In 1876 W. L. Covel of Chicago was making saw-sharpening machines. In 1886 Milo Covel of Chicago was manufacturing the Kinney patent saw swage. In 1890, Milo Covel and Lars Larsen Filstrup founded Covel Manufacturing Co. to make saw sharpening machinery. By the late 1890s the company president was Henry P. Schofield, with Filstrup as secretary and treasurer. Filstrup and his family bought out Covel's remaining interrest in 1904 and three years later relocated the business to Benton Harbor, Michigan.

In 1916 The Machinery Company of America was established in Grand Rapids to act as distributor for Covel Manufacturing Co., Hanchett Swage Works, and Baldwin, Tuthill & Bolton. In late 1927 The Machinery Company of America changed its name to the Covel-Hanchett Company, and in January 1928 merged with Wilmarth & Morman Co., with the merged concern using the Covel-Hanchett name. In July of 1928 Covel-Hanchett acquired the Badger Tool Co., of Beloit, Wisconsin, makers of disk-grinding machines.

In 1945 it was announced that the Covel-Hanchett Company was purchased by the Hanchett Manufacturing Company of Big Rapids. In 1968, Covel Manufacturing Co. was acquired by Atlas Press Co. of Kalamazoo, which changed its name only a year later to Clausing Corp.

Besides saw sharpening machinery, Covel Manufacturing Co. made power hacksaws that were sold under their Excel Machine Tools subsidiary and through Sears, Roebuck & Co. as Craftsman brand, with model-number prefix 108.
