Abstract: Embodiments of the disclosure relate to a reciprocating saw blade. The reciprocating saw blade includes a body having a first end, a second end spatially disposed from the first end, a spine edge, and a cutting edge opposite to the spine edge. The reciprocating saw blade also includes a plurality of teeth defining a cutting portion of the cutting edge. Each tooth of the plurality of teeth includes a base having a unitary construction with the body. The base is made of a first material having a first hardness. A tip is welded to the base, and the tip is made of a cemented ceramic material having a second hardness that is greater than the first hardness. The cemented ceramic material includes tungsten carbide particles and at least 3 wt % of other particles including one or more cubic carbides.

Abstract: A saw blade includes an elongated blade body having a first end portion, a second end portion, and a cutting edge portion. An exposed first tool holder portion is coupled to the first end portion and is configured to removably mount the blade body in a blade holder of a powered saw. An unexposed second tool holder portion is defined by a first score in the blade body between the first end portion and the second end portion. The first score is configured so that the second tool holder portion can be exposed by breaking off a first removable portion of the blade body at the first score. The second tool holder portion is configured to removably mount the blade body in a blade holder of a powered saw when the second tool holder portion is exposed.

Abstract: A spider hub pole retaining assembly may include a hub, poles and a retainer. The hub may include channels extending radially outward in a plane. The poles maybe pivotably coupled to the hub near a center of the hub so as to be pivotable between a first position in which the poles extend radially outwardly through the channels in the plane and a second position in which the poles extend away from the outside of the channels. The retainer may include a top rotatably supported by the hub and hooks extending from the top. The top is rotatable between a retaining position in which the hooks receive the poles when the poles are in the first position and a releasing position in which the hooks are angularly offset with respect to the channels to facilitate withdrawal of the poles from the channels.

Abstract: A saw blade comprises a blade backer with a pair of side surfaces that extend substantially parallel to each other. An intermediate surface extends between the pair of side surfaces of the blade backer. A plurality of teeth extends from the intermediate surface. At least one of the teeth is located entirely within planes containing the side surfaces of the blade backer. A tip is formed at an apex end portion of the one tooth. A leading face surface of the tip on the one tooth is disposed at an acute angle relative to a plane extending perpendicular to the planes containing the side surfaces of the blade backer.

Abstract: 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 a floor guard tooth positioned adjacent at least one of the plurality of cutting teeth. Each cutting tooth has a tip that defines a plane. The floor guard tooth extends from the body beyond the plane. The attachment portion is offset from the plane to reduce interference of the reciprocating saw with a surface while performing a footer cut with the saw blade. The floor guard tooth contacts the surface while performing the footer cut to inhibit the plurality of cutting teeth from contacting the surface.
