3M Paper Belt 366UZ, P120 F-weight, 6 in x 344 in, Film-lok, Full-flex, Case of 20

• 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 efficient sanding and finishing. This model features 3M's premium aluminum oxide mineral, ensuring aggressive cutting and long abrasive life.

Its Film-lok technology creates a strong joint with a smooth running belt in either direction. This makes the 366UZ reliable for consistent results in woodworking and metalworking tasks.

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 backing supports the closed coat abrasive, which offers greater grain density. This combination is ideal for sanding flat surfaces and producing finer finishes on hard woods.

Precise Size And Format

The belt measures 6 inches by 344 inches, fitting a variety of industrial belt sanders. Its size makes it suitable for sanding large wood panels or smoothing metal sheet edges efficiently.

Sold in cases of 20, this pack count ensures you have enough belts for ongoing projects. The full-flex format allows the belt to bend without cracking, extending its usability.

Advanced Dust Management

Anti-static treatment on the 366UZ helps manage dust and loading during sanding. This reduces clogging and keeps the abrasive surface effective longer.

When paired with a dust collection system, the belt’s dust management technology pulls dust away easily. This keeps your workspace cleaner and improves sanding performance.

Closed Coat Abrasive Benefits

The closed coat abrasive provides greater grain density compared to open coat belts. This results in a finer finish, especially on hard woods, making it ideal for detailed woodworking.

Using premium aluminum oxide mineral, the belt offers a tough abrasive that self-fractures to expose fresh cutting edges. This extends the belt’s life and maintains cutting efficiency.
