ABSTRACT:
The reamer having an interchangeable cutter head and a coolant-lubricant feed (24, 25, 26, 27) supplying the cutter head from outside includes a coaxial opening (2) for receiving the cutter head, which is cylindrical. The end of the coaxial opening nearest the reamer shank (1) is provided with an outwardly opening first cone (13), the conical surface of which is provided with deepened portions (14) at three locations. The cutter-head shank (4) is cylindrical and insertable in the coaxial opening of the reamer shank until a thickening forming a second cone (12) rests against the first cone of the reamer shank. By means of a clamping bolt (8) passing through the cutter head, the second cone can be pressed into the first cone, which becomes deformed. This deformation also affects the wall of the reamer shank in the front region of the coaxial opening, whereby the cutter-head shank is likewise held. The clamping bolt can additionally be used for expanding the cutter head.
