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.

A saw blade includes an elongated body with a working edge extending along a longitudinal axis. A first strip composed of carbide or cermet and including at least one first full cutting tooth is coupled to a first portion of the working edge by a first weld fusion zone composed of a ductile material. The first strip is set in a first direction at a first angle out of a plane of the body by a first bend in the first weld fusion zone. A second strip composed of carbide or cermet and including at least one second full cutting tooth is coupled to a second portion of the working edge by a second weld fusion zone composed of a ductile material. The second strip is set in a second direction, opposite the first direction, at a second angle out of the plane of the body by a second bend in the second weld fusion zone.

A saw blade for use with a reciprocating saw includes a body and an attachment portion extending from the body. The attachment portion includes a tang and an aperture configured to connect to the reciprocating saw. The saw blade also includes a cutting portion formed on the body. The cutting portion includes a plurality of cutting teeth, and first and second floor guard teeth spaced apart and positioned adjacent at least one of the plurality of cutting teeth. Each cutting tooth has a tip that defines a plane. The body has a first height measured generally perpendicularly from a back edge of the body to the plane. The attachment portion has a second height measured generally perpendicular to the plane. A ratio of the first height to the second height is between approximately 4 and approximately 5. The first and second floor guard teeth extend beyond the plane.

A saw blade can include a blade body having a cutting edge defined by multiple teeth. The teeth can be disposed in a repeating pattern including a raker tooth, a first set tooth having a light offset to a right side of the blade body, a second set tooth having a heavy offset to the left side of the blade body, a second raker tooth, a third set tooth having a light offset to the left side, and a fourth set tooth having a heavy offset to the right side of the blade body. Each tooth can include a tip, rake face, gullet having a gullet depth, and one or more clearance surfaces. The pitch distance and gullet depth of the heavy offset teeth can be less than the pitch distances and gullet depths of the remaining teeth to provide an increased amount of strength for the heavy offset teeth.

Systems and methods for milling saw blade tooth profiles and saw blades with milled tooth profiles are disclosed herein. The systems include blade milling systems that include a milling head, a blade support structure, a blade advance structure, and a control system. The methods include supporting a saw blade, advancing the saw blade, and machining a finished tooth profile in a working portion of the saw blade with an end mill. In some embodiments, the machining may include operatively translating the end mill relative to the saw blade with a milling head and within a plane that is at least substantially perpendicular to an end mill rotational axis. In some embodiments, the machining may include dry-machining the finished tooth profile in the working portion of the saw blade in a single pass. The saw blades include a plurality of teeth and may include at least one relief region.

A reciprocating saw blade includes a body including a first end portion, a second end portion opposite the first end portion, and a coupling edge extending between the first and second end portions. The body defines a longitudinal axis extending through the first and second end portions. The reciprocating saw blade also includes an attachment portion coupled to the first end portion of the body and a cutting portion coupled to the coupling edge of the body. The cutting portion includes a plurality of cutting teeth and a plurality of gullets. Moreover, the reciprocating saw blade includes a plurality of slots spaced along the cutting portion to separate the cutting portion into a plurality of cutting segments including a distal end segment adjacent the second end portion of the body. The distal end segment extends beyond the coupling edge of the body in a direction parallel to the longitudinal axis.

A reciprocating saw blade that includes an elongated blade body defining an inner end and a distal end, a cutting edge located on one side of the blade body and extending between the inner and distal ends thereof and a tang located at the inner end of the blade body. The tang projects from the blade body at an acute angle of at least about 3 relative to a line tangent to an inner end of the cutting edge. The cutting edge includes a portion defining a substantially curved contour and optionally can include at least one further portion defining a non-curved contour.

A blade for use with a reciprocating saw includes an attachment portion configured to couple to the reciprocating saw and a body extending from the attachment portion. The body includes a first portion, a tip portion, and a second portion extending from the first portion to the tip portion. The first portion has a height between about 0.625 inches and about 1.0 inches and the second portion has a height between about 0.18 inches and about 0.25 inches. The blade also includes a blunt tip formed at a distal end of the tip portion. An overall length of the blade is between about 2.4 inches and about 3.25 inches, measured from a proximal edge of the attachment portion to the blunt tip.
