The invention relates to a rotary or fixed cutting tool (1) for machining elements made of a hard and/or abrasive material, said tool comprising at least one active portion having hardness and/or abrasion properties higher than that of the material to be machined, and a passive portion interacting with a tool holder including a clamp (7), characterised in that the active portion (PA) and the passive portion (PP) of said tool are formed by an integral plate defining both portions and obtained directly from a blank having a predetermined constant thickness and a hardness corresponding to that of the active portion (PA) so as to obtain a planar tool, and in that the passive portion (PP) is elongate and has a constant substantially quadrangular cross-section for interaction with a housing (3) with a corresponding cross-section in the clamp (7), wherein the integral planar tool (1) thus formed is directly mounted in the housing (3) secured by tightening the same in the clamp (7).
Outil de coupe (1), tournant ou fixe, destiné à l'usinage d'éléments réalisés en matière dure et/ou abrasive, constitué d'au moins une partie active présentant des propriétés de dureté et/ou d'abrasion supérieures à celles de la matière à usiner, et d'une partie passive destinée à coopérer avec un porte-outil comportant une pince (7), caractérisé en ce que la partie active (PA) et la partie passive (PP) dudit outil sont formées par une plaquette monobloc définissant les deux parties, obtenue directement à partir d'un flan d'épaisseur constante prédéterminée et de dureté correspondant à celle de la partie active (PA), de manière à obtenir un outil plat, et en ce que sa partie passive (PP) est longiligne et de section constante, globalement quadrangulaire, destinée à coopérer avec un logement (3) de section correspondante de la pince (7), dans lequel logement (3) se monte directement l'outil plat monobloc (1) ainsi formé, pour fixation par serrage dans la pince (7).
