Abstract
A saw blade including a body, a plurality of cutting teeth, and a plurality of gullets. The plurality of cutting teeth formed on the body. Each cutting tooth includes a first end and a second end. The plurality of gullets is formed between the plurality of cutting teeth. Each gullet having an opening defined between the first end of one tooth of the plurality of cutting teeth and the second end of an adjacent tooth of the plurality of cutting teeth. Each opening has an opening width and a gullet width. A ratio between he gullet width over the opening width is greater than or equal to 1.2:1.
Claims17
A saw blade comprising:
- a body defining a longitudinal axis;
- a plurality of cutting teeth formed on the body and defining a linear edge that is parallel to the longitudinal axis, each cutting tooth including a first end and a second end;
- a plurality of gullets formed between the plurality of cutting teeth, each gullet having an opening defined between the first end of one tooth of the plurality of cutting teeth and the second end of an adjacent tooth of the plurality of cutting teeth, each opening having an opening width, each gullet further having a gullet width;
- and
- a plurality of cutting inserts mounted on the linear edge outside of the plurality of gullets;
- wherein a ratio between the gullet width over the opening width that is greater than or equal to 1.2:1.
A saw blade comprising:
- a body;
- a plurality of cutting teeth formed on the body, each cutting tooth including a tooth body having a first end and a second end;
- a plurality of cutting inserts mounted to the plurality of cutting teeth, each cutting insert having a rake face, the plurality of cutting teeth and the plurality of cutting inserts forming a linear cutting edge;
- and
- a plurality of gullets formed between the plurality of cutting teeth, each gullet being generally circular and having a gullet width that is greater than an opening width of an opening between adjacent tooth bodies, the opening width being measured between the first end and the second end of the adjacent tooth bodies, each gullet forming a first undercut portion under the first end of one tooth body with respect to the rake face of a corresponding cutting insert mounted to the one tooth body and a second undercut portion under the second end of an adjacent tooth body with respect to the rake face of a corresponding cutting insert mounted to the adjacent tooth body.
A method of manufacturing a saw blade, the method comprising:
- providing a saw blade body defining a longitudinal axis;
- forming a plurality of cutting teeth defining a linear edge that is parallel to the longitudinal axis in the saw blade body, each cutting tooth including a first end and a second end such that an opening width is defined between the first end of one cutting tooth and the second end of an adjacent cutting tooth;
- forming a plurality of gullets in the saw blade body between the plurality of cutting teeth, each gullet having a gullet width such that a ratio of the gullet width over the opening width is greater than or equal to 1.2:1;
- and
- mounting a plurality of cutting inserts mounted on the linear edge outside of the plurality of gullets.
