Abstract
A saw tooth for a saw including a square saw tooth body to be mounted on a holder and for receiving inserts fastened to inwardly sloping seating surfaces on the cutting end of the tooth body. The inserts are provided with cutting edges. Between seating surfaces, the cutting end of the tooth body defines recesses for receiving intermediate members fastened therein. The intermediate members are provided with cutting edges, and the intermediate members abut the adjoining inserts to form a cutting surface about the periphery of the cutting end of the saw tooth and help protect the saw tooth body from damage including washout.
