    Abstract: A coated abrasive disc includes a disc backing and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements secured to a major surface of the disc backing by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal and vertical lines of a rectangular grid pattern. Each abrasive element has two triangular abrasive platelets, each having respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of the triangular abrasive platelets is disposed facing and proximate to the disc backing. A first portion of the abrasive elements is arranged in alternating first rows wherein the triangular abrasive platelets are disposed lengthwise aligned with the vertical lines. A second portion of the abrasive elements is arranged in alternating second rows wherein the triangular abrasive platelets are disposed lengthwise aligned with the horizontal lines. The first and second rows repeatedly alternate along the vertical lines. Methods of making and using the coated abrasive disc are also disclosed.
