Saw blade

A reciprocating saw blade for use with a reciprocating saw, the reciprocating saw blade comprising:

• a body defining a longitudinal axis;
• an attachment portion coupled to the body, the attachment portion 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 relief surface, and a protrusion, each tip spaced a separation distance from a corresponding protrusion in a direction perpendicular to the longitudinal axis, the relief surface directly interrupted by the protrusion, the tip of a respective cutting tooth being closer than the protrusion of the cutting tooth to the attachment portion along a direction parallel to the longitudinal axis;
• and
• a gullet defined between the tip of a first cutting tooth and the protrusion of an adjacent second cutting tooth, the gullet including a base;
• wherein the tip is spaced a tip height distance from the base of the gullet in a direction perpendicular to the longitudinal axis;
• and
• wherein the separation distance is greater than or equal to 32% of a length of the tip height distance.

A reciprocating saw blade for use with a reciprocating saw, the reciprocating saw blade comprising:

• a body defining a longitudinal axis;
• an attachment portion coupled to the body, the attachment portion 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 and a rounded protrusion, the rounded protrusion of a first cutting tooth spaced a gap distance from the tip of an adjacent second cutting tooth in a direction parallel to the longitudinal axis, the tip of the first cutting tooth being closer than the rounded protrusion of the first cutting tooth to the attachment portion along a direction parallel to the longitudinal axis, and
• a gullet defined between the tip of a first cutting tooth and the protrusion of an adjacent second cutting tooth, the gullet including a base;
• wherein each cutting tooth defines
• an effective relief surface that extends from the tip and is tangent to the rounded protrusion, the effective relief surface of the first cutting tooth spaced apart from an effective relief surface of the adjacent second cutting tooth by an offset distance extending in a direction perpendicular to the first effective relief surface,
• a tip height extending in a direction perpendicular to the longitudinal axis from the base of the gullet to the tip of the cutting tooth, and
• a rake face that extends from the tip toward the longitudinal axis along a majority of the tip height;
• and
• wherein a ratio of the gap distance to the offset distance is greater than 1.1.
