The 3M™ Stikit™ Gold Paper Disc Roll 216U is a durable aluminum oxide roll constructed on a light, A-weight paper backing. The open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade and a special loading-resistant coating makes this disc a good choice when loading is a problem. 3M™ Stikit™ Gold Paper Disc Roll 216U is designed for convenience, combining open coat aluminum oxide discs with a handy adhesive backing that helps with quick and easy attachment to a 3M™ Stikit™ Disc Pad on a random orbital sander (both sold separately). This high-quality, coated abrasive product comes ready to use with a pressure sensitive adhesive (PSA) coating on the backside so they conveniently press on to the backup pad and remove cleanly—leaving an uncontaminated surface for the next disc.
