FIELD: mechanics.
SUBSTANCE: accessory is arranged in the form of cutting tool, comprising body arranged along longitudinal axis equipped with mechanism of fine tuning of radial position of cutting plates, besides seat for plates has surface of adjacency, in direction to which cutting plate is tightened openly on the cutting side, and opposite to it has back support wall arranged in the form of spacer spline of elastic link, which is connected to remaining body. Adjusting screw is arranged with the possibility of screwing into spacer spline for fine tuning of radial position of cutting plate.
EFFECT: for increase of adjustment accuracy and reduction of dimensions, spacer spline has longitudinal arm and transverse arm, which is arranged perpendicularly to longitudinal arm and parallel to surface of adjacency, and which connects longitudinal arm with seat for plates.
