Review on Walter 13F304 Twisted Threaded Diameter by Trey Crosland

I purchased an abrasive brush for my industrial and scientific needs and this product was a complete let down. When I tried this product on metal parts, it barely made a mark and quickly lost its effectiveness after only a few uses.The bristles were frayed and twisted, leaving visible marks on my workpiece. The only pro was the price, but my time and effort was not worth the low cost. I will not be purchasing this type of product again..
