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

  1. What is the 3M™ Paper Belt 364UZ made of?

    The 3M™ Paper Belt 364UZ is made of aluminum oxide abrasive and a F-weight paper backing.

  2. What size does it come in?

    It comes in a size of 52 inches x103 inches.

  3. How many belts are included in one case?

    There are five belts included in each case.

  4. Is this belt compatible with all types of sanding machines or only specific ones?

    This particular product uses a specialty Sine-lok technology, which is compatible with certain sanding machines. You should check your machine's specs to see if it is appropriate for use with the Sine-lok system

  5. Can you describe what Sine-Lok, Full-flex mean and how this benefits me as a customer?

    - Sure! "Sine-lok" refers to the type of attachment method that allows for fast and easy changing but locks securely into place when running so belts don't randomly release. And "Full-flex" means that the belt has superb flexibility which gives it better conformability to contours, curves or other shapes. Together they make sure you'll be able to get long lasting performance out of your abrasives while making quick adjustments so you can stay focused on getting your work done efficiently!

The paper backing of 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 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.
