Abstract
Disclosed are cutting blades for cutting tools and methods of making the blades. Such blades include tooth patterns with both set and non-set teeth. Each of the set teeth are set at an angle with respect to the jaw line of the blade, and each set tooth includes at least one surface feature that is effective to direct a portion of swarf that is produced via the cutting action of the blade into gullets of the blade such that less swarf overall is directed to the cutting surface of the objects being cut by the blade.
Claims22
A cutting blade for a power driven cutting tool, comprising:
- a jaw line;
- a plurality of set teeth, wherein each set tooth includes a tooth face and further includes a tip located a predetermined distance above the jaw line, and wherein at least two of the plurality of set teeth are set in different directions with respect to a longitudinal axis of the cutting blade such that each of the at least two of the plurality of set teeth forms a positive face angle;
- and
- at least one surface feature ground into the cutting face of at least one of the plurality of set teeth, wherein each surface feature is located between the tip of the tooth on which it is defined and the jaw line of the blade.
A cutting blade for a power driven cutting tool, comprising:
- a jaw line;
- a pattern of teeth, wherein each tooth includes a tip located a distance above the jaw line, the pattern including:
- a plurality of teeth set at an angle with respect to the jaw line, at least two of the set teeth being set to different sides of the jaw line, and
- a plurality of non-set teeth, each of which is substantially aligned with the jaw line;
- at least one surface feature defined on at least one of the plurality of set teeth, wherein each surface feature is located between the tip of the tooth on which it is defined and the jaw line of the blade;
- and
- a predetermined grinding pattern defined between each surface feature and the tip of each tooth on which a surface feature is defined.
A cutting blade for a power driven cutting tool, comprising:
- a jaw line;
- a plurality of teeth set at an angle with respect to the jaw line, wherein each set tooth includes a tip located a predetermined distance above the jaw line;
- and
- at least one surface feature defined on at least one of the plurality of set teeth, wherein each surface feature is located between the tip of the tooth on which it is defined and the jaw line of the blade, and wherein each of the set teeth on which a surface feature is defined includes a grinding pattern on at least a portion of the tooth located between the tip of the tooth and the surface feature.
