Saw blade
First Claim
1. A reciprocating saw blade for use with a reciprocating saw, the reciprocating saw blade comprising:
- a body having a first end portion and a second end portion, the body defining a longitudinal axis;
an attachment portion coupled to the first end portion of the body, the attachment portion including a tang and an aperture configured to couple to the reciprocating saw;
a cutting portion formed on the body, the cutting portion including a plurality of cutting teeth, each cutting tooth including a tip, a rake face extending from the tip generally toward the longitudinal axis and defining a gullet, and a relief surface extending from the tip generally toward the second end portion of the body; and
a plunge point formed on the second end portion of the body for initiating a plunge cut, the plunge point including a leading tooth having a tip, a rake face extending from the tip generally toward the longitudinal axis and defining a leading gullet, and a relief surface extending from the tip to an end of the body;
wherein the tips of the plurality of cutting teeth and the tip of the leading tooth define a plane that is generally parallel to the longitudinal axis, wherein a first angle between the plane and the rake face of the leading tooth, measured through the leading tooth, is greater than 90 degrees, and wherein a second angle between the plane and the rake face of each cutting tooth, measured through the corresponding cutting tooth, is less than 90 degrees;
wherein a third angle between the plane and the relief surface of the leading tooth is at least twice as large as a fourth angle between the plane and the relief surface of each cutting tooth.

Abstract
A reciprocating saw blade includes a body defining a longitudinal axis, an attachment configured to couple to a reciprocating saw, and a cutting portion. The cutting portion includes a plurality of cutting teeth, each having a tip and a rake face. The saw blade also includes a plunge point for initiating a plunge cut. The plunge point includes a leading tooth having a tip and a rake face extending from the tip. The tips of the plurality of cutting teeth and the tip of the leading tooth define a plane that is generally parallel to the longitudinal axis. A first angle between the plane and the rake face of the leading tooth, measured through the leading tooth, is greater than 90 degrees. A second angle between the plane and the rake face of each cutting tooth, measured through the corresponding cutting tooth, is less than 90 degrees.
