The invention relates to a cutting tool having an adjusting mechanism for a cutting insert (not shown) that is possible to fix in an insert seat (10) in the tool. The adjusting mechanism includes a wedge element in the form of a conical head (17) on a set screw (15), as well as a sleeve (14) mountable in the basic body (2) of the tool. Two jaws (29, 30) are included in the sleeve, a first one (29) of which is wider than the second (30) and has two rearwardly directed pressure surfaces (32) for co-operation with two secondary support surfaces (40) in the basic body (2). A front surface (31) on the first jaw (29) is always kept pressed against a rear surface on the cutting insert, whereby the cutting insert is kept in a basic position. When the cutting insert is to be finely-adjusted, the second jaw (30) is activated by tightening the set screw (15), whereby the second jaw supports itself against the basic body, and then the first jaw (29) is set in motion forwards in order to push out the cutting insert axially in fine steps, e.g. 1/1000 mm. <IMAGE> |
