An abrasive comprising molded abrasive particles each having an opening. The shaped abrasive particles are formed from alpha alumina and have a first surface and a second surface separated by a thickness t. Each shaped abrasive particle opening can improve grinding performance by reducing the size of the resulting wear plane, can provide a grinding aid reservoir, and can improve the adhesion of the coated abrasive article to the backing. .
