3M™ Paper Belt 366UZ is a premium abrasive belt that features F-weight paper backing, providing a smooth operation and durability. The closed coat structure of the abrasive side provides greater grain density, allowing for finer finishes than open coat belts in the same grade.

This belt also features 3M dust management technology, which reduces static in dust particles, making them easier to pull away when used with an efficient dust collection system. The belt ends are joined using a film media splice, which creates a strong, secure bond that minimizes chatter marks and ensures a smooth running belt in either direction for consistent finishing results.

The premium aluminum oxide abrasive is a popular choice among industrial professionals due to its cut-rate and long life. This mineral is tough and durable, self-fracturing to expose fresh cutting edges in use. Aluminum oxide is widely used for sanding and finishing applications due to its high cut-rate, hardness, strength, and low heat retention. It is suitable for use on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys.

Abrasive belts come in many different widths and lengths and are used on a variety of different belt sanders for many different applications on both wood and metal. 3M offers a broad selection of belts to fit most any industrial belt sander. Wider belts are used to dimension and sand large wood panels, smooth rough cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts fit onto edge or portable belt sanders for sanding or blending wood pieces such as cabinet doors.
