Abstract: A band saw blade can include a blade body having a longitudinally extending back edge along one side and a cutting edge defined by multiple teeth on an opposing side of the blade body. Each tooth can have tip, a rake face disposed along the front side of the tooth, and a relief surface disposed along the opposing rear side of the tooth. A gullet can be disposed between each pair of teeth and can extend from the rake face of one tooth to the relief surface of the next adjacent tooth in the cutting direction. A notch can be defined by the junction of the rake face and the gullet. The rake face can be disposed at a positive angle and with the notch can promote the movement of swarf generated by the tip cutting a work piece into the gullet.

Abstract: A band saw blade may include a cutting edge defining a cutting plane and configured to engage a workpiece during movement of the band saw blade in a cutting direction, and a back edge located on an opposite side of the band saw blade relative to the cutting edge and defining a repeating back edge pattern. The back edge pattern may include, in sequential order, a ramp-down section defining an acute ramp-down angle relative to a plane parallel to the cutting plane, a first ramp-up section defining a first acute ramp-up angle relative to the plane parallel to the cutting plane, an intermediate section oriented at least substantially parallel to the cutting plane, a second ramp-up section defining a second acute ramp-up angle relative to the plane parallel to the cutting plane, and a spacing section oriented at least substantially parallel to the cutting plane.
