There is provided a reciprocating saw blade having a tapered tang stem. The tang has a tang portion with at least three outer edges and a stem portion with at least three outer edges. The profiles of the tang portion and particularly the stem portion are such that they facilitate the effective and efficient engagement of the saw blade with any of numerous different keyed or keyless chucks of reciprocating saws. The tang/stem profile also advantageously provides for increased strength for resisting failure and/or fatigue stemming from a cutting force applied to the saw blade during use.

A reciprocating saw blade, for use in a portable power reciprocating saw including a chuck for releasably engaging the saw blade, includes a tang having an elongated axis and being engageable with the chuck for attaching the saw blade to the reciprocating saw. The saw further includes a blade portion having a cutting edge that defines a plurality of cutting teeth. The cutting teeth define a repeating pattern of successive groups of teeth. Each group of teeth is less than about a half inch in length, and includes a plurality of laterally offset teeth, at least one relatively high first tooth and at least one relatively low second tooth. Prior to tooth set, the at least one relatively high first tooth is at least about 0. 002 inch higher than the at least one relatively low second tooth.

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.

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 blade defines a relatively coarse tooth pitch. 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 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 and 28, and the secondary clearance angle of the high tooth is shallower than the secondary clearance angle of the low tooth.

An improved hole saw for cutting holes having a cylindrical shape that includes, along its cutting edge, a plurality of repetitive groups of saw teeth having at least four radially displaced trailing teeth. The displacement of each trailing tooth is such that it has a substantially greater displacement than for any other tooth of said group preceding said trailing tooth. The displacement of each tooth being such that the cutting edge thereof is characterized as being movable along a cutting path different from the cutting paths of the other teeth of the group as the hole saw is rotated whereby each tooth cuts chips of uniform size. Each group of teeth may include a raker tooth having no substantial displacement with respect to the side surfaces of the hole saw. The raker tooth may be the same height or of greater height than the trailing teeth.

In a saw blade having a cutting edge defined by a plurality of teeth disposed along the blade, each tooth includes a tip, a rake face, and a curvilinear base surface. The tip of each tooth and the tip of the next consecutively disposed tooth cooperate to define a pitch distance therebetween, with the curvilinear base surface and the tip of each tooth cooperating to define a maximum gullet depth. In addition, the rake face and the curvilinear base surface of each tooth define an effective gullet radius greater than about 25% of the pitch distance, and also greater than about 55% of the maximum gullet depth.

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.
