Abstract

A saw blade is stamped with a circumferential edge. At least one deep gullet and shoulder are formed in the circumferential edge. Likewise, a tooth pocket is formed in the circumferential edge. The tooth pocket is defined by a wall, generally radial to circle, on the shoulder, and a shelf substantially perpendicular to the wall. A tooth is secured, ordinarily by brazing, in the pocket such that the thickness of the tooth is substantially equal to the depth of the shelf and the face of the tooth is continuous with the gullet. The tooth may be brazed along its entire lateral edge such that resultant forces in the tooth are transmitted to the body of the blade. After the tooth is positioned into the tooth pocket, the tooth, as well as a projection of the blade shoulder, are ground off so that the tooth and shoulder are flush with one another. Thus, the tooth longitudinal edge is in complete contact with the shoulder wall maximizing its strength.

Dependent claims

A saw blade comprising:

a body having a circumferential edge;
at least one gullet formed in said circumferential edge;
at least one shoulder formed in said circumferential edge adjacent said gullet;
a tooth pocket formed in said circumferential edge, said tooth pocket defining a wall and a shelf adjacent to said wall, said shelf having a desired depth;
a tooth secured in said pocket such that said tooth having a thickness substantially equal to the depth of said shelf so that a face of the tooth is continuous with the gullet, and said shelf enables a lateral edge of the tooth to be secured with the body, said gullet includes a first side angled with respect to the circumferential edge toward the tooth, a bottom, said bottom being on a straight tangent line to an arc which is concentric with the circumferential edge and a second side, terminating at said shelf and angled with respect to the circumferential edge away from the tooth, said first and second sides being directly continuous with said bottom and angled towards one another.
