  • Patent number: 4610285
    Abstract: The present invention relates to a cutting tool with removable blades and which comprises a stack of discs (2) each having a cut (6) opened on its periphery, and a clamping device compressing the discs, the angular position of the discs relative to each other being such that, in service position, the cuts form peripheral longitudinal housings. Reversible blades (10), the cutting edge (11) of which is situated on a diameter longer than the external diameter of the discs, are fixed in a removable manner in the housings, each by a locking wedge (14) located in the housing parallel to the blade and locking the latter by jamming when the tool is driven in rotation.
