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.
Claims18
A saw blade comprising:
- a body including a longitudinal axis;
- an attachment portion coupled to the body, the attachment portion including a tang and an aperture configured to couple to a reciprocating saw;
- 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 defining a line extending from the tip toward the body, at a positive rake angle relative to the longitudinal axis of 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 of the plurality of gullets partially defined by a forward curved edge of a corresponding cutting tooth of the plurality of cutting teeth and a rear curved edge of an adjacent cutting tooth of the plurality of cutting teeth, the rear curved edge defining an undercut portion between the body and the projection of the adjacent cutting tooth, the undercut portion positioned on one side of the line defined by the rake face of the corresponding cutting tooth and a portion of the forward curved edge positioned on another side of the line defined by the rake face of the corresponding cutting tooth.

A method of manufacturing a saw blade, the method comprising:
- providing a saw blade body including a longitudinal axis;
- forming an attachment portion in the saw blade body, the attachment portion including a tang and an aperture configured to couple to a reciprocating saw;
- forming a plurality of tooth bodies in the saw blade body, each tooth body including a rake face defining a line extending from a first end of the tooth body toward the saw blade body at a positive rake angle relative to the longitudinal axis of 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 of the plurality of gullets partially defined by a forward curved edge of a corresponding tooth body of the plurality of tooth bodies and a rear curved edge of an adjacent tooth body of the plurality of tooth bodies, the rear curved edge defining an undercut portion between the saw blade body and the projection of the adjacent tooth body, the undercut portion positioned on one side of the line defined by the rake face of the corresponding tooth body and a portion of the forward curved edge positioned on another side of the line defined by the rake face of the corresponding cutting tooth.

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;
- wherein each gullet is partially defined by a forward curved edge of one cutting tooth and a rear curved edge of an adjacent cutting tooth, wherein each rear curved edge defines one undercut portion, wherein each forward curved edge includes a radius measured from a point, wherein a portion of each forward curved edge is located between the corresponding point and the corresponding rake face in a direction transverse to a longitudinal axis of the body.
