A cutting tool comprises a housing, in the openings of which the cylindrical cutting inserts with central holes are installed, which are fixed with screws mounted in various holes in the housing perpendicular to the axes of the holes for cutting inserts, on lateral surfaces of the cutting inserts one or two parallel flats are made and the diameter of the central hole of cutting inserts is determined by a ratio. A screw located closer to the cutting part of the insert, where the section of central hole is blind, is selected from a standard range of diameters of threaded screws with a thread diameter of at least for one position larger as compared with the diameter of screw thread located from the other side of the cutting insert, where the section of the central hole is through.
