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 cutting tool includes a hole saw and an arbor assembly removably coupled to the hole saw. The arbor assembly includes a shank having a first end, a second end opposite the first end and configured to be coupled to a power tool, a body between the first and second ends, and an longitudinal axis extending centrally through the shank between the first and second ends. The body includes a recess. The arbor assembly also includes a sleeve supported by the shank, the sleeve including a central bore that receives the shank and a locking member positioned in the central bore, the locking member formed as a single, monolithic piece with a remainder of the sleeve, the sleeve moveable between a first position, in which the locking member engages the recess, and a second position, in which the locking member is spaced apart from the recess.

Abstract: An accessory for use with an oscillating power tool. The accessory includes an attachment portion including a mounting aperture arrangement configured to couple with the oscillating power tool. The accessory also includes a body extending away from the attachment portion in a longitudinal direction defining a longitudinal axis, a distal end portion including a generally planar surface and a cutting edge configured to perform a material-removing operation, and a conduit extending from proximate the cutting edge towards the attachment portion. The conduit is configured to convey material removed during the material-removing operation towards a vacuum system.

Abstract: A drilling tool includes a drive assembly with a shank that is configured to couple to a power tool and a step drill bit. The step drill bit includes a body having a proximal end adjacent the shank, a distal end opposite the proximal end, and a bit axis extending centrally through the body between the proximal end and the distal end. The body is defined by a wall extending around the bit axis to define a hollow interior cavity of the body. The step drill bit also includes a plurality of axially stacked, progressively sized steps with a first step at the proximal end and a terminal step at the distal end and a flute extending from the proximal end to the distal end. The flute defines a cutting edge.
