A cutting tool for expanding or opening up the diameter of boreholes includes at least one reversible knife plate with a front surface. The knife plate can be clamped with at least one clamping shoe into a recess provided in a cutter head. The front surface of the knife plate has at least two grooves which extend essentially parallel and preferably symmetrical with respect to the longitudinal axis of the knife plate. The grooves cooperate with projections provided on the contact surface of the clamping shoe facing the front surface of the knife plate and form a positively locked connection therewith.

La plaque tranchante peut être serrée à l'aide d'au moins un patin de serrage dans un évidement se trouvant dans la tête de coupe. La surface frontale de la plaque tranchante comporte au moins deux rainures qui s'étendent de manière essentiellement parallèle et, de préférence, symétriquement par rapport à l'axe longitudinal de la plaque tranchante.
