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°.
Claims16
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,
- the top bevel surface of the first end tip, the top bevel surface of the second end tip, the first bevel surface and the second bevel surface of the first ridge tip, and the first bevel surface and the second bevel surface of the second ridge tip are each 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°.
