Abrasive article and method of forming
View Patent ↗An abrasive article can include a body including a bond material, abrasive particles contained in the bond material, and an impact modifier. In an embodiment, the impact modifier can be in a content of at least 1 vol % of and at most 10 vol % for a total volume of the body. In another embodiment, the impact modifier can include particles having an average particle size (D 50 ) of at least 10 microns, a particle size D 10 of at least 2 microns, a particles size D 90 of at most 2 mm or any combination thereof.
