Rotatable tool with removable cutting part

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,
• 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 disposed on the other of the holder part and the cutting part, the male part received in the female part,
• first support surfaces formed on the front end of the holder part, and second support surfaces formed on the cutting part and engaging the first support surfaces, the first and second support surfaces situated radially outside of the male/female coupling and being at least partially conically shaped for elastically urging the male and female parts radially together in response to the transmittal of axial thrust loads from the second support surfaces to the first support surfaces.
