Abstract
A novel approach to a commercial circular saw blade designed for efficient lumber cutting as well as extended saw blade life because of a reduction in friction and better heat dispersion. The saw plate has thicker body transitioning to a thinner rim at a point between the bottom of the gullet and the bottom of the tooth, generally occurring at the hook of the gullet. This design increases the lateral stiffness of the blade, improves accuracy, maximizes sawdust ejection, eliminates blade wandering, decreases the amount of the cut waste and allows for increased cutting speeds without decreasing the performance or longevity of the blade. This design goes against traditional, prior art saw blade design because of its interpretation of wood physics, blade friction and side clearance tolerances.
Claims9
A circular saw plate comprising:
- a circular disk having two planar sides, a center and an outer peripheral edge;
- a ring of radially spaced teeth formed around said outer peripheral edge, each tooth of said ring of teeth having a tip and a leading edge residing between and perpendicular to said planar sides;
- a ring of radially spaced gullets formed as a ring of cutouts between adjacent said teeth, each of said gullets having a linear portion beginning at said tip, a curved hook portion that meets said linear portion at a hook initiation point, and a bottom;
- a thin rim with a first cross-sectional thickness formed on said saw plate, said thin rim beginning at said outer peripheral edge and extending to a transition ring;
- a saw plate body with a second cross-sectional thickness formed on said saw plate, said saw plate body beginning at said transition ring and extending inward toward said center;
- and wherein said transition ring connects said thin rim and said saw plate body, with said thin rim said transition ring and said saw plate body all concentric;
- wherein said second thickness is larger than said first thickness;
- and wherein said transition ring is located between said bottom of said ring of gullets and said outer peripheral edge.
A circular saw blade comprising:
- a saw plate made of a circular disk having two planar sides, a center and an outer peripheral edge;
- a ring of radially spaced teeth formed around said outer peripheral edge, each tooth of said ring of teeth having a tip and a leading edge residing between and perpendicular to said planar sides;
- a ring of radially spaced gullets formed as a ring of cutouts between adjacent said teeth, each of said gullets having a linear portion beginning at said tip, a curved hook portion that meets said linear portion at a hook initiation point, and a bottom;
- and
- wherein said gullet bottom has a first thickness that exceeds a second thickness of said linear portion.
