ABSTRACT:
The invention relates to a machine tool, particularly a machine reamer, comprising a shaft-type base and a replaceable cutter head which frontally protrudes from the base. An axially protruding extension of said cutter head engages into a frontal receptacle that is fixed to the base, the cutter head being removably clamped in said receptacle by means of a clamping screw which penetrates the replaceable cutter head in a truly axial direction. The screw head of the clamping screw rests against a face of the replaceable cutter head. The extension of the replaceable cutter head is provided with a polygonal part which is complementary to a truly axial polygonal hole that is fixed to the base and is penetrated by the polygonal part. The extension is further provided with an externally conical part which adjoins the polygonal part, engages into a conical hole that is fixed to the base, and is complementary to said conical hole while the clamping screw is screwed into a central internal thread that is fixed to the base. Preferably, the base is equipped with a functional insert which is rigidly connected to the base and contains the internal thread, the polygonal hole, and/or the conical hole.
