Abstract (en)

[origin: DE19855364A1] The invention relates to a cutting tool for parting and/or formatting sheet material such as plastic sheets and similar, comprising a rotationally driven support body (1) on whose periphery a number of cutting teeth (2) are located. Said cutting teeth (2) have a radially outlying front-cutting area (3) with parting blades (5) and are provided with main blades (7, 7') in a formatting area (4), these main blades determining the cutting width of the tool (9). According to the invention, the main blades (7, 7') are arranged in such a way that they are radially separated from the parting blades (5, 5') on the cutting tooth (2) by a transitional area (6), so that the formation of the cuttings on the parting blades (5, 5') is interrupted. This enables the parting and formatting processes to be carried out with tear-free cut edges and smooth cut surfaces and ensures that the cutting tool requires as little energy as possible.
