" I have worked with Dumbarton Tool for the last 10 years on my specialty cutting tools. In working with Dumbarton they have provided me with quality and service for my customers Briggs & Stratton and Chrysler Corporation. 

Dumbarton Tool has allowed me to provide many cost savings to these customers by reducing their production cost and making higher quality products.

They have lead the way in performance, technology and deliveries giving me a higher rate of success at these manufactures.

My motto is: There are many people that can save you a dollar, use the people that don't cost you a dollar! "
