Cutter Mounting Systems and Cutters for the Same

A cutter configured to be mounted on a rotationally driven apparatus for material reduction of an object, the cutter comprising:

• a first end including a cutting tip configured to first engage the object along a dominant force vector;
• a second end opposite the first end;
• a first side;
• and
• a second side opposite the first side;
• the cutter having a length between the first end and the second end, and a width between the first side and the second side;
• the cutter further including
• an outer surface;
• and
• an inner surface having portions configured to engage the rotationally driven apparatus, the inner surface including
• a mounting surface portion configured to engage a first surface of the apparatus;
• and
• a plurality of reaction surface portions configured to engage mating surfaces of the apparatus and disposed between the mounting surface portion and the first end, at least two of the plurality of reaction surface portions being angled relative to one another such that the plurality of reaction surface portions extend along the width from the first side to the second side in a non-planar manner;
• and
• an aperture extending from the outer surface to the mounting surface portion along a fastener axis that is substantially perpendicular to the mounting surface portion and to the dominant force vector, the aperture configured to receive a fastener to secure the cutter to the apparatus.

A rotating cutting assembly comprising:

• a wheel configured to be mounted on a rotationally driven apparatus for material reduction of an object;
• a cutter removably coupled to a side surface of the wheel, the cutter including
• a first end configured to first engage the object along a dominant force vector;
• a second end opposite the first end;
• a first side;
• and
• a second side opposite the first side;
• the cutter having a length between the first end and the second end, and a width between the first side and the second side;
• the cutter further including
• an outer side;
• an inner side configured to engage the wheel;
• an aperture extending from the outer side to the inner side along a fastener axis that is substantially perpendicular to the dominant force vector, the aperture configured to receive a fastener to secure the cutter to the wheel;
• and
• a cutter tip on the first end and having a first cutting edge extending along the first side, a second cutting edge extending along the second side, and a third cutting edge extending along the outer side, the cutting edges defining therebetween a cutting face of the cutter tip, the cutting face configured to define a cutting swath having a width between the first cutting edge and the second cutting edge as the cutter rotates with the apparatus;
• wherein no portion of the first side or the second side extends outside the width of the cutting swath;
• and
• wherein the wheel further includes a gullet formed therein and adjacent the cutter, and wherein the gullet includes a straight segment defining a first leg of the gullet positioned adjacent the cutter tip, and an arcuate segment defining a second leg of the gullet.
