ABSTRACT:
A saw, especially for sawing wood, in which a support disc is provided with peripheral recesses with cutting teeth formed on the forwardly facing rearward sides of the recesses and which teeth may be in the form of hard wear resistant inserts. The cutting teeth are so designed that the kerf taken by the saw as it advances into the saw cut is spaced on both sides from the saw blade and also from the sides of the aforementioned cutting teeth radially inwardly from the tip ends thereof. The teeth are formed to present a positive cutting rake in all directions to the wood and shear the wood fibers off cleanly at the radially outer tip ends of the cutting teeth.
