Abstract
A cutting blade includes a body defining a longitudinal axis, an attachment portion coupled to the body, the attachment portion configured to be coupled to a power tool, and a cutting portion extending along an edge of the body parallel to the longitudinal axis, the cutting portion including a plurality of cutting teeth. Each cutting tooth includes a tip and a rake face extending from the tip, and each cutting tooth also includes a carbide insert that forms at least the tip of the cutting tooth. At least part of the cutting portion is deflectable relative to the body.
Claims20
A cutting blade comprising:
- a body defining a longitudinal axis;
- an attachment portion coupled to the body, the attachment portion configured to be coupled to a power tool;
- and
- a cutting portion extending along an edge of the body parallel to the longitudinal axis, the cutting portion including a plurality of cutting teeth, each cutting tooth including a tip and a rake face extending from the tip, each cutting tooth also including a carbide insert that forms at least the tip of the cutting tooth;
- wherein at least part of the cutting portion is deflectable relative to the body.
A cutting blade comprising:
- a body defining a longitudinal axis;
- an attachment portion coupled to the body, the attachment portion configured to be coupled to a power tool;
- a plurality of cutting teeth extending from a portion of the body, the plurality of cutting teeth defining a cutting edge of the cutting blade;
- an aperture extending in a direction principally parallel to the longitudinal axis, the aperture including a first end adjacent a first cutting tooth and a second end adjacent a second cutting tooth axially offset from the first cutting tooth, the second end being closer than the first end to the attachment portion;
- and
- a cantilever portion formed between the aperture and the cutting edge, extending between the first end and the second end of the aperture, and supporting some of the cutting teeth, the cantilever portion being deflectable in a direction transverse relative to the longitudinal axis.
A cutting blade comprising:
- a body defining a longitudinal axis;
- an attachment portion coupled to the body, the attachment portion configured to be coupled to a power tool;
- and
- a cutting portion extending along an edge of the body, the cutting portion including
- a first plurality of cutting teeth defining a first plane extending parallel to the longitudinal axis, and
- a second plurality of cutting teeth axially offset from the first plurality of cutting teeth and defining a second plane, the second plurality of cutting teeth supported on a cantilever portion and configured to deflect relative to the first plurality of cutting teeth, during which the first plane and the second plane are misaligned,
- wherein the cantilever portion has a base end and a free end, and wherein the base end is closer than the free end to the attachment portion.
