A recip blade has a cutting edge defining a cutting direction and a repeating pattern of cutting teeth. Each repeating pattern includes (i) a leading tooth with respect to the cutting direction that includes a rake face defining a first rake angle that is negative, and (ii) a trailing tooth following the leading tooth with respect to the cutting direction that includes a rake face defining a second rake angle that is greater than the first rake angle.

Recip blade

An accessory for oscillating power tools includes an attachment portion with a rear end couplable to an oscillating power tool and a working portion coupled to the attachment portion and extending along a tool axis. The working portion includes a cutting edge arranged asymmetrically relative to the tool axis with a leading tooth disposed at one end of the cutting edge at a first distance from the rear end, a trailing tooth disposed on an opposite end of the cutting edge at a second distance from the rear end that is less than the first distance, and a plurality of intermediate teeth between leading tooth and the trailing tooth, each disposed less than or equal to the first distance and greater than or equal to the second distance from the rear end, the cutting edge slanted at an acute angle to a line perpendicular to the tool axis.

A reciprocating saw blade includes an elongated blade body extending along a blade axis and having a rear end, a front end, a cutting edge having a plurality of teeth, a non-cutting edge opposite the cutting edge; and a tang coupled to the rear end and configured to be received in a blade holder of a powered reciprocating saw. The cutting edge includes inclined and declined cutting edge portions. The inclined cutting edge portion extends away from the blade axis and toward the front end at an acute first angle and extends from a first tooth to a second tooth. The first tooth is closer to the rear end and closer to the blade axis than the second tooth. The declined cutting edge portion extends toward the blade axis and toward the front end at an acute second angle that is greater than the first angle and extends from a third tooth to the first tooth. The first tooth is closer to the front end and closer to the blade axis than the third tooth.

Reciprocating saw blade

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 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.

Reciprocating saw blade with curved cutting edge

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&#xb0; 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 recip saw blade has a blade body and a cutting edge extending along the blade body and defined by a repeating pattern of two consecutive teeth. Each of the two consecutive teeth includes a primary clearance surface defining a relatively steep primary clearance angle, a secondary clearance surface defining a relatively shallow secondary clearance angle, a tip, a rake face located on the opposite side of the tip relative to the primary clearance surface, a gullet defining a depth, a first gullet radius located on an opposite side of the gullet relative to the rake face, and a second gullet radius located between the gullet and the rake face, wherein the depth of the gullet is greater than the second gullet radius.

Saw blade with robust tooth form

A saw blade including cutting teeth, having at least one of chip-limiters protruding from the teeth or secondary teeth in the gullets of the cutting teeth configured to mitigate the blade from over-feeding. The chip limiters and/or secondary teeth provide that only a limited portion of an object that the saw blade encounters during cutting falls below the cutting tips of the cutting teeth. The chip limiters and/or secondary teeth also assist the cutting teeth in cutting.

Saw blade with feed limiter

A recip saw blade has a blade body and a cutting edge extending along the blade body and defined by a repeating pattern of two consecutive teeth suitable for abusive cutting applications. The two consecutive teeth, which may be bi-metal, include a high tooth and a relatively low tooth in comparison to the high tooth. Each high tooth and low tooth include a primary clearance surface defining a relatively shallow primary clearance angle that is about 28&#xb0; or less, and a secondary clearance surface defining a relatively steep secondary clearance angle in comparison to the primary clearance angle. The primary clearance angle of the high tooth is steeper than the primary clearance angle of the low tooth, such as between about 23&#xb0; and 28&#xb0;, and the secondary clearance angle of the high tooth is shallower than the secondary clearance angle of the low tooth.
