3M Cubitron sanding belts

3M sanding belts can be divided into four categories:

Cubitron2 sanding belts

Almost every grade of 3M abrasive belt contains the Cubitron II abrasive mineral to a greater or lesser extent. On several of our pages, you can read more about the benefits and how this unique abrasive grain works. For example, take a look at our brand page about Cubitron II.

In brief, the main advantages of the CubitronII grain are:

• fast and clean grinding
• Less dust
• Cooler grinding, less heat input
• Longer lifespan

3M™ Cubitron™ II Sanding Belt 726A

‍

3M™ Cubitron™ II Abrasive Belt 726A is widely used for blending and finishing metal. Grit sizes range from 80+ to 400+. Suitable for robotic, manual, and automated processes.

The 3M™ Cubitron™ II Abrasive Belt 726A is designed to deliver exceptional value for a variety of finishing applications. It offers fast cutting action, long life, and flexibility that better follows curves and contours. The blend of 3M Precision-Shaped Ceramic abrasive and aluminum oxide cuts quickly and stays sharp, ensuring cool cutting and long-lasting performance on most metals. All at an affordable price for everyday use!

• Affordable J-weight rear tires that can compete with J-weight AO and AZ tires
• Plant-based grinding aid offers excellent heat-resistant performance on most metals
• The abrasive contains 3M Precision-Shaped Abrasive. It cuts faster and lasts longer than conventional AZ and AO abrasives.
• Used for metalworking applications

The 3M™ Cubitron™ II Sanding Belt 726A is available in all sizes and performs well on long-belt machines, wide-belt machines, and even on small power file machines. View the sizes here that you can order directly from the online store. Other sizes are available upon request.

3M™ Cubitron™ 3 Abrasive Belt 1184F

‍

The 1184F sanding belt, specially developed for heavy-duty grinding. The color purple refers to the foundation of the technology used in this sanding belt, which is based on the material of the 3M Cubitron II fiber disc 1182C. This technology enables even faster material removal and gives the belt a long service life. It also generates less heat in the material, resulting in less discoloration. In this way, this new sanding belt helps increase productivity.

The 984FX Pro sanding belt is suitable for manual and automated applications.

3M Trizact sanding belts

A 3M Trizact belt consists of uniform pyramidal grains on a (flexible) backing. This self-sharpening aluminum oxide grain has a pyramid shape that expands rapidly. It is characterized by an even finish that is reproducible. The Trizact belts have a long service life and often time can be saved because steps in the grinding process can be skipped. See our customer case where we achieved great results using a Trizact belt on a deburring machine.

The coarseness of Trizact belt is indicated in a different way than a standard sanding belt. The designation starts with an A and runs from A300 to A5. Unlike a grit (K or P value), the A300 is the coarsest and roughly corresponds to a P80. The A5 is the finest and roughly corresponds to a P3000. So the lower the value, the finer the grain.

3M Scotch-Brite sanding belts

Scotch Brite abrasive belts are nonwoven belts constructed from an open synthetic web filled with abrasive minerals. The open structure reduces the risk of mistakes and discoloration of the workpiece. Scotch BRite can be used as the final step in a grinding process to achieve a beautiful matte finish.

Furthermore, Scotch Brite sanding belts can be used for light deburring, de-rusting and cleaning of surfaces.

The groves are designated by letters. The first letter indicates the mineral: an A (e.g. AVFN = Very Fine) stands for Aluminum Oxide. A universal hard grain with great cutting power and long life.

If the first letter is an S (e.g. SSFN = Super fine) then it means that the tire contains a silicon grain. This is sharper and breaks out sooner than an aluminum oxide grain. The result is a finer finish.
