  • Patent number: 7320565
    Abstract: In a first aspect, the invention relates to an edge-carrying drill body (1) of the type that is intended for deep hole drilling, and which is rotatable around a geometric axis (C) as well as comprises a through channel (2) arranged for internal chip evacuation, which channel mouths in front and rear ends of the body. Characteristic of the invention is that one or more cutting edges (4) are made integrally with the rest of the body, more precisely from a hard material, such as cemented carbide or CERMET. In a second aspect, the invention also relates to a method for the manufacture of such a drill body. In a third aspect, the invention furthermore relates to a drilling tool for deep hole drilling.

  • Publication number: 20040265080
    Abstract: A deep hole drill is rotatable around a geometric axis and includes a body defining a through-channel arranged for internal chip evacuation. The channel opens in front and rear ends of the body. One or more cutting edges are made integrally with the rest of the body, more precisely from a hard material, such as cemented carbide or CERMET. A front bridge of the body extends across the front channel and possesses the integral cutting edge(s).

  • Patent number: 6695551
    Abstract: A rotatable cutting tool includes a rotatable tool body and a replaceable cutting tip for chip removing machining. The tool body includes a forward free end having a first dovetail coupling part formed thereon. The cutting tip includes a front cutting end and a rear mounting end. The mounting end includes a second dovetail coupling part joined to the first dovetail coupling part. An actuator, such as a screw, is provided which is arranged for elastically deforming one of the dovetail coupling parts to create a tightly clamped relationship between the first and second dovetail coupling parts. Insertion of a replacement cutting tip is performed by laterally mating the dovetail coupling parts until one of the coupling parts abuts a laterally facing stop surface of the other coupling part.
