About Us

Stromberg Tool is a family owned and operated company

We've been in business for three generations and over 50 years.

Started in 1958 by Ivan Stromberg in the town of Clinton, MA, Stromberg Tool grew and in 1977, we moved to our current 13,000 square foot manufacturing facility in Sterling, MA. Then in 1981 we purchased our first CNC turning machine and there was no looking back.

Today, Stromberg Tool is still owned and operated by the Stromberg family. All manufacturing is completed at our state-of-the-art facility located in Sterling, Massachusetts. Precision tolerances, exacting workmanship, and rigorous quality control systems are part of each step in the production process. Every workstation is equipped with tenth micrometers and electronic drop indicators. In addition, a bar code tracking system maintains complete traceability for each and every process.

Our highly skilled workforce put customer service first by working to solve problems, improve quality and refine processes. Whether we are servicing customers locally or worldwide, our unmatched quality and quest for continuous improvement ensure ever-improving processes.
