3M Paper Belt 364UZ, 52 in x 103 in, P120 F-weight, Full-Flex, 5 ea/Case

• Anti-static treatment helps manage dust and loading
• F-weight heavy paper backing provides durability and smooth operation in either direction
• Open coat provides fast stock removal
• Premium aluminum oxide mineral provides aggressive cut and long abrasive life
• Sine wave splice prevents hinging in splice area, resists fatigue, and minimizes chatter marks

3M Paper Belt 346UZ is constructed with a premium aluminum oxide mineral. It is an open coat construction for loading resistance and is coated on an F-weight paper backing to efficiently sand and finish. F-weight is one of the heaviest, most rigid paper backings available and will achieve finer finishes than cloth backed belts in the same grade.

The paper backing of our 3M Paper Belt 346UZ provides smooth operation and durability. The abrasive side features an open coat structure. The open coat construction resists loading better than closed coat belts, particularly on soft wood. This belt also features our 3M dust management technology that reduces static cling in the dust particles, allowing them to be evacuated more easily when coupled with an efficient dust collection system. To support desired finishing results, the belt ends are joined using an sine wave splice that promotes belt strength and resists hinging and splice fatigue. The splice travels smoothly over contact wheels and platens, minimizes chatter marks, and promotes smooth operation in either direction for consistent finishing results.

3M Paper Belt 346UZ 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. 3M offers 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. 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 364UZ offers reliable performance with its premium aluminum oxide abrasive. This model is designed for durability and aggressive cutting, making it a top choice for professionals. Its P120 F-weight grade ensures a balance of cut rate and finish quality.

With the Full-Flex format, this belt operates smoothly in either direction, reducing wear and tear. The 3M brand guarantees consistent quality, helping users achieve precise sanding results every time.

Durable F-Weight Backing

The belt features an F-weight heavy paper backing, known for its rigidity and durability. This backing supports smooth operation and resists damage during use, which is essential for maintaining consistent sanding performance.

F-weight backing is one of the heaviest paper backings available, providing better finishes than cloth-backed belts of the same grade. This makes it ideal for demanding sanding tasks on wood and metal.

Optimal Size And Format

Measuring 52 inches by 103 inches, this belt fits a variety of industrial belt sanders. The size allows for sanding large surfaces efficiently, making it suitable for both woodworking and metalworking applications.

Sold as 5 belts per case, this pack size ensures you have enough supply for extended projects or multiple jobs. The Full-Flex design also helps the belt conform to different sanding machines and surfaces.

Fast Stock Removal

The open coat construction of the 364UZ belt promotes fast stock removal by reducing loading and clogging. This design helps maintain cutting efficiency, especially when sanding softer materials like wood.

Anti-static treatment further enhances dust management by reducing static cling, allowing dust to be evacuated easily with a dust collection system. This keeps the work area cleaner and improves belt life.

Strong Sine Wave Splice

The belt ends are joined with a sine wave splice that prevents hinging and resists fatigue. This splice design minimizes chatter marks and promotes smooth operation over contact wheels and platens.

This feature supports consistent finishing results and extends belt life by reducing stress at the splice area. It also allows the belt to run smoothly in either direction, enhancing flexibility during use.
