ABSTRACT:
A cutter head of a planer machine includes a rotatable mount body having opposite flat mount and counter regions that are symmetrical to each other, a cutter blade disposed to abut against the flat mount region so as to enable a cutting edge to extend beyond a lateral end of the mount region, a press member having a tightened body which is tightened against the mount region, and a pressing strip which is brought to press the cutter blade against the mount region, and a counterweight disposed on the counter region so as to balance the combined weights of the cutter blade and the press member for smoothing the rotation of the mount body.
