Abstract
A segmented cutting type tipped saw blade includes a first ridge tip, a second ridge tip, a first end tip, and a second end tip. A first end of the first end tip, a second end of the second end tip, a tip end of the first ridge tip, and a tip end of the second ridge tip project radially outward. A top bevel surface extending from the first end and a top bevel surface extending from the second end, a first bevel surface and a second bevel surface extending from the tip end of the first ridge tip and a first bevel surface and a second bevel surface extending from the tip end of the second ridge tip each have a top bevel angle of greater than or equal to 3° and less than or equal to 10°.
Claims18
A segmented cutting type tipped saw blade, the saw blade comprising:
- a disc-shaped metal base having a central axis of rotation, an axial thickness, and a radially outer periphery;
- and
- a plurality of circumferentially adjacent tips extending radially outward from the radially outer periphery of the metal base, the plurality of tips comprising:
- a first end tip including a tip end projecting radially outward at a first axial end of the first end tip as viewed in a circumferential direction;
- a second end tip including a tip end projecting radially outward at a second axial end of the second end tip as viewed in the circumferential direction:
- a first ridge tip including a tip end projecting radially outward at a first position between a first axial end of the first ridge tip and a second axial end of the first ridge tip as viewed in the circumferential direction;
- a second ridge tip including a tip end projecting radially outward at a second position axially positioned between a first axial end of the second ridge tip and a second axial end of the second ridge tip as viewed in the circumferential direction;
- and
- a third ridge tip including a tip end projecting radially outward at a third position axially positioned between a first axial end of the third ridge tip and a second axial end of the third ridge tip as viewed in the circumferential direction, wherein:
- the first end tip has a top bevel surface extending from the tip end of the first end tip to a second axial end of the first end tip and the second end tip has a top bevel surface extending from the tip end of the second end tip to a first axial end of the second end tip,
- the first ridge tip, the second ridge tip, and the third ridge tip each have a first bevel surface extending from the respective tip ends to the respective first axial ends and a second bevel surface extending from the respective tip ends to the second axial ends,
- each top bevel surface, each first bevel surface, and each second bevel surface is oriented at a top bevel angle with respect to a virtual line extending parallel to the central axis through the respective tip ends, and
- each top bevel angle is greater than or equal to 5° and less than or equal to 10°.
