Sirois Tool to celebrate 60 years in business in 2020

Back in 1960, Robert Sirois started a business manufacturing cutting tools, and he soon expanded to offer precision tooling for the bearing industry. We’ve certainly come a long way in terms of our technology and products since then, but we’ve remained committed to the Sirois legacy of high quality and reliable service—and next year, we’ll be proud to mark 60 years of success and growth.

Today, our 25,000 square foot facility houses advanced machining technology both for Sirois Tool and the Dow-Gage product line for precision gage manufacturing, a line we purchased in 2005.

Our expansion continued in 2012 when we purchased the assets of All Five Tool and North American Spring Tool. North American Spring Tool operates as a separate division that provides a complete line of carbide and steel tooling for the spring coiling industry.

Our high-quality products are made by our experienced, highly skilled Toolmakers and Machinists whose commitment, experience, and expertise deliver every time. As a Lean Manufacturer, we aim to continually lower our costs and shorten our lead times, providing our customers with the best possible service and product. We are always looking for innovative ways to improve.

As we celebrate our 60th anniversary, Sirois Tool continues to add equipment, capabilities and capacities, and even more importantly, train all our employees, especially our apprentices and others new to our industry. We thank all of our customers for contributing to our long-term success, and we look forward to serving you in the years to come!


In an effort to better serve our customers’ requirements, Sirois Tool has purchased a new Haas DS-30Y. This Y-axis turning center combines dual-spindle turning with Y axis, C axis, and live tooling to create a powerful machining solution. Off-center milling, drilling, and tapping operations are possible for increased machining capabilities.

The DS-30Y has a 12-station BMT65 turret and synchronized C axis for versatile 4-axis capability. The opposed spindles support fully synchronized turning, and allow on-the-fly part pass-off to reduce cycle times. All this adds up to more efficient precision parts production, lower costs and shorter lead times for the appropriate parts.

We have also completely updated the layout of our CNC Lathe department to be more efficient. This new layout leaves room to add more equipment as needed to best serve our customers. Our CNC Lathe department also includes:

  • MAZAK QTS 300M CNC Turn/Mill with a 12″ chuck and up to 3.0″ bar size through the chuck and live milling tools for on center milling operations such as flats, cross holes and face holes.
  • *HAAS ST25Y CNC Turn/Mill with a 10″ chuck and up to 3″ bar size through the chuck with a Y-axis and a 12-station turret with high-torque live tooling C axis
  • *HAAS ST25 CNC Turning Center with a 10″ chuck and up to 3″ bar size through the chuck

Like all of the tools, gages, precision-machined parts and assemblies made by Sirois Tool, the DS-30Y is Made in the USA. For more information on how Sirois Tool can assist you with your tooling needs contact us at (860) 828-5327.

At Sirois Tool, we truly believe that our employees are critical to the success of the company. Without them, nothing happens! Therefore we try our best to make them feel appreciated. One way we do this is with our benefits package.

Not only do we offer competitive salaries, but our complete benefits package is one of the best available. To start, we have a free medical, vision and dental plan. This is highly unusual in this day in age. From there, we also offer a 401k, with a company match and profit sharing. Finally, we provide tuition reimbursement.

In addition to salary and benefits, we realize that our employees also need a career path and job fulfillment. It is imperative that we provide this especially to people who are just starting out. Therefore, another way to show our appreciation is through praise for individual accomplishments.

This was demonstrated last week when we had a celebration for one of our apprentices. Kyle completed his Apprenticeship hours in February. The Connecticut State DOL issued him a Certificate of Completion, which we presented to him. To further celebrate his accomplishment, we gave him a Gerstner Tool Box.

Kyle graduated from the Manufacturing Technology Program at Vinal Tech in Middletown. He came to Sirois Tool because we were willing to put him into a state approved Apprenticeship program. We will continue to participate in this program in the future, especially if they can introduce us to students like Kyle.

Zeiss Contura, powered by CALYPSO, is the accurate, flexible solution we needed

Working with customers across a variety of industries, from Aerospace to Firearms, the one common necessity is accuracy. In an effort to continue providing service beyond our customers’ requirements, we are continuously looking for ways to improve our own processes. One such improvement was the investment in a CMM (coordinate measuring machine).

When sourcing a CMM, our top priority was to find a flexible system that offered reliable and repeatable measurement along with scanning capabilities for different products. We selected the Zeiss Contura CMM because of its outstanding capacity to adapt to a variety of applications, along with the added measurement and scanning technology provided by its CALYPSO CAD-based measuring software. CALYPSO can import STEP customer models of products, so we are able to provide accurate inspection data right from the model.

This CMM allows us to automate inspection processes while speeding up throughput on more complex inspections. Its fixed passive sensor also allows for single-point measurements of features. Zeiss CALYPSO software enables us to perform almost any measuring task. Additionally, CALYPSO’s planner package allows offline programming and inspection simulation to be performed, which saves time and helps to avoid costly CMM crashes.  

Another side benefit to using this CMM for inspection is that we are able to import the data collected directly to IM Pro, our inspection management software. The IM Pro facilitates the collection of measurement results from the CMM, enabling retrieval of the measurement data in real time. This not only saves us time, but it also improves the accuracy of the inspection reports. 

Zeiss Industrial Metrology is a leader in CNC coordinate measuring machines and complete solutions for multidimensional metrology both in the lab and in production. We’re proud to align with Zeiss for our industrial metrology needs, and we are confident that their products will provide us with dependable, accurate inspections for many years to come.

Sirois Tool continues to add equipment capabilities and capacities, and even more importantly, train all employees, especially apprentices and others new to the Industry. This enables Sirois Tool to keep up with customer requirements for tooling, gages and precision machine parts and assemblies.

As manufacturers we know that investing in our future workforce is critical to our success. It’s not enough to find the next employee. We must be committed to promoting careers in manufacturing with every chance we get.

Recently, we were approached by Vinal Tech to create a video in conjunction with CPTV’s Making the Future. It would star one of our apprentices. We saw this as a great opportunity to promote manufacturing. It also highlighted our business and gave our intern great pride in what he’s doing.

As you see, Ian talks about the benefits of a career in manufacturing. He talked about the training he’s getting at Vinal Tech and how it translates to his internship. Most importantly, he shares his plans to continue his education and work towards a specific career goal. A path for success is critical to the next generation of workers.

This is also a great recruitment tool as it helps to promote Sirois Tool. Ian talks about how much he enjoys working with Hugh and the benefits Sirois Tool offers. Our focus is a work environment that is a pleasure to come to and a benefits package that shows our employees how much they are valued. Ian does a nice job of demonstrating our mission.

I know that as manufacturers we are typically hesitant to share information, concerned that it will be used to take business or in more recent years, employees from us. This is something we need to change if we’re to address the workforce shortage. The challenge will not change until we change our approach to it.
