Greenlee is an American industrial and electrical tool company headquartered in Rockford, Illinois. It was founded in 1862 by brothers Robert and Ralph Greenlee to manufacture their invention, a drill surrounded by four chisel blades, used in making the pockets for a mortise and tenon joint, for the furniture industry in Rockford. This device is still used in cabinetmaking. The brothers later diversified into a variety of hand woodworking tools as well as machinery for making wooden barrels. The company was acquired by Textron in 1986. 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 b
