Sirois Tool Co., Inc.

Sirois Tool Co., Inc. was founded in 1960 by Robert Sirois as a manufacturer of cutting tools, and quickly moved to precision tooling manufacturing for the bearing industry, including low-volume machine parts and assemblies. Today’s owners continue to build upon the Sirois legacy of high quality products, reasonable lead times, and delivery as promised.

Our modern, 25,000 square foot facility houses the most advanced machining technology for Sirois Tool, as well as the Dow-Gage product line for precision gage manufacturing, purchased in 2005.

In December 2012 Sirois Tool purchased the assets of All Five Tool and North American Spring Tool. All Five Tool has been incorporated into the Sirois Tool product line. North American Spring Tool remains a separate company that provides a complete line of carbide and steel tooling for the spring industry.
