Abstract
A saw blade includes a body and a plurality of cutting teeth formed on the body. Each cutting tooth includes a tip at a first end of the cutting tooth, a rake face extending from the tip toward the body, a relief face extending from the tip toward a second end of the cutting tooth and sloping toward the body, and a projection at the second end of the cutting tooth and sloping away from the body. The saw blade also includes a plurality of gullets formed on the body between the plurality of cutting teeth. Each gullet forms an undercut portion between the body and the projection of each cutting tooth.
Claims22
A saw blade comprising:
- a body;
- a plurality of cutting teeth formed on the body, each cutting tooth including a tip at a first end of the cutting tooth, a rake face extending from the tip toward the body, a relief face extending from the tip toward a second end of the cutting tooth and sloping toward the body, and a projection at the second end of the cutting tooth and sloping away from the body;
- and
- a plurality of gullets formed on the body between the plurality of cutting teeth, each gullet forming an undercut portion between the body and the projection of each cutting tooth.
A method of manufacturing a saw blade, the method comprising:
- providing a saw blade body;
- forming a plurality of tooth bodies in the saw blade body, each tooth body including a rake face extending from a first end of the tooth body toward the saw blade body, a relief face extending from the first end of the tooth body toward a second end of the tooth body and sloping toward the saw blade body, and a projection at the second end of the tooth body and sloping away from the saw blade body;
- and
- forming a plurality of gullets in the saw blade body between the plurality of tooth bodies, each gullet forming an undercut portion between the saw blade body and the projection of each tooth body.
A saw blade comprising:
- a body;
- a plurality of cutting teeth formed on the body, each cutting tooth including a first tip at a first end of the cutting tooth, a first rake face extending from the first tip toward the body, a second tip at a second end of the cutting tooth, and a second rake face extending from the second tip toward the body, the first rake face having a first linear segment extending from the first tip and a first curved segment between the first linear segment and the body, the second rake face having a second linear segment extending from the second tip and a second curved segment between the second linear segment and the body;
- and
- a plurality of gullets formed on the body between the plurality of cutting teeth, each gullet forming a first undercut portion at the first curved segment of one of the plurality of cutting teeth and a second undercut portion at the second curved segment of an adjacent cutting tooth.
A method of manufacturing a saw blade, the method comprising:
- providing a saw blade body having an edge;
- coupling a carbide strip to the edge of the saw blade body;
- forming a plurality of cutting teeth in the carbide strip and the saw blade body after the carbide strip is coupled to the edge, each cutting tooth including a first tip at a first end of the cutting tooth, a first rake face extending from the first tip toward the saw blade body, a second tip at a second end of the cutting tooth, and a second rake face extending from the second tip toward the saw blade body, the first rake face having a first linear segment extending from the first tip and a first curved segment between the first linear segment and the saw blade body, the second rake face having a second linear segment extending from the second tip and a second curved segment between the second linear segment and the saw blade body;
- and
- forming a plurality of gullets in the saw blade body between the plurality of cutting teeth, each gullet forming a first undercut portion at the first curved segment of one of the plurality of cutting teeth and a second undercut portion at the second curved segment of an adjacent cutting tooth.
