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 and a second tooth, the leading tooth including a tip and a rake face extending from the tip generally toward the longitudinal axis and defining a leading gullet that extends from the rake face of the leading tooth to the plurality of cutting teeth, the second tooth being positioned in the leading gullet closer to the leading tooth than to a nearest cutting tooth of the plurality of cutting teeth, and the second tooth being generally smaller than the leading tooth and each of the plurality of cutting teeth;
wherein the plurality of cutting teeth is arranged in a series from the first end portion of the body to the leading gullet without any intervening teeth therebetween; and
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, and wherein a tip of the second tooth is spaced apart from the plane.

Abstract
A reciprocating saw blade for use with a reciprocating saw includes a body defining a longitudinal axis, an attachment portion configured to couple to the reciprocating saw, and a cutting portion formed on the body. The cutting portion includes a plurality of cutting teeth. Each cutting tooth includes 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. The blade also includes a plunge point formed on the body for initiating a plunge cut. The plunge point includes a leading tooth and a second tooth. The leading tooth includes a tip and a rake face extending from the tip generally toward the longitudinal axis and defining a leading gullet. The second tooth is positioned in the leading gullet adjacent the leading tooth and is generally smaller than the leading tooth and each cutting tooth.

14. 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 and a second tooth, the leading tooth including a tip and a rake face extending from the tip generally toward the longitudinal axis and defining a leading gullet that extends from the rake face of the leading tooth to the plurality of cutting teeth, the leading gullet being at least twice as large as each gullet of the plurality of cutting teeth, the second tooth being positioned in the leading gullet closer to the leading tooth than to a nearest cutting tooth of the plurality of cutting teeth, and the second tooth being generally smaller than the leading tooth and each of the plurality of cutting teeth; 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 the plurality of cutting teeth is arranged in a series from the first end portion of the body to the leading gullet without any intervening teeth therebetween; and wherein a tip of the second tooth is spaced apart from the plane. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
