摘要：
A composite abrasive filament, including at least one preformed core at least partially coated with a hardened, abrasive-filled thermoplastic elastomer, exhibits increased abrading life over previously known abrasive filaments. Also disclosed are methods of making such filaments and using such filaments in article form to abrade a variety of workpieces.
