    Abstract: A replaceable cutting piece and a cutting arm for a debarking cutter for a debarking machine of a hollow-rotor type, which cutting piece (6) and cutting arm (4) comprise supporting surfaces and abutment surfaces for receiving loads acting on the cutting piece fastened by a retaining screw to a housing (7) formed in the cutting arm. In order to direct the loads acting on the cutting piece in full to the cutting arm instead of to the retaining screw, the cutting piece and the cutting arm comprise supporting surfaces and abutment surfaces (9a to 9d, 11a, 11b, 12a, 14a, 14b) for receiving the loads acting on the cutting piece in the direction of the axle, the radius and the tangent of the rotor and the torque caused by said loads, which surfaces are situated in perpendicular planes with respect to one another.
