Wood cutting band saw blade

A wood cutting band saw blade that when cutting wood produces saw dust and forms a kerf, comprising:

• a cutting edge defined by a plurality of teeth spaced relative to each other, and a back edge including a substantially planar portion located on an opposite side of the band saw blade relative to the cutting edge, the plurality of teeth comprising a plurality of set teeth, each set tooth defining a tip, a bend plane from which the set tooth is set, the bend plane extending substantially parallel to the substantially planar back edge portion of the band saw blade, and a shelf located on a front portion of each set tooth with respect to a cutting direction of the band saw blade and exposed during cutting, the shelf located at least partially between the tip and the bend plane and at least a portion of the shelf being planar and extending substantially parallel to the substantially planar back edge portion being planar and extending at an angle in a direction that is opposite the cutting direction and generally toward the back edge of the band saw blade for reducing saw dust passing to the kerf and accumulating on the band saw blade, wherein:
• each of the set teeth has a dimension (S1) defined as the distance between the tip and the shelf of the respective set tooth;
• each of the set teeth has a dimension (B) defined as the distance between the tip and the bend plane of the respective set tooth;
• and
• a ratio of S1/B is within the range of approximately ¼ to approximately ¾.

• wherein
• each of the set teeth comprises a relief surface and a cutting surface, the relief surface extending from one side of the tip in a direction opposite that of the cutting direction of the band saw blade and terminating at one end of an intermediate surface, and the cutting surface extending from another side of the tip;
• the shelf comprises a shelf surface extending from the cutting surface and terminating at another end of the intermediate surface;
• and
• the shelf surface comprises a first portion that is planar and generally parallel to the substantially planar back edge portion and a second planar portion that is disposed at an acute shelf surface angle that extends in a direction opposite the cutting direction and generally toward the back edge of the band saw blade.

A wood cutting band saw blade that generates dust during cutting of wood, the band saw blade comprising:

• a base having a back edge including a substantially planar portion;
• a cutting edge defined by a plurality of teeth spaced relative to each other and being located on an opposite side of the band saw blade relative to the back edge, the plurality of teeth comprising a plurality of set teeth, each set tooth defining a tip, a bend plane from which the set tooth is set, the bend plane extending substantially parallel to the substantially planar back edge portion of the band saw blade, and first means for reducing saw dust passing to a kerf and accumulating on the band saw blade, the first means being located on a front portion of each set tooth with respect to a cutting direction of the band saw blade and exposed during cutting, and being located at least partially between the tip and the bend plane, and at least a portion of the first means being planar and extending substantially parallel to the substantially planar back edge portion or at least a portion of the first means being planar and extending at an angle in a direction that is opposite the cutting direction and generally toward the back edge of the band saw blade, wherein:
• each of the set teeth has a dimension (S1) defined as the distance between the tip and said first means of the respective set tooth;
• each of the set teeth has a dimension (B) defined as the distance between the tip and the bend plane of the respective set tooth;
• and
• a ratio of S1/B is within the range of approximately ¼ to approximately ¾.
