Abstract

L'invention concerne un foret-bêche. L'extrémité fendue de serrage de la lame du porte-lame 2 comporte des surfaces d'extrémité 16 biseautées en sens inverse, chacune perpendiculaire à la face latérale respective de la lame 6 et inclinée à angle A inférieur à l'angle B de l'arête tranchante 17 coopérante, pour former des passages convergents formant, en section transversale, un angle droit qui servent à guider les copeaux jusqu'à des rainures longitudinales 12 diamétralement opposées du porte-lame 2 qui forment, en section transversale, un angle obtus. Application à la fabrication des forets-bêches.
