Abstract

A bonded-abrasive tool includes a matrix of an organic bond, abrasive grains dispersed in the organic bond and a grinding aid in the form of either an inorganic nonhalogenated filler or a hydrated filler. The inorganic nonhalogenated filler can react with free radicals released from the organic bond during grinding. The hydrated filler endothermically releases water. A coated-abrasive tool includes a flexible substrate, abrasive grains bonded to the flexible substrate, and an organic bond containing a grinding aid including an inorganic nonhalogenated filler or a hydrated filler coated on the substrate.
