3M Paper Belt 366UZ, P180 F-weight, 54 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.

3M Paper Belt Model

The 3M Paper Belt 366UZ is designed for reliable sanding performance. This model features a premium aluminum oxide abrasive that offers a strong cut rate and long life, making it a preferred choice for industrial use.

Its closed coat format enhances grain density, providing a finer finish on hard woods. The belt is constructed to resist loading and static, ensuring smooth operation during woodworking tasks.

Durable F-weight Backing

This belt uses a heavy F-weight paper backing, one of the most rigid and durable options available. The backing supports smooth operation and helps achieve finer finishes compared to cloth-backed belts of the same grade.

The sturdy paper backing also contributes to the belt’s longevity, making it suitable for demanding sanding applications on flat surfaces in woodworking.

Size And Pack Details

The belt measures 54 inches by 103 inches, providing ample surface area for sanding large panels or metal sheets. This size fits a variety of industrial belt sanders, making it versatile for different projects.

Each case contains 5 belts, offering a convenient pack size for ongoing work or multiple machines. This quantity supports efficient workflow without frequent reordering.

Sine-lok Full-flex Format

The belt features the Sine-lok full-flex format, which includes a film media splice. This splice creates a strong, smooth joint that runs quietly in either direction, reducing chatter marks during sanding.

This design ensures consistent finishing results and extends belt life by minimizing stress at the splice, making it ideal for both wood and metal sanding applications.

Anti-static Dust Control

Anti-static treatment on the 3M Paper Belt 366UZ helps manage dust and loading by reducing static charge. This allows dust particles to be pulled away more easily when used with an efficient dust collection system.

Effective dust management improves sanding quality and keeps the work area cleaner, which is especially important in industrial environments where dust buildup can affect performance and safety.
