Abstract
A wood cutting band saw blade includes a plurality of teeth extending upward from a continuous band portion. Each tooth includes a cutting edge and a back angle edge defining a tip, and a gullet. The gullet includes a forward edge extending from the back angle edge to a lowest point of the gullet, and a rearward edge extending upward from the lowest point to a cutting edge of an adjacent tooth. In some embodiments, the lowest point of the gullet is closer to the tip than to a tip of the adjacent tooth.
Claims14
A wood cutting band saw blade, comprising:
- a band having a continuous band portion and having on at least one length-wise edge a plurality of teeth, the plurality of teeth extending upward from the continuous band portion, the at least one length-wise edge extending in a horizontal direction;
- each tooth of the plurality of teeth including a cutting edge and a back angle edge defining a tip, and each tooth including a gullet, the gullet having a forward edge extending from the back angle edge to a lowest point of the gullet, and a rearward edge extending upward from the lowest point to a cutting edge of an adjacent tooth;
- and
- wherein the lowest point of the gullet is closer to the tip than to a tip of the adjacent tooth;
- wherein the back angle edge defines an average first angle from the horizontal direction and has a first length;
- wherein the forward edge of the gullet defines an average second angle from the horizontal direction over a second length, the second length at least as long as the first length;
- and
- wherein the average second angle is at least approximately twice the average first angle.
