Saw blade and system and method for manufacturing a saw blade

Abstract

A saw blade includes a body having a thickness, an attachment portion formed on the body, and a plurality of cutting teeth formed on the body. The attachment portion is configured to connect the saw blade to a power tool. Each cutting tooth of the plurality of cutting teeth includes a tip defining a plane that extends along the thickness of the body, a rake face extending from the tip, and a relief face extending from the tip opposite the rake face. A first cutting tooth of the plurality of cutting teeth is set in a first direction relative to the body. A second cutting tooth of the plurality of cutting teeth is set in a second direction opposite the first direction relative to the body. The planes defined by the tips of the first and second cutting teeth are generally parallel.
