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 materials can I use the 3M™ Paper Belt 364UZ, P150 on?

Great question! The 3M™ Paper Belt 364UZ, P150 is designed for sanding and finishing wood, MDF, particleboard, and similar substrates—perfect for woodworking shops or furniture manufacturers!
What does "Sine-lok" mean on this belt?

“Sine-lok” refers to the special joint design that provides a smoother running belt with minimal bump as it goes over your rollers. That way you get consistent results and less vibration!
Is this paper belt durable enough for heavy-duty applications?

Absolutely—it features an F-weight backing that's one of the heaviest paper backings available. This means it's strong and holds up well even in more demanding sanding jobs. You can count on both durability and performance!

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 sturdy backing provides the necessary support for demanding sanding and finishing tasks, helping to maintain consistent performance throughout the belt’s lifespan.

Open Coat Structure for Superior Dust Management

On the abrasive side, the 3M™ Paper Belt 346UZ 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 belt performance.

Innovative Sine Wave Splice for Enhanced Belt Strength

To ensure optimal finishing results, the belt ends are joined using a sine wave splice. This innovative splice design enhances the overall strength of the belt and resists hinging and fatigue at the splice point. The sine wave splice allows the belt to travel smoothly over contact wheels and platens, minimizing chatter marks and ensuring consistent, smooth operation in either direction. This results in a uniform finish and extends the usable life of the belt.

Premium Aluminum Oxide Abrasive for Versatile Performance

The 3M™ Paper Belt 346UZ utilizes a premium 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 the belt to maintain its cutting efficiency far longer than traditional abrasives like garnet, which tend to wear down quickly. Thanks to its high hardness, strength, and low heat retention, aluminum oxide is ideal for a wide range of sanding and finishing applications on both wood and metal, including ferrous alloys.

Versatile Belt Sizes for Multiple Applications

Abrasive belts are available in a variety of widths and lengths to accommodate different types of belt sanders and a broad spectrum of applications. 3M offers an extensive selection of belts to fit nearly any industrial belt sander.

Wider belts are perfect for dimensioning and sanding large wood panels, smoothing rough-cut edges of metal sheets, or imparting a grain pattern to stainless steel surfaces.
Medium-width belts are designed for use with edge or portable belt sanders, making them ideal for sanding or blending wood components such as cabinet doors.

With its combination of advanced features and high-quality materials, the 3M™ Paper Belt 346UZ delivers reliable, consistent results for a wide range of industrial sanding and finishing tasks.
