  • Patent number: 9168599
    Abstract: A cutting disk for a rotary cutting machine includes a disk body having a central axis of rotation and a circumferentially extending outer periphery. A plurality of circumferentially spaced apart cutting teeth is mounted to the outer periphery of the disk body. A chip pocket is defined in the circumferential outer periphery of the disk body between each of the circumferentially spaced apart cutting teeth. Each chip pocket is formed by a chip clearance surface extending radially inwardly into the disk body to form the chip pocket between circumferentially adjacent cutting teeth. The chip pocket is adapted to receive a tooth-produced chip therein, thereby providing more room for chip discharge and thus reducing disk wear.

  • Patent number: 7913432
    Abstract: A cutting tooth assembly for a rotary cutting machine is described. The assembly includes a tooth holder adapted for mounting about the periphery of a rotating element of the rotary cutting machine, and a reversible cutting tooth, removably mounted to said tooth holder. The cutting tooth has opposed first and second cutting faces which are spaced apart along a central tooth axis extending therebetween. Each of the first and second cutting faces at least partially defines more than two cutting edges, and the cutting tooth is reversible by 180 degrees about a transverse tooth axis to dispose a selected one of the first and second cutting faces in an operable cutting position when mounted to the tooth holder.

  • Patent number: 7713006
    Abstract: A replaceable saw tooth for a rotary cutting machine. The saw tooth comprises more than two cutting edges on each of two opposed faces thereof. More specifically, the saw tooth may comprise a body having two cutting faces disposed opposite each other and spaced apart by at least four side faces which are each parallel to an opposite one of the side faces. The side faces are parallel to a central axis extending between the two cutting faces. Four cutting edges are defined between the side faces and each of the two cutting faces.
