Our History

After serving in the military in WWII, Thomas “Woody” Thompson started working in the tool grinding department at Allis Chalmers in West Allis Wisconsin.  In 1964 he left Allis Chalmers with the desire to start his own grinding and resharpening business. That year he found a place of his own in Watertown, Wisconsin where Thompson Grinders Inc. was created. 

After 5 years in Watertown, Thompson Grinders spent the next decade in Wales, WI. Woody realized he needed a bigger space of his own to expand. In early 1979, he moved the business to its present location in Ixonia, WI. Thompson Grinders was purchased in 1981 by Woody’s nephew Gary Pillard where he continued to grow and expand the company. Gary eventually brought on his three sons Paul, Seth and Ross, to help with improving and meeting the changing needs of today’s machining & tooling industry.
