Abstract
A reciprocating saw blade includes a body with a shank end configured to secure the blade with a reciprocating saw, a plunging end configured to enter a workpiece, and a cutting edge and opposite back edge extending between the shank end and the plunging end. The cutting edge is formed to include a plurality of teeth arranged in a repeating pattern that includes left set teeth and right set teeth, the plurality of additional teeth being substantially the same size as each other and as the third tooth, wherein the plurality of additional gullets are substantially the same size as each other, and wherein the enlarged first gullet is longer in an axial direction than each of the plurality of additional gullets.
Claims20
A reciprocating saw blade comprising:
- a body extending generally along an axis and having a rear end portion and a front end portion;
- a shank coupled to the rear end portion and configured to be received in a blade holder of a powered saw;
- a non-cutting back edge extending between the rear end portion and the front end portion;
- and
- a cutting edge extending between the rear end portion and the front end portion opposite the back edge, the cutting edge including a plurality of teeth that include an unset front tooth immediately adjacent the front end portion and a plurality of additional teeth following the front tooth toward the rear end portion, the front tooth and the plurality of additional teeth each having cutting tips substantially aligned along a line parallel to the axis,
- wherein the plurality of additional teeth includes an unset leading tooth closest to the front tooth and a plurality of left set teeth and right set teeth following the leading tooth toward the rear end portion, the plurality of additional teeth each being substantially the same size as each other with each additional tooth spaced from an adjacent additional tooth by a first distance, and
- wherein the front tooth is spaced from the leading tooth by a second distance that is greater than the first distance, the second distance being at least 1.5 times as long as the first distance.

A reciprocating saw blade comprising:
- a body extending along an axis and including a shank end configured to couple the reciprocating saw blade with a reciprocating saw, a nose end opposite the shank end, a cutting edge extending between the shank end and the nose end, and a back edge opposite the cutting edge and extending between the shank end and the nose end,
- wherein the cutting edge includes a plurality of set teeth arranged in a pattern that includes left set teeth, right set teeth, and a plurality of gullets, each of the plurality of set teeth and the plurality of gullets having substantially the same size,
- wherein the cutting edge additionally includes a first tooth immediately adjacent the nose end that is flattened to be unset and has a portion removed to have a different configuration than the plurality of set teeth,
- wherein the cutting edge additionally includes a third tooth counting consecutively from the first tooth that is flattened to be unset, and
- wherein the cutting edge additionally includes a second tooth counting consecutively from the first tooth, at least a portion of the second tooth being removed to form an enlarged gullet between the first tooth and the third tooth, the enlarged gullet having a first volume that is at least 1.5 times a second volume of each of the remaining gullets in the plurality of gullets.
