FIELD: instrument engineering.
SUBSTANCE: cutting tool (20) includes first and second components (22, 24) having a shape for differential connection with each other. First and second components (22, 24) include peripheral and central coupling threads (32, 34; 36, 38), each of which continues in the screw direction around axis (A, B) of corresponding component (22, 24). Peripheral and central coupling threads (32, 34, 36, 38) of each component (22, 24) are axially displaced relative to each other. First and second components (22, 24) comprise radial stop surface (40, 42), located at the respective peripheral coupling thread (32, 36). In the assembled position of cutting tool (20), radial stop surfaces (40, 42) abut against each other, and peripheral and central coupling threads (32, 34) of first component (22) cooperate along the thread with peripheral and central coupling threads (36, 38) of second component (24) respectively, with the formation of a differential instrumental connection between first and second components (22, 24).
EFFECT: increase in reliability and accuracy of the connection is achieved.
