Patent number: 10252358Abstract: 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.Type: GrantFiled: August 3, 2017Date of Patent: April 9, 2019Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Robert W.
