Abstract
A wood cutting band saw blade includes a band having a continuous band portion and having on at least one length-wise edge a plurality of teeth. The plurality of teeth extend upward from the continuous band portion, and the length-wise edge extends in a horizontal direction. Each tooth includes a cutting edge and a back angle edge defining a tip. Each tooth also includes a gullet having a forward edge extending upward from a location at a lowest extent of the gullet to the back angle edge. The gullet further includes a rearward edge extending upward from a vertical level at the lowest extent of the gullet to a cutting edge of an adjacent tooth. The location at the lowest extent of the gullet is closer to the tip than to a tip of the adjacent tooth.
Claims15
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 along a horizontal axis;
- 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 upward from a location at a lowest extent of the gullet to the back angle edge, the gullet further comprising a rearward edge extending upward from lowest extent of the gullet to a cutting edge of an adjacent tooth;
- wherein the location at the lowest extent of the gullet is closer to the tip than to a tip of the adjacent tooth;
- and
- wherein the cutting edge has a steeper average angle from the horizontal axis than an average angle of the back angle edge from the horizontal axis.
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 having a forward edge and a rearward edge, the forward edge extending from the back angle edge to a location at a lowest extent of the gullet, and the rearward edge extending monotonically upward from the lowest extent of the gullet to a cutting edge of an adjacent tooth;
- wherein the rearward edge of the gullet is longer than the forward edge of the gullet;
- and
- wherein an average angle of the back angle edge from the horizontal axis is less than an average angle of the forward edge from the horizontal axis.
