ABSTRACT:
A tooth for a circular saw or a mower drum that can be used to cut standing trees or brush and undergrowth. The tooth has four cutting edges arranged in a first pair of opposed cutting edges that are generally straight and a second pair of opposed cutting edges that are generally concave. The tooth is mounted in a holder in a first or second cutting position that orients a cutting edge of the first or second pair to physically contact and effect a cutting method to a cuttable material. In a first cutting method, a generally straight cutting edge contacts the material, resulting in a slicing action. In a second cutting method, a generally concave cutting edge contacts the material, resulting in a gouging action. Teeth in the circular saw or brush mower alternate between first and second cutting positions, allowing both cutting methods to be applied to cuttable material.
