The plate has a tooth (30) with a bottom part (30B) behind a part of a top part (30A) that supports directly a cutting plate (31A) and that is limited by a flank zone (33), which spreads on a limited thickness. The bottom part which is left from the top part presents a profile (36) at an average clearing angle (E, F) different from a total clearance angle (D) of the flank zone. |
