Abstract
The present invention provides an apparatus and method for cutting a chamfer into the edge of a material while simultaneously making another cut in the material. The chamfer provides the cut material with reduced susceptibility to top surface edge swell.
Claims20
A saw blade, comprising:
- at least one circular blade comprising cutting surfaces, wherein the circular blade is configured to cut a primary cut and at least one secondary cut into a material when rotating about an axis;
- wherein the secondary cut comprises a chamfer;
- wherein the primary cut comprises the tongue-side of a tongue-and-groove pattern, or the groove-side of a tongue-and-groove pattern;
- wherein the chamfer shares an edge with the primary cut;
- wherein the material comprises oriented strand board (OSB);
- wherein the secondary cut gives the cut material reduced susceptibility to top surface edge swell.

A saw blade, comprising:
- at least one circular blade comprising cutting surfaces, wherein the circular blade is configured to cut a primary cut and at least one secondary cut into a material when rotating about an axis;
- wherein the secondary cut comprises a chamfer;
- wherein the primary cut comprises a cut through the material, such that the primary cut comprises a cut from one side of the material to an approximately opposing side of the material;
- wherein the chamfer shares an edge with the primary cut;
- wherein the material comprises oriented strand board (OSB);
- wherein the secondary cut gives the cut material reduced susceptibility to top surface edge swell.
