Bear-Tex Rapid Strip Discs are constructed with thick, strong synthetic fibers and extra-coarse silicon carbide abrasive. The open web construction of the disc provides fast cutting action with very little loading. Safer than wire bristle tools, THEBEAST aggressively removes rust and paint from drip moldings, pinch welds, door jambs, seams and other difficult to reach areas. The robust TR+ attachment system allows for rugged cleaning in tight areas. TR+ can be used on all competitive back-up pads utilizing a similar system.
