Keller Manufacturing Co. dates back to 1924, when the first power hack saw was manufactured. At one point they were located at 1428 Cliff Road, Burnsville MN 55337, with another plant in Eau Claire, WI.

In 1978 they were Keller Manufacturing, Division of Sales Service Machine Tool Co., 3150 Mike Collins Drive, St. Paul.

The Keller business was sold around 2004 and is now known as Keller Industries, 828 Dunavant Road, Leeds AL 35094. They currently make updated versions of the original power hack saws.

Sometime in 2011 or early 2012 Keller Industries closed--support is no longer available.

Serial number data point: Machine #13580 was built in January 1975.

Additional information from George Booth (son of George Booth Sr.-former president of Keller): For most of it's life Keller was solely made in EuClare Wisconsin at 601 Jefferson Street. The address was where the name came from for the smallest of the saws referred as the "jeff" and the largest was the number 5 a 10x10 inch capacity. The factory was owned and operated by Ole Paulson who also did all of the design work. They sold a die filer and added a band saw to the line in the early 70's outsourced Wells Mfg. in Three Rivers Michigan. Stephen Havier headed Keller for most of it's life. Havier was President of Sales Service Machine Tools, Keller President was my Father George Booth Sr. I worked for the company for a short time in the seventies. The head office was 2363 University Avenue in Saint Paul Minnesota. Some Keller trivia: The Turkish Highway Department bought 60 of the model 3C, The Navy was big customer and a 3C was believed to having cut the first rocks from the Moon.
