Abstract
The present invention is directed to a structured abrasive article that provides an enhanced cut rate and extended productive life when abrading mild steel workpieces. This abrasive article includes a backing having a surface that contains precisely shape abrasive composites. In this invention, the abrasive composites include a binder, abrasive particles, water-insoluble metal silicate particles and a coupling agent. The selection of the combination of these components or materials in an abrasive composite provides an abrasive article having an enhanced cut rate and extended productive life when used to abrade, finish or grind mild steel, particularly under wet conditions using water or water treated with rust inhibiting agents.
