Greenlee is an American industrial and electrical tool company headquartered in Rockford, Illinois. It was founded in 1862 by twin brothers Robert L. and Ralph S. Greenlee to manufacture their invention called a hollow chisel mortiser, consisting of a drill surrounded by four chisel blades used in making mortises (the hole) for mortise and tenon joints, for the furniture industry in Rockford.[1] While no longer produced by Greenlee, hollow chisel mortisers are still used in cabinetmaking today from a variety of other manufacturer. The brothers later diversified into a variety of hand woodworking tools as well as machinery for making wooden barrels.
The company was acquired by Detroit-based Ex-Cell-O Corporation in 1969.[1] Industrial conglomerate Textron acquired Greenlee as part of its acquisition of Ex-Cell-O and its subsidiaries in 1986.[2] Greenlee purchased Fairmont Hydraulics in 1992 and German tool manufacturer Klauke in 1996. Greenlee expanded into data/telecommunications equipment with the acquisition of several companies in 1999 and 2000 which now fall under the Greenlee Communications brand. Greenlee expanded its DIY offering with the addition of Paladin Tools on December 17, 2007.
