  • Publication number: 20020090273
    Abstract: The rotary cutting tool of the present invention employs roughing and finishing blades on the same tool to produce roughing and finishing cuts in one cutting operation. The rotary cutting tool preferably has a roughing flute adjacent to each roughing blade and a finishing flute adjacent to each finishing blade. In highly preferred embodiments, the finishing flutes are smaller than the roughing flutes. Preferably, each finishing flute is located closer to the preceding roughing flute (with reference to tool rotational direction) than to the following roughing flute. The flutes are therefore preferably unequally spaced. In some highly preferred embodiments, the blades are unequally circumferentially spaced and are immediately behind the flutes. At least one finishing blade preferably extends radially farther than at least one roughing blade. Most preferably, all of the finishing blades extend radially farther than all of the roughing blades.
