Saw blade

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 separated from an immediately adjacent one of the plurality of cutting teeth by a gullet, each cutting tooth including a rake face, a relief surface, and a tip defined by a junction of the rake face and the relief surface, wherein the relief surface extends from the tip generally toward the second end portion of the body, wherein a pitch is defined as the distance between the tips of immediately adjacent cutting teeth, and wherein the tips of the plurality of cutting teeth define a plane that is generally parallel to the longitudinal axis;
• and
• a plunge point formed on the second end portion of the body for initiating a plunge cut, the plunge point including a plunge tooth having a rake face, a relief surface, a tip defined by a junction of the rake face and the relief surface, and a leading gullet disposed between the plunge tooth and a nearest tooth of the plurality of cutting teeth, wherein the relief surface extends from the tip generally toward an end of the plunge point, wherein the tip of the plunge tooth is spaced apart from the plane, wherein the leading gullet is longer than the pitch of the plurality of cutting teeth;
• wherein a first angle between the plane and the rake face of the plunge tooth is measured through the plunge tooth, wherein a second angle between the plane and the rake face of the nearest tooth is measured through the nearest tooth, and wherein one of the first angle and the second angle is greater than 90 degrees and the other of the first angle and the second angle is less than 90 degrees;
• wherein at least the nearest tooth of the plurality of cutting teeth is set relative to a hypothetical plane defined by 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 plunge tooth having a rake face, a relief surface, a tip defined by a junction of the rake face and the relief surface, and a leading gullet disposed between the plunge tooth and a first tooth of the plurality of cutting teeth closest to the plunge tooth, wherein the relief surface extends from the tip towards an end of the plunge point, and wherein the tip of the plunge tooth is spaced apart from the plane;
• wherein a first angle between the plane and the rake face of the plunge tooth is measured through the plunge tooth, wherein a second angle between the plane and the rake face of the first cutting tooth is measured through the first cutting tooth, and wherein the first angle is greater than 90 degrees and the second angle is less than 90 degrees;
• wherein at least the first cutting tooth of the plurality of cutting teeth is set relative to a hypothetical plane defined by the body;
• wherein the rake face defining the first angle is spaced from the rake face defining the second angle by a distance greater than the pitch of the plurality of cutting teeth.
