The Pro-Graad 11 Piece Yellow Treated Cartridge Roll Buffing Polishing Kit offers a comprehensive solution for buffing and polishing tasks, featuring 10 pieces 1/2x1-1/2x1/8 Yellow Treated Cartridge Rolls and a 1/4” Shank Mandrel. Designed for use with liquid or bar buffing compounds (not included), these rolls ensure high-quality and professional results. Crafted from the same material as yellow airway buffing and polishing wheels, they deliver consistent performance. The rolls are durable and self-renewing by tightly wrapping yellow treated polishing cloth around a cylindrical core for long-lasting use. With a focus on precision and performance, the straight cylinder style of the rolls enables effective polishing in recessed and hard-to-reach areas, catering to both cut and coloring buffing and polishing applications. Their unique design guarantees consistent finishes on inside diameters, making them versatile tools for all polishing needs. Mounted on the included cartridge roll mandrel, these rolls provide superior performance, with no detail too small to polish. Ideal for accessing small, intricate spaces, they ensure a professional finish every time. NOTE: Mounting Instructions: Glued (hard) end threads onto mandrel.
