Information on McCrosky Tool Corp. initially came from a 1947 advertising calendar seen on eBay. It stated that they were designers and manufacturers of Jack-Lock milling cutters, Super Adjustable reamers, block-type boring bars, turret tool posts, Wizard quick-change chucks, and special multiple operation tools. They were incorporated in 1907 as McCrosky Reamer Co. In 1920 they purchased the assets of Davenport Manufacturing Co. and began producing Davenport's hand and power milling machines.
