  • Tool for chip removing machining and having fluid-conducting branch ducts
    Patent number: 6595727
    Abstract: A milling tool includes a rotary cutting head having an end surface in which grooves are formed. The grooves communicate with a duct extending coaxially completely through the center of the cutting head to conduct cooling/lubricating fluid to cutting inserts mounted at outer ends of the grooves. The grooves induce a flow of fluid from inner ends of the grooves to the outer ends in response to rotation of the cutting head. A removable deflector can be attached to the end surface to deflect fluid from the main duct to the grooves.
