Featuring our exclusive Trizact™ technology for uniform and consistent finish, our 3M™ Trizact™ performance sanding abrasive disc makes refined, professional sanding faster and easier. This durable disc features Trizact™ mineral abrasive tiny, sharp structures resembling pyramids which are arranged uniformly across the surface. These structures create a fast, even cut that removes very fine sand scratches from metal surfaces. A foam backing makes the disc conformable for excellent consistency even around contours. This P3000 grade disc is so precise it is even recommended for creating refined, scratch-free finishes to stainless steel. And the Hookit™ hook and loop feature on the back makes it fast and easy to apply the disc to your sanding tool when used with 3M™ Hookit™ backup pads.
