Saw blade
First Claim
1. A reciprocating saw blade for use with a reciprocating saw, the reciprocating saw blade configured to cut a work piece having a nail extending therethrough, the reciprocating saw blade comprising:
- a body defining a longitudinal axis;
an attachment portion coupled to the body, the attachment portion including a tang and an aperture configured to couple to the reciprocating saw; and
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 at least partially defining a gullet, a relief surface extending from the tip and having a first end that is closer to the attachment portion and a second end that is further from the attachment portion, and a protrusion extending from the second end of the relief surface, the protrusion of each cutting tooth inhibiting the nail from entering the gullet and contacting the rake face of an adjacent cutting tooth during cutting operations;
wherein the tips of the plurality of cutting teeth define a first plane that is generally parallel to the longitudinal axis and the protrusions of the plurality of cutting teeth define a second plane that is generally parallel to the longitudinal axis, and wherein a distance between the first plane and the second plane is at most 0.035 inches; and
wherein a distance between the protrusion of one cutting tooth and the tip of an adjacent cutting tooth, measured generally parallel to the longitudinal axis, is 0.08 inches.

Abstract
A reciprocating saw blade includes a body defining a longitudinal axis. The saw blade includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a tip, a rake face at least partially defining a gullet, a relief surface, and a protrusion extending from an end of the relief surface. The protrusion of each cutting tooth inhibits a nail from entering the gullet. The tips of the plurality of cutting teeth define a first plane that is generally parallel to the longitudinal axis and the protrusions of the plurality of cutting teeth define a second plane that is generally parallel to the longitudinal axis. A distance between the first plane and the second plane is at most 0.035 inches, and a distance between the protrusion of one cutting tooth and the tip of an adjacent cutting tooth, measured generally parallel to the longitudinal axis, is 0.08 inches.

16. A reciprocating saw blade for use with a reciprocating saw, the reciprocating saw blade configured to cut a work piece having a nail extending therethrough, the reciprocating saw blade comprising:
-
a body defining a longitudinal axis; an attachment portion coupled to the body, the attachment portion including a tang and an aperture configured to couple to the reciprocating saw; and a cutting portion formed on the body, the cutting portion including a plurality of cutting teeth and a plurality of gullets positioned between the plurality of cutting teeth, each cutting tooth including a tip, a rake face extending from the tip generally toward the longitudinal axis and at least partially defining one of the plurality of gullets, a relief surface extending from the tip and having a first end that is closer to the attachment portion and a second end that is further from the attachment portion, and a protrusion extending from the second end of the relief surface, the protrusion of each cutting tooth inhibiting the nail from entering the gullet and contacting the rake face of an adjacent cutting tooth during cutting operations. - View Dependent Claims (17, 18, 19, 20)
