The present invention relates to a milling disc formed generally in a shape of a disc having a center axis (4). The milling disc comprises: an outer circumference (9) including a plurality of cutting blades (12); a first side (5) having a bearing surface (6) around the center axis; and an attaching unit (15) interlocking with a mating attaching unit of a rotatable mounting shaft to permit rotation preventing attachment of the milling disc in the rotatable shaft, and pressing the bearing surface towards the mounting surface on an end surface of a shaft. The milling disc also includes at least a flushing fluid channel (22) having a limited cross section, and extended from an inlet (21) of the bearing surface (6) to at least an outlet (20) on the circumference (9) in the milling disc. The present invention also relates to the rotatable mounting shaft to attach the milling disc to be able to rotate. |
