3M Paper Belt 366UZ, P220 F-weight, 52 in x 103 in, Sine-lok, Full-flex, Case of 5

• Anti-static treatment helps manage dust and loading
• Closed coat provides greater grain density and finer finish on hard woods than open coat abrasives
• Film media splice provides strong joint and smooth running belt in either direction
• Heavy F-weight paper backing provides durability and smooth operation
• Premium aluminum oxide mineral provides aggressive cut and long abrasive life

3M Paper Belt 366UZ is constructed with 3M's 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 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 paper backing provides smooth operation and durability. The abrasive side features a closed coat structure that provides greater grain density to achieve finer finishes than open coat belts.

This belt also features our 3M dust management technology that reduces static in the dust particles, allowing them to be pulled away more easily when coupled with an efficient dust collection system. The belt ends are joined using a film media splice; a strong secure bond consisting of a thin film-joining media that also minimizes chatter marks and ensures a smooth running belt in either direction for consistent finishing results.

Our 3M™ Paper Belt 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 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. At 3M we offer 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 and medium-width belts fit onto edge or portable belt sanders for sanding or blending wood pieces such as cabinet doors.

Trusted 3M Paper Belt

The 3M Paper Belt 366UZ is designed for professionals needing reliable sanding performance. This model features 3M's premium aluminum oxide mineral, known for its aggressive cut and long abrasive life, ensuring efficient work on various surfaces.

Its anti-static treatment helps manage dust and loading, making it easier to maintain a clean workspace. The belt is available in a pack of 5, providing good value and convenience for ongoing projects.

Durable F-weight Backing

This belt uses a heavy F-weight paper backing, one of the most rigid paper backings available. It offers durability and smooth operation, helping you achieve finer finishes compared to cloth-backed belts in the same grade.

The F-weight backing supports consistent sanding on flat surfaces, making it ideal for woodworking tasks where precision and surface quality are important.

Precise Size And Format

The belt measures 52 inches by 103 inches, fitting a wide range of industrial belt sanders. Its full-flex design allows it to bend and move smoothly during use, reducing wear and tear on the belt and sander.

Its sine-lok format ensures a secure fit and stable operation, which helps maintain consistent sanding results across different applications.

Closed Coat Grain Density

The closed coat abrasive structure provides greater grain density than open coat belts. This results in a finer finish on hard woods and other materials, making it a preferred choice for detailed woodworking projects.

Because the grains cover more surface area, the belt cuts efficiently and leaves a smoother finish, reducing the need for additional sanding steps.

Strong Film Media Splice

The belt ends are joined with a film media splice, creating a strong, smooth-running joint. This splice minimizes chatter marks and allows the belt to run smoothly in either direction for consistent finishing results.

This feature enhances the belt’s durability and performance, especially during heavy use, ensuring reliable operation over time.
