En reference aux figures 1 et 2, on a represente un corps 1 faisant partie d'un outil selon ['invention et portent une lame de coupe 2 presentant une arete tranchante 3. ' En reference a la figure 3, la lame de coupe 2 est montee a une extremite d'une tige 4 montee coulissante dans une bague 5 fixee dans un alesage traversant 6 du corps 1. La lame de coupe 2 est montee sur une tete 7 epaulee de ia tige 4 par Referring to Figures 1 and 2, there is shown a body 1 forming part of a tool according to ['invention and carry a cutting blade 2 having a cutting edge 3.' With reference to Figure 3, the cutting blade 2 is mounted at one end of a rod 4 slidably mounted in a ring 5 fixed in a through bore 6 of the body 1. The cutting blade 2 is mounted on a head 7 shoulder of the rod 4 by
