Active filler for abrasive tool, its use and the abrasive tool containing the same

摘要

Grinding tools usually comprise an abrasive filler (8). It is proposed that, as the abrasive filler (8), sodium chloride be used which is at least very largely free of magnesium and which is non-hygroscopic, the sodium chloride (9) preferably being provided with a coating (10) made of synthetic resin to protect it against being etched by water.
