About Us

Thompson Grinders was established in 1964 by Thomas “Woody” Thompson in Watertown, Wisconsin. The business was purchased in 1980 by Gary Pillard and has since been growing and improving to meet the changing needs of today’s machining & tooling industry.

Thompson Grinders is currently manufacturing, sharpening, repairing and modifying tooling for companies throughout the continental US. We offer pick up and delivery service in Wisconsin and northern Illinois.

We have a wide range of CNC tool and cutter grinders to meet our customer’s growing needs. Along with superior sharpening capabilities, our CNC machines have custom production cycles that will generate new tools with precision, consistency and repeatability!
