About Seller: Founded in 1903, National Machine Tool Company offers nearly a century of expertise in the development and production of precision internal keyseating and oilgrooving miller equipment. With a team of skilled Cincinnati craftsmen, National delivers the metalworking industry's most competitive tools in the internal slotting sector. Designed to mill straight, precise, and uniform internal key and oil slots in various bore diameters and materials, National keyseating and oilgrooving millers are capable of completing slots in one pass through the workpiece bore. Unlike other key-slotting equipment, National Millers can operate in open end or blind bores, producing slots with accuracy and appearance comparable to those made by traditional horizontal milling machines. These millers are user-friendly and require minimal setup time, featuring a straight shank for direct use in a standard drill press chuck. They are compatible with most types of drill presses, radial drills, machining centers, vertical mills, and CNC equipment, with the option to fit different tool holding systems. National millers come in a wide range of sizes to meet the slotting needs of the metalworking industry, offering solutions to various slotting challenges at competitive prices. Whether for open or closed-end bores, National millers can efficiently handle internal keyseating and oilgrooving tasks with precision and reliability.
