufacture directly from your blueprint, so the part matches your application instead of the other way around. That approach is what makes it possible to hold tight tolerances on specialty geometries, whether you’re sourcing a single prototype or a full production run.
