<p>Said tool can be dismantled but this does not make it less sturdy than integral tools. The fact that it can be dismantled makes it possible to exchange the wearing part, i.e. the cutter. Moreover the cuttting part can be mounted in predetermined angle positions so that only one tool is required for various angle positions, whereas previously one tool was required for every desired angle position. Said tool consists of a cutting part (1), a guiding part (2) and a shank part (3, 3'), which can all be separated from each other. The cutting part has a form closure (16, 16') which fits into a recess in the guiding part (2) and by means of which the cutting part (1) can be centred and the cutter (1') can be immobilized in a given angle position ( alpha ) of the cutting part (1).</p> |
