Abstract
A circular saw blade includes an arbor located in a center of the body, a bore positioned in the arbor and configured to fit on a power tool shaft, a plurality of cutting teeth spaced along an outer edge of the body, and a plurality of openings formed in the body between the plurality of cutting teeth and the arbor. The plurality of openings includes a first opening and a second opening disposed radially inward from the first opening relative to the center of the body. The second opening at least partially overlapping the first opening in a circumferential direction, a radial direction, or both.
Claims31
A circular saw blade comprising:
- a body;
- an arbor located in a center of the body;
- a bore positioned in the arbor and configured to fit on a power tool shaft;
- a plurality of cutting teeth spaced along an outer edge of the body;
- and
- a plurality of openings formed in the body between the plurality of cutting teeth and the arbor, the plurality of openings including a first opening and a second opening disposed radially inward from the first opening relative to the center of the body, the second opening at least partially overlapping the first opening in a circumferential direction, a radial direction, or both.
A method of manufacturing a circular saw blade, the method comprising:
- providing a body;
- forming an arbor in a center of the body, the arbor having a bore configured to fit on a power tool shaft;
- forming a plurality of cutting teeth along an outer edge of the body;
- welding a plurality of inserts to the plurality of cutting teeth, each insert forming a tip of a corresponding cutting tooth;
- and
- applying a coating via physical vapor deposition to at least the plurality of inserts after the plurality of inserts is welded to the plurality of cutting teeth.
