Jonesville Tool & Manufacturing began in 1988 as a general tool shop, designing and building tooling and gauging for local companies. We then progressed into special machine building and CNC rebuilding and retrofitting; now, more than 28 years later, we are a world-class precision contract manufacturer of CNC machined products, covering a wide range of customers around the globe.

JTM now boasts over 50 CNC spindles, from knee mills to 60 hp auto-load twin spindle lathes. We have the right equipment to efficiently produce a wide range of products for the HVAC, heavy truck, agriculture, military, automotive, commercial, medical and marine industries – and others. With an average employee tenor of over 10 years, and a “core group” of employees with over 15 years each on staff, we have the experience and knowledge to complete the most difficult projects on time, with quality that meets or exceeds our customers’ expectations every time.


With Jonesville Tool & Manufacturing, we offer our clients something that one can’t put a price on – unsurpassed customer service stemming from honesty in our interactions, and an attitude of servanthood. When we say that we are going to do something, you can count on us to do it, and not to stop until you are satisfied. Also, we are here to serve each client to the best of our abilities, meeting your unique needs.

We are proud to offer our clients all the benefits of “global manufacturing,” along with our ability and desire to work with our customers’ engineering teams to improve efficiencies, eliminate problems and improve durability and performance. Operating under the principles of lean six sigma manufacturing, we are able to provide competitive quotes.

JTM is committed to sustainability, and we have well established recycling programs encompassing many materials that we encounter and use in our trade, including gloves, cardboard, chips, shavings and machine coolant.
