Rivet cleaning disc sands and cleans around rivetsLayered construction enables access to tight anglesNon-woven fiber construction can take on tough surfaces without marring the workpieceOpen-web construction minimizes heat for effective use on steel and aluminumUse together with a 3M Roloc plus holder (sold separately) for fast and easy attachment and removalThis cleaning disc sands and cleans around rivets with high-speed efficiency and consistent results. This tough, tightly layered disc achieves a close fit against and between rivets and leaves behind a clean, consistent finish while maintaining the geometry of the workpiece. This non-woven quick change disc uses aluminum oxide as the abrasive material. It has a diameter of 4 inches. Since this product is non-woven, grade is generally used to describe the abrasiveness; with the 07410 having a medium grade. All abrasive products that rotate or spin, such as the ones in this category, have a maximum speed at which you can run them. This 3M quick change disc can be run at a maximum speed of 6000.
