Company History

William Booth Gammons: Founder

The GAMMONS® Hoaglund Company was started by William Booth Gammons in 1918. From an early age, William Gammons was very intrigued by machinery and through his curiosity he learned to execute new ideas and build different types of machines. He worked for numerous manufacturing companies, such as Dwight Slate Machinery Company of Hartford, Pratt & Whitney, Fenn Manufacturing Company and Colts Patent Firearms Manufacturing Company, where he honed his machining skills.


William Gammons became a respected inventor in his day, as a machinist, he invented the intermittent alarm clock and an automatic money changing machine. He perfected the Gammons (Helical) Taper Pin Reamer, for which he received a patent, and would become the main product of his new reamer manufacturing company. He received many patents for his inventions including the Parob Reamer, Gammons Expansion Reamer and a broaching machine. 


William Gammons worked as a foreman at Pratt & Whitney when he invented the Helical reamer. He tried to sell the tool to P&W, but they rejected Williams plan as being too "revolutionary". His luck changed when one of the directors encouraged him to start a business and with proper guidance, instructed William on business procedures.


William Gammons and his wife, Susannah, sold their house and with their life savings started their own manufacturing company.


In 1920, William Gammons, Charles William Holman and H.O. Bowers partnered to form the Gammons-Holman Company. Their helical reamers were used both nationally and internationally during WWII. Gammons supplied the allied forces with reamers to be used in airplanes and radios.


Charles William Holman


William always believed in fairness, hard work and community. He gave both men and women jobs at the factory. Each worker would receive a quarterly check, in addition to their regular salary, because William believed in profit sharing and equality.  




In 1932, William Gammons died and his wife, Susannah Gammons, became President. She bought Mr. Holman's company shares, and decided to partner with C. Arthur Hoaglund, a tool engineer that had worked with her husband, to form Gammons Hoaglund. Susannah Gammons remained President until she passed away in 1940. Her daughter, Marion Booth Gammons was the general manager of the company during this time and then became president until the company was sold in 1966.

Joseph Brescia purchased The Gammons Hoaglund Company in 1966 and ran the business until it was subsequently sold to Paul Stefanik Jr. in 1984. Mr. Stefanik then purchased the Buol Machine Company- a New Britain, Connecticut based reamer manufacturer and combined both companies in East Hartford, Connecticut. Paul's son Paul Stefanik III purchased the company from his father in 1990, returned it to Manchester Connecticut and has expanded the manufacturing company by investing in CNC equipment and acquiring the William E. Kraus Company and East Coast Precision Grinding. He merged all these companies under the GAMMONS® Hoaglund Company trademark.

Manchester Historical Society: William Booth Gammons







"We tried other reamers, but we got buried in scrap. The cheap reamers ended up costing us much more than the Gammons' reamers. We went right back to Gammons."

Richard Zelles
Vice President
Magni-Bal Corporation

"We have to hold tolerances and angles that other companies won't touch. Gammons custom work is superb. Their reamers can't be matched. They last longer. Hold the edge better. They let us give our customers products with a precision finish. Products we're proud of."

Brad Harken, Purchasing
Blackhawk Engineering

"Our products are clear acrylic, and finish is everything. We just won't consider anything but a Gammons Hoaglund reamer."
