A cutting tool has an adjusting mechanism for a cutting insert. The adjusting mechanism includes a wedge element in the form of a conical head on a set screw, as well as a sleeve mountable in the base body of the tool. Two jaws are included in the sleeve, a first one of which is wider than the second and has two rearwardly directed pressure surfaces for cooperation with two secondary support surfaces in the base body. A front surface on the first jaw 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 is activated by tightening the set screw, whereby the second jaw supports itself against the base body, and then the first jaw is set in motion forwards in order to push out the cutting insert axially in fine steps.
