3M Paper Belt 366UZ, P220 F-weight, 36 in x 75 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.

3M Paper Belt Model

The 3M Paper Belt 366UZ is designed for reliable performance in sanding tasks. This model features 3M's premium aluminum oxide mineral, ensuring an aggressive cut and long abrasive life.

Its construction includes a film media splice that creates a strong joint and smooth running belt in either direction. This makes the 366UZ a versatile choice for consistent finishing results.

Durable F-weight Backing

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

The F-weight backing supports efficient sanding and finishing of flat surfaces, making it ideal for woodworking applications where a smooth finish is essential.

Precise Size And Format

The belt measures 36 inches by 75 inches, fitting a range of industrial belt sanders. Its full-flex design allows it to bend and flex without cracking, enhancing its lifespan and usability.

With a pack count of 5 belts per case, this product offers convenience for ongoing projects or professional use, ensuring you have enough belts on hand for multiple sanding jobs.

Effective Dust Management

Anti-static treatment on the 366UZ helps manage dust and loading during sanding. This feature reduces static in dust particles, allowing them to be pulled away more easily when used with a dust collection system.

Such dust control improves the sanding environment and extends belt life, making the sanding process cleaner and more efficient for users.

Closed Coat Abrasive Benefits

The closed coat abrasive structure provides greater grain density, resulting in a finer finish on hard woods compared to open coat abrasives. This makes it suitable for detailed woodworking tasks.

Combined with the premium aluminum oxide mineral, the belt offers a tough, durable abrasive surface that self-fractures to expose fresh cutting edges, maintaining performance over time.
