In a cutter disc comprising: a plate-like unit (2) having a central part (21) for seating the fixing hub of the disc on its drive axis, a peripheral flange (22) provided with locations (24, 25) to hold cutters (3) having a pivoted mounting under the flange (22) on axes at the level of the locations (24,25), each location (24, 25) is bounded by at least one rib (28A, B; 29A, B) extending over the central part (21) and over the flange (22) of the plate (2). This rib (28A, B; 29A, B) has a direction akin to a radial direction over the central part (21) of the plate and a direction parallel to the axis (X-X) of the cutter (3) over the part of the peripheral flange (22).
