3M™ Paper Roll 366UZ

The 3M™ Paper Roll 366UZ is constructed with a premium aluminum oxide mineral in closed coat format. It is an anti-static product that resists loading, and is coated on a heavy F-weight paper backing to efficiently help you sand and finish flat surfaces in woodworking applications.F-weight is one of the heaviest, most rigid paper backings available and will help you achieve finer finishes than cloth backed belts in the same grade. The 3M Paper Roll 366UZ's paper backing helps it run smoothly and makes it more durable. The abrasive side features a closed coat structure that provides greater grain density to achieve finer finishes than open coat belts. The 3M Paper Roll 366UZ 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 for use on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys.
