Born in America's Industrial Heartland. Trusted across every era of manufacturing.
Founded in 1974 by Ingersoll Rand veterans Jack Grace and Ed Hoyle, Ohio Tool Systems has bridged legacy systems and future-ready solutions for more than five decades.
Our brand narrative
Five decades of growth, unified under one banner.
What began in 1974 as Ohio Tool Systems has grown through deliberate acquisitions and internal expansions into a single, integrated engineering partner. Each chapter broadened our service reach, deepened our technical bench, and brought new specialists onto the floor — all now unified under the OTS brand.
