A tool for use in machine-tools with a cutting head (14) has at least one interchangeable cartridge (24) which can be releasably fastened to the cutting head and which carries an interchangeable insert. The interchangeable cartridge can be adjusted on the cutting head in the advance direction of the insert by the action of an adjustment mechanism. The adjustment mechanism has a tapered ram (46) which can move along a guide (42) of the cutting head (14) arranged parallel to the plane of the insert and essentially perpendicular to the advance direction of the cutting head (14). The tapered ram has a tapered surface (44) which is inclined at an acute angle to the direction of sliding and which is contiguous with an inclined shoulder (54) of the interchangeable cartridge which makes a right angle, in the direction of the inclined tapered surface, with the advance direction. In order to transfer the torsional stresses produced by the cutting force on the blade of the tool to the cutting head (14) without stressing the means for securing the interchangeable cartridge (24 ), the inclined shoulder (54) and the facing tapered surface (44) also have an inclined undercut perpendicular to the inclined tapered surface and transverse to the advance direction, which enables the interchangeable cartridge (24) to interlock with the conical ram (46).
In a tool for use in machine tools with a rotatably supported cutting head and at least one interchangeable cartridge releasably fastenable on the cutting head and carrying a planar interchangeable insert, which interchangeable cartridge is, with the aid of an adjustment mechanism, adjustable on the cutting head in a direction parallel to an axis of rotation of the cutting head, the improvement wherein the adjustment mechanism includes a tapered ram movable along a guide means on the cutting head, which guide means is aligned parallel with respect to a plane containing the planar interchangeable insert and substantially transversely with respect to the axis of rotation, wherein the tapered ram has an inclined tapered surface, which defining an acute angle with a longitudinal direction of movement thereof in said guide means, said inclined tapered surface resting flat against an inclined shoulder on the interchangeable cartridge, which inclined shoulder deviates, in direction of the inclined tapered surface, from a right angle with respect to the axis of rotation, and wherein the inclined shoulder and the opposing tapered surface, transversely with respect to the inclined tapered surface, define an interlock means between the interchangeable cartridge and the tapered ram for absorbing forces applied to said interchangeable insert.
