Abstract
A saw blade includes a body and a plurality of cutting teeth formed on the body. The plurality of cutting teeth include a first cutting tooth having a tip adjacent a first end of the first cutting tooth, a rake face defining a rake face line extending from the tip toward the body at a positive rake angle, and a relief face extending from the tip toward a second end of the first cutting tooth. The saw blade also includes a plurality of gullets formed on the body between the plurality of cutting teeth. The plurality of gullets include a first gullet forming an undercut of the first cutting tooth. At least a portion of the undercut is positioned on a side of the rake face line in a direction opposite a cutting direction of the saw blade.
Claims20
A saw blade comprising:
- a body;
- a plurality of cutting teeth formed on the body, the plurality of cutting teeth including a first cutting tooth having a tip adjacent a first end of the first cutting tooth, a rake face defining a rake face line extending from the tip toward the body at a positive rake angle, and a relief face extending from the tip toward a second end of the first cutting tooth, the rake face of the first cutting tooth configured to cut a workpiece when the saw blade moves in a cutting direction;
- and
- a plurality of gullets formed on the body between the plurality of cutting teeth, the plurality of gullets including a first gullet forming an undercut of the first cutting tooth between the body and the rake face, at least a portion of the undercut positioned on a side of the rake face line in a direction opposite the cutting direction.
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, the plurality of tooth bodies including a first tooth body having a rake face defining a rake face line extending from a first end of the first tooth body toward the saw blade body at a positive rake angle, the first tooth body also having a relief face extending from the first end toward a second end of the first tooth body, the first tooth body configured to cut a workpiece when the saw blade moves in a cutting direction;
- and
- forming a plurality of gullets on the saw blade body between the plurality of tooth bodies, the plurality of gullets including a first gullet forming an undercut of the first tooth body between the saw blade body and the rake face, at least a portion of the undercut positioned on a side of the rake face line in a direction opposite the cutting direction.
