Abstract

A reciprocating saw blade includes a body defining a longitudinal axis. The blade includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a protrusion and a tip spaced a first distance from the protrusion. The tip of a first cutting tooth is spaced a pitch distance from the tip of an adjacent second cutting tooth. A gullet is defined between the tip of the first cutting tooth and the protrusion of the adjacent second cutting tooth. The tip of a respective cutting tooth is spaced a tip height distance from a base of the gullet. An apex of the protrusion is spaced a protrusion height distance from the base of the gullet. The protrusion height distance is 65% to 68% of the tip height distance. The first distance is 40% to 77% of the pitch distance.
