FIELD: technological processes.
SUBSTANCE: tool (100) has a plurality of cutting portions (108) arranged along the peripheral surface (106) alternately between its side surfaces (104) with a cutting insert (112) retained in each cutting portion (108). At least one cutting portion (108) has a main recess (114) formed on a side surface (104) opposite to the side surface, in which the corresponding cutting insert (112) is located. The main recess (114) has an arcuate surface (116) and a supporting surface (118). The cutting portion (108) also has a cam element (124) with an arcuate surface (126) and a supporting surface (128), located on opposite sides of the pivot axis (P). The cam element (124) is located within the main recess (114), the arcuate surface (126) being adjacent to the arcuate recess surface (116), and the cam support surface (128) being adjacent to the recess support surface (118). The cutting portion (108) is made movable along the axis of the cutting tool between the neutral position and the adjusted position, when the cam element (124) rotates about the axis (P).
EFFECT: regulating the passage width of the cutting tool.
