Abstract

L'invention conerne un foret à auto-chanfreinage présentant une tige (12) dans laquelle est formée une gorge longitudinale (28). Une pièce rapportée (36) saillante résiliente est placée dans la gorge. Sur la pièce rapportée est formée une extrémité (44) coupante saillante radialement. L'extrémité coupante présente des bords coupants (46, 48) biseautés vers l'avant et vers l'arrière de sorte que, à mesure que le foret avance pour percer un trou dans un pièce à usiner (60), le bord coupant biseauté vers l'avant de l'extrémité coupante chanfreine la face antérieure du trou. Ensuite, l'extrémité coupante se rétracte dans la gorge à mesure qu'elle passe à travers la pièce à usiner, et à mesure que ladite extrémité coupante sort du côté arrière de ladite pièce à usiner, le bord coupant biseauté arrière de l'extrémité coupante chanfreine automatiquement le côté arrière du trou percé dans ladite pièce à usiner.
