Abstract

The invention is directed to a cutterhead for a portable power planer. The cutterhead includes a cylindrical body having a substantially cylindrical surface and defining a rotational axis about which the cylindrical body rotates during normal operation of the power planer. A solid elongated cutting member is provided and has a channel formed therein to define at least two cutting edges. The cylindrical body has an elongated recess formed therein for holding the cutting member. The recess extends in a direction parallel to the rotational axis of the cutterhead and defines a longitudinal aperture in the surface for accommodating one of the cutting edges. The recess has a recess wall extending inwardly away from the aperture to surround and hold the cutting member against the centrifugal forces acting thereupon during the rotation of the cylindrical body. Positioning pins arranged in the cylindrical body engage the cutting bar to angularly fix the cutting member so that the one cutting edge penetrates the aperture at a predetermined angle of elevation with respect to the surface of the cylindrical body. A screw mounted in the cylindrical body directly engages the cutting member to tightly seat the latter against the recess wall.
