For use with The Stripper (No. DFX DF701) and MBX Metal Blaster Tools (No. DFX MBX3500). Coarse replacement MBX brush. Self cleaning bristles literally grab and rip away thick undercoating and seam sealants. Heat-hardened tips are angled and sharpened for maximum stripping power. Adhesive/undercoating does not stick to brushes.
