Herkimer Tool & Machining Corporation was established in 1921. In the beginning, Herkimer was engaged in sub-contract machining work specializing in the production of bearings for the transportation industry. The founders set up shop in the city of Herkimer, NY, a prime upstate location west of Albany. Access to excellent transportation contributed to Herkimer's successful longevity. The Mohawk River, Erie Canal, New York Central Railroad's mainline to Chicago and the New York State Thruway all are within a few blocks of the plant.

In 1929 the "OK Model Airplane Engine" was designed and developed. After the depression this engine was put into production. Today this high quality model engine remains very popular, especially among collectors. During World War II, Herkimer Tool & Model Works produced thousands of small gasoline engines for our Armed Forces. These engines were installed on drone aircraft for decoy and target applications. After the war, Herkimer returned to subcontract machining and production of the model airplane engines ended for a while in 1965.

In 1960 the plant relocated across town to the current address. The sub-contract machining business was growing and the factory expanded three times since then. In 1973, Ellis Green purchased the business and changed the name to Herkimer Tool and Machining Corp. and reinstated production of the HO 1/87th Scale model railroad cars under the "OK" trade name. Herkimer produced these fine quality model railroad passenger cars until the division was sold in 1997 back to the grandson of the founder who also resumed production of some of the gas engines.

Ellis's son, Frank Green joined the company in 1976 and continues today as President. Ellis passed away in 2007. Herkimer has been a private held family business for nearly 90 years.

Herkimer Tool and Machining has been engaged in the sub-contract machining business for over 75 years. Production consists of Brown & Sharpe Screw Machining, Hardinge CNC turning, Centerless Grinding, Milling, Drilling, Punch Press work and a number of specialized machining techniques to produce parts to customer specifications. Herkimer Tool utilizes conventional and the latest CNC machining methods to maintain a balance of precision, quality and competitive prices.
