3M Paper Roll 364UZ is constructed with premium aluminum oxide mineral. It resists loading with an open-coat construction and is coated on an F-weight paper backing to efficiently sand and finish. F-weight is one of the heaviest, most rigid paper backings available and will achieve finer finishes than cloth backed sheets in the same grade.

Heavy Backing and Dust Management
The F-weight backing of our 3M™ Paper Roll provides smooth operation and durability. The abrasive side features an open coat structure. The open coat construction resists loading better than closed coat sheets, particularly on soft wood. This product also features our 3M dust management technology that reduces static cling in the dust particles, allowing them to be pulled away when coupled with an efficient dust collection system.

Fast Cut, Long Life
The 3M™ Paper Roll features a premium aluminum oxide abrasive, which is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used for sanding and finishing applications. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys.
