The invention relates to a method for producing a cutting tool with a tip (16), a shaft (10) and a chucking groove area in which chucking chambers (12, 14) are provided. Said cutting tool is coated with a hardening component substantially across its entire surface. The invention is further characterized in that before the cutting tool is coated with the hardening component only the tip (16) is micro-blasted. The inventive cutting tool is especially a full carbide drill.

L'invention concerne un procédé permettant de produire un outil d'enlèvement de copeaux qui présente une pointe (16), une tige (10) et une zone à rainure à copeaux dans laquelle sont formées des chambres à copeaux (12, 14), l'outil d'enlèvement de copeaux étant sensiblement complètement recouvert d'une matière dure. Ce procédé se caractérise en ce que, avant le recouvrement de l'outil d'enlèvement de copeaux avec la matière dure, seule la pointe (16) est soumise à une projection de microparticules. L'outil d'enlèvement de copeaux peut en particulier être un foret à carbure métallique massif.
