The cutter plates (14,15) are set on adjoining seats (7,8) of the cutting tool (2), each plate having front (17,27), base (18,28) and side faces (20,32). The seats are arranged so their plates make one side contact when the plates are seated. The bearing surfces (24,26) of adjoining plates are set at spacing in relation to the perpendicular to the bearing surfaces (24,26), the spacing to be less than the thickness of the deeper set plate (15). The side face (32) of plate (15) is divided into two areas, using the area at obtuse angle to the front face to make contact with the adjoining plate. The side face (20) of the plate (14) contacting the plate face (32) forms an obtuse angle with the base surface (18), equal to that between face part (32) and plate face (27). |
