ABSTRACT:
An abrasive article comprising a binder and abrasive grits, wherein the abrasive grits comprise abrasive particles having specified shapes. Coated abrasive articles of this invention comprise a backing having at least one layer of abrasive material adhered thereto by means of a binder. A portion of this layer contains abrasive particles having specified shapes. It is preferred that the geometric shape of these abrasive particles be triangular. For triangular-shaped particles, about 35% to about 65% of the particles are oriented with a vertex pointing away from the backing and a base in contact with the binder, with about 35% to about 65% of the particles being oriented with a base pointing away from the backing and a vertex in contact with the binder. It is believed that this configuration brings about the result that the sum of the surface areas of each of the particles in contact with the workpiece remains essentially constant during use, even though the surface area of each individual abrasive particle in contact with the workpiece varies during use. The use of the abrasive particles described herein minimizes the formation of flat surfaces on the cutting regions of the abrasive grits.
