Abstract
A method of manufacturing a reciprocating saw blade includes forming 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 method of manufacturing a reciprocating saw blade comprising:
- forming a body that extends generally along an axis with a shank end portion configured to secure the blade with a powered saw, a front end configured to enter a workpiece, a cutting edge extending between the shank end portion and the front end, and a back edge opposite the cutting edge and extending between the shank end portion and the front end;
- and
- forming the cutting edge to include an unset first tooth immediately adjacent the front end, an unset third tooth following the first tooth toward the shank end portion, an enlarged front gullet between the first tooth and the third tooth, and a plurality of additional teeth and a plurality of additional gullets following the third tooth toward the shank end portion, wherein the plurality of additional teeth are 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.
A method of manufacturing a reciprocating saw blade comprising:
- forming a body extending generally along an axis with a shank end portion configured to secure the blade with a powered saw, a front end configured to enter a workpiece, a cutting edge extending between the shank end portion and the front end, and a back edge opposite the cutting edge and extending between the shank end portion and the front end;
- and
- forming the cutting edge to include an unset front tooth immediately adjacent the front end and a plurality of additional teeth following the front tooth toward the shank end portion, 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 shank end portion, the plurality of additional teeth each being substantially the same size as each other and separated from each other by a plurality of additional gullets so that the additional teeth are spaced apart from each other by a first distance, and wherein the front tooth is spaced apart from the leading tooth by an enlarged gullet so that the front tooth is spaced apart from the leading tooth by a second distance that is greater than the first distance.
