  • Patent number: 10252358
    Abstract: A reciprocating saw blade includes a body defining a longitudinal axis. The saw blade includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a tip, a rake face at least partially defining a gullet, a relief surface, and a protrusion extending from an end of the relief surface. The protrusion of each cutting tooth inhibits a nail from entering the gullet. The tips of the plurality of cutting teeth define a first plane that is generally parallel to the longitudinal axis and the protrusions of the plurality of cutting teeth define a second plane that is generally parallel to the longitudinal axis. A distance between the first plane and the second plane is at most 0.035 inches, and a distance between the protrusion of one cutting tooth and the tip of an adjacent cutting tooth, measured generally parallel to the longitudinal axis, is 0.08 inches.

  • Patent number: 10189099
    Abstract: A reciprocating saw blade for use with a reciprocating saw includes a body defining a longitudinal axis and an attachment portion. The attachment portion includes a tang and an aperture configured to couple 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. Each cutting tooth including a tip, a rake face extending from the tip generally toward the longitudinal axis and at least partially defining a gullet, a relief surface extending from the tip and having a first end that is closer to the attachment portion and a second end that is further from the attachment portion, and a protrusion extending from the second end of the relief surface.

  • Patent number: 9827626
    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.
