Greenlee

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 for mortise and tenon joints, for the furniture industry in Rockford. 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.
