ABSTRACT:
A cup-shaped wheel having an abrasive rim is employed to grind the teeth of a circular saw to an improved contour. Only point or edge contact takes place between the abrasive rim and the tooth. This technique is preferably utilized in conjunction with triple-chip type circular saws of the sort used to cut metals such as steel. The contour imparted to the cutting surface of the tooth comprises a section of an elliptical cylinder and exhibits improved steel cutting characteristics when compared to prior art multi-faceted saw teeth. Since only edge contact takes place between the abrasive rim and the tooth, the wheel is essentially self-dressing.
