ABSTRACT:
A file/rasp tool has upstanding teeth with curved cutting edges, arranged in a plurality of rows. The rasp teeth are of generally pyramidal shape and have a cutting face with a positive rake or slope, such cutting face being defined by upwardly converging side edges surmounted by a cutting tip or edge of generally arcuate configuration having a radius of curvature at least equal to the depth of the teeth. The file teeth have cutting edges including a cap portion at the tip of the tooth and extending therefrom at a forward angle to the front face of the tooth. Such tooth configurations provide a tool which has an extended useful life.
