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.

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

PRODUCT FAQ

What kind of surfaces can I use the 3M™ Paper Belt 364UZ, P150 on?

Absolutely! The 3M™ Paper Belt 364UZ, P150 is great for sanding wood and other similar materials. It’s commonly used in woodworking applications to give you a smooth, consistent finish.
What does "F-weight" mean in this product's description?

Great question! “F-weight” refers to the thickness and strength of the paper backing on the belt. F-weight is a heavier, more durable paper, making it ideal for tough jobs where you need extra support during sanding.
Can I use this belt with any sander that fits its size?

Yes—if your sander uses belts sized at 52 inches by 103 inches with a Sine-lok attachment system, you’re good to go! Just double-check your machine’s specs to ensure compatibility. If you have questions about fitment, I'd be happy to help check for you!

Durable Paper Backing for Smooth Operation

The 3M™ Paper Belt 346UZ is engineered with a robust paper backing that ensures both smooth operation and long-lasting durability. This carefully selected backing material provides the necessary support for demanding sanding applications, helping to maintain consistent performance and extend the life of the belt even under rigorous use.

Open Coat Structure for Superior Dust Management

On the abrasive side, the 346UZ belt features an open coat construction. This design leaves space between the abrasive grains, which helps to minimize clogging and loading—especially when working with softer woods. The open coat structure, combined with 3M’s advanced dust management technology, significantly reduces static cling in dust particles. When paired with an effective dust collection system, this allows for more efficient evacuation of dust, resulting in a cleaner work environment and improved sanding performance.

Innovative Sine Wave Splice for Enhanced Belt Strength

To ensure optimal finishing results, the ends of the 3M™ Paper Belt 346UZ are joined using a sine wave splice. This unique splice design enhances the overall strength of the belt and resists hinging and fatigue at the joint. The sine wave splice travels smoothly over contact wheels and platens, minimizing chatter marks and ensuring consistent, smooth operation in either direction. This contributes to a uniform finish and reliable performance throughout the belt’s lifespan.

Premium Aluminum Oxide Abrasive for Versatile Performance

The 346UZ belt is equipped with a high-quality aluminum oxide abrasive, a preferred choice among industrial professionals for its exceptional cut-rate and extended service life. Aluminum oxide is a tough, durable mineral that self-fractures during use, continually exposing fresh, sharp cutting edges. This self-renewing property allows it to outperform traditional abrasives like garnet, which tend to wear down more quickly. With its high cut-rate, hardness, and resistance to heat buildup, aluminum oxide is ideal for a wide range of sanding and finishing tasks.

Suitable for Multiple Substrates and Applications

Aluminum oxide abrasives are highly versatile, making the 3M™ Paper Belt 346UZ suitable for use on a variety of substrates, including both wood and metal. It performs exceptionally well on ferrous alloys and is widely used in woodworking and metalworking applications. Whether you are sanding large wood panels, smoothing rough metal edges, or adding a grain pattern to stainless steel, this belt delivers reliable results.

Wide Range of Sizes for Diverse Sanding Needs

3M offers an extensive selection of abrasive belts in various widths and lengths to accommodate nearly any industrial belt sander. Wider belts are ideal for dimensioning and sanding large wood panels, smoothing the edges of metal sheets, or finishing stainless steel surfaces. Medium-width belts are perfect for edge or portable belt sanders, making them suitable for tasks such as sanding or blending cabinet doors and other wood components.
