3M Paper Belt 366UZ, P220 F-weight, 37 in x 75 in, Sine-lok, Full-flex, 5 ea/Case

• 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 professional sanding tasks. This model features 3M's premium aluminum oxide mineral, ensuring a strong cut and long abrasive life.

Its closed coat format provides greater grain density, which helps achieve finer finishes on hard woods compared to open coat abrasives. This makes the 366UZ ideal for woodworking applications.

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 get consistent sanding results.

Compared to cloth-backed belts, the F-weight backing helps achieve finer finishes, making it a reliable choice for flat surface sanding and finishing.

Size And Pack Details

The belt measures 37 inches by 75 inches, providing ample sanding surface for large projects. This size fits a variety of industrial belt sanders used in woodworking and metalworking.

Each case contains 5 belts, making it convenient for ongoing work or multiple projects. The pack size ensures you have enough belts on hand for continuous sanding tasks.

Sine-lok Full-flex Format

The 366UZ belt features the Sine-lok full-flex format, which allows smooth running in either direction. This format reduces chatter marks and improves finishing consistency.

The film media splice creates a strong joint, ensuring the belt stays secure during use. This design enhances belt life and performance on various sanding machines.

Anti-static Dust Control

Anti-static treatment on the belt helps manage dust and loading, improving sanding efficiency. This feature works well with dust collection systems to keep the workspace cleaner.

Reducing static in dust particles allows them to be pulled away more easily, which helps maintain the belt's cutting ability and extends its lifespan during use.
