A cutting tool and process for the formation thereof. The cutting tool comprises a basic body (1) presenting an active end portion (2) coated with a diamond film obtained by the CVD growth technique, having superficial accidents (10) that are arranged and dimensioned to produce a substantial increase of the seating area for the diamond film and an increased degree of mechanical interference with the latter. This invention refers to the cutting tool above and to the process of obtaining said tool, to be generally used for cutting, drilling, abrading and trimming, and particularly to be coupled to ultrasonic systems.
