Quality Is Our Legacy

In 1913, L.H. Hamilton and Chester H. Beach laid the foundation for a new company with the goal of producing labor-saving, motor-driven electrical devices. They envisioned products built with better designs and better components than competition of the day.

The original company was called the Wisconsin Electric Company, but it soon became Dumore Corporation.

Dumore Corporation thrived, refining its motors and bringing together a management / employee team dedicated to building quality products and standing behind them. The high-quality electric motors soon became part of better industrial tools.

Now organized as Dumore Motors, Dumore Tools and Dumore Specialty Products, the tradition of turning creative ideas into high-quality products continues, and our founding principles remain the same and are still what drive Dumore today:

  • Dedicated to the highest quality products and standing behind them
  • Anticipate and respond to customer needs to exceed their expectations
  • Invest in a dedicated and capable team, equipped with the latest technology, committed to seeking innovative solutions
