FIELD: technological processes.
SUBSTANCE: tool (10) comprises cutting head (12), which contains bushing (16) and cutting element (18) attached to bushing (16), and holder (14), made with possibility of attachment of cutting head (12) with possibility of disconnection. In assembled state of tool (10) cutting head (12) and holder (14) are screwed together by means of internal thread (40), which is located in bushing (16), and external thread (42), which corresponds to internal and is located on holder (14). In the assembled state of tool (10), cutting head (12) and holder (14) contact each other along the first axial bearing surface (36), which is located on bushing (16), and the second axial bearing surface (38), which corresponds to the first and is located on holder (14), as well as along the first conical bearing surface (44), which is located on bushing (16), and the second conical bearing surface (46), which corresponds to the first one and is located on holder (14).
EFFECT: higher accuracy of cutting head positioning.
