These 4 Pcs 5-In (125mm) wool buffing wheels are felt flap discs made for the final polishing stage when you want a high gloss or mirror finish. Designed to be used on an angle grinder, they work well on stainless steel, aluminum, automotive work, non-ferrous metals, and stone surfaces.
Built with premium wool/felt and a reinforced fiberglass backer, the flap disc is intended to withstand high pressure and help absorb vibration. This supports smoother, more balanced buffing results, especially when polishing different surface shapes and sizes.
The disc uses a layered design of small felt pieces, which is stated to perform better than a solid wool disc. It can also help dissipate heat during working, making it suitable for polishing tasks where temperature buildup matters. Each disc measures Dia x H: 4-1/2" x 13/16" with a 7/8" arbor hole, and the package includes 4pcs.
