Born as a basement job shop in Euclid in 1966, JM Performance Products now manufactures milling-machine optimization products in Fairport Harbor, led by its patented High Torque retention knobs. Founder John Stoneback developed the design to address toolholder expansion in V-Flange tooling, and the company later added its patented Taper Shank Test Fixture. Formerly J&M Machine, the company adopted the JM Performance Products name in 2013 as it shifted from defense-oriented precision job work to its own product line.
