Sirois Tool Co., Inc.

Please note: October 4, 2024 if fully scheduled but if you contact us we are open to hosting a tour of our facility on another Friday in October in celebration Manufacturing Day. Sirois Tool continues to operate as a traditional Tool and Gage Room with skilled Tool and Gage makers, and Apprentices. While manufacturing of Precision Parts and Subassemblies is a growing part of our business, we believe that having the Tool and Gage manufacturing capabilities in house allows us to better serve our customers. With our Precision Grinding and WEDM/EDM Capabilities, in addition to our Milling and Turning capabilities, we can provide a more complete solution for ALL of our customers. Sirois Tool Co., Inc. was started in 1960 by Robert Sirois. Originally, the company specialized in cutting tools for Pratt & Whitney Aircraft and other companies. In the late 1960’s the company started making tooling for the bearing industry. First making cutting tools for screw machines and later making tooling for grinding and other operations. In 1972 the company was purchased by three long-time employees who built the company into a strong, diversified, manufacturer of precision tooling, gages and parts for many industries. Ownership of the company has continued to pass to other long-time employees.
