  • Publication number: 20130022416
    Abstract: A shank cutter has plural circumferential cutting edges which run in a helical manner in the region of its cutting section and of which at least one critical number are equipped in each case with a preferably essentially flattened roughing profile with chip-separating grooves with rounded bases, so that the chip-separating grooves of cutter ridges which are adjacent in the circumferential direction are axially offset relative to each other. To create a tool which provides long service life by combined advantages of a vibration-stabilized finishing cutter and a conventional roughing cutter, at least one circumferential cutting edge has an angle of twist which differs from that of another circumferential cutting edge. In addition, the chip-separating grooves of the circumferential cutting edges which are equipped with a roughing profile in each case merge into a preferably essentially flattened central section of the roughing profile by means of a predefined flank radius.
