This assortment of inside ring sanding buffs includes four different abrasive grades—80-, 180-, 220-, and 320-grit—that are ideal to use sequentially for finishing and polishing the inside of a ring. Each buff features a center made of Scotch-Brite™ material with vertical flaps of aluminum oxide-coated sandpaper spaced evenly around the circumference; this design improves the sanding action for faster, more effective finishing. Each package of 12 buffs includes three buffs of each grit; the sanding buffs are each mounted on a 3/32" mandrel.
