Abstract:
A rotatable tool for chip removing machining comprising:a holder part defining a center axis of rotation, the holder part including an axially front end in which a slot is formed between elastically flexible branches of the holder part, the branches being elastically deformable from a rest state thereof, and a cutting part detachably connected to the branches, the holder part and the cutting part together forming a male/female coupling comprising a male part disposed on one of the holder part and the cutting part, and a female part formed in the other of the holder part and the cutting part, the male part received in the female part, each of the male part and the female part being of at last partially circular cross section, the one of the male part and the female part disposed on the holder part having a diameter variable in size in response to manually induced elastic deformation out of their rest state, wherein the elastic deformation causes a smallest diameter of the female part to be larger than a largest diameter of the male part to permit joining of the male part and the female part, and wherein a return of the branches to their rest state causes a minimum diameter of the female part to be smaller than a largest diameter of the male part to prevent removal of the cutting part from the holder part.
