IGA Abrasives is a U.S. manufacturer, supplying the North American market with precision grinding wheels and honing products. Known since 1959 for excellent quality. IGA Abrasives was founded in 1955 by Donald Kranenberg, Sr. Mr. Kranenberg, a Purchasing Manager at a large automotive parts supplier, saw a need for an abrasive producer, specializing in internal grinding wheels. The company developed a manufacturing process and a specification system which resulted in a highly-automated manufacturing system to produce large volumes of grinding wheels, and later in 1964, honing and dressing products.
