About Us

Keystone Machine & Manufacturing strives to provide quality products to better the interests of customers and end use customers. We produce a diverse array of machined products, varied in complexity, across multiple industries. All KMM products are American made in Waterford, PA.

Our Shop

Our shop is located at 549 PA-97 Waterford, PA inside a government built, underground bunker developed during the Cold War Era. These bunkers were built every 150 miles across the country to service a (now defunct) AT&T line for critical communications. We aimed to preserve as much of the original design and mementos that made this bunker so unique. We are surrounded by 3 foot of concrete on all sides and are able to support a full semi parking on our roof!

We specialize in Swiss Lathe machining and have a Tsugami BO326-III and a S205-II giving us the capability to run up to 1.5” DIA bar.

Our Focus

KMM strives to maintain a high level of customer satisfaction and delivering the highest quality product possible. With our excellent team of employees, we believe no task is unachievable.
