3M Cubitron II Cloth Belt 784F features 3M Precision-Shaped Grain for longer life and a faster, more consistent cut than conventional ceramic aluminum oxide belts. A precise mix of shaped ceramic and premium aluminum oxide delivers optimal cut in medium-pressure grinding and blending applications. The belt also features a waterproof backing and grinding aid.

Outstanding Performance on Medium Pressure Applications
We engineered our 3M Cubitron II Cloth Belt 784F with medium pressure industrial applications in mind, using 3M Precision-Shaped Grain, which cuts exceptionally fast and self-sharpens during grinding. This high-performing belt contains a ceramic and aluminum oxide blend that delivers cost-effective performance on medium-pressure applications, where a full ceramic belt may be underutilized.

Coarse grades 36-80 have a YF-weight backing, while finer grades of 120-180 have a lighter XF-weight backing. Both weights are moderately flexible and conform well to slight contours and flat surfaces.

Ideal for Robotic Grinding and Degating
In medium and high-pressure applications like robotic grinding, it's important to choose a premium abrasive belt like the fast-cutting, long-lasting 3M Cubitron II Cloth Belt 784F. The mineral in the belt continually fractures into sharp edges to keep cutting through the life of the belt, reducing changeouts and downtime in robotic cells. This helps maximize the efficiency of the cell, allowing you to produce more parts per belt.

Run it Wet or Dry
With its water-resistant polyester backing, 3M Cubitron II Cloth Belt 784F may be run wet or dry. To protect heat sensitive alloys such as stainless steel, titanium, nickel alloys and cobalt alloys from heat-related stress cracks and discoloration, we incorporated a grinding aid to help reduce grinding temperatures. Additionally, the abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure.

The Science of 3M Precision-Shaped Grain Blend
3M Precision-Shaped Grain is a major advancement in abrasive technology. This ceramic mineral is designed using a proprietary process to enhance toughness and hardness of the grain. 3M scientists then went one step further and engineered the mineral to form uniform triangular shaped grains that continually fracture into super-sharp points and edges that slice through the substrate, rather than gouging or "plowing" like conventional abrasives. It creates a super-fast cut and lessens heat build-up on the workpiece, reducing heat-related stress cracks and discoloration. Moreover, because 3M Precision-Shaped Grain stays cooler and sharper, it lasts longer than conventional abrasives.

Engineered for Demanding Industrial Environments
For more than 100 years 3M has been a leading abrasive supplier of the metalworking industry. With a wide combination of minerals, backings and bonds, regardless of your grinding and finishing applications, 3M offers a full line of quality coated and bonded abrasives. The exceptionally fast cut and long life of 3M Precision Shaped Grain makes it ideal for industrial environments. Trust 3M Cubitron II Cloth Belt 784F to produce immediate, uniform results over the life of the product on all metals, including heat-sensitive alloys.

Trusted 3M Cubitron II

The 3M Cubitron II Cloth Belt 784F offers reliable performance with 3M Precision-Shaped Grain technology. This blend delivers a faster, more consistent cut than traditional ceramic aluminum oxide belts, making it a smart choice for medium pressure grinding.

Medium Pressure Grinding

This belt is engineered for medium pressure applications, featuring a YF-weight backing for coarse grades 36-80 and a lighter XF-weight backing for finer grades 120-180. This backing flexibility helps the belt conform to both flat and contoured surfaces.

With dimensions of 2 inches by 60 inches, the belt fits a variety of grinders. Its design supports consistent performance on medium pressure tasks, improving productivity and throughput in metalworking operations.

Wet Or Dry Use

The 3M Cubitron II Cloth Belt 784F includes a Film-lok waterproof backing, allowing it to be used in both wet and dry grinding environments. This versatility helps protect heat-sensitive alloys like stainless steel and titanium from heat damage.

A grinding aid incorporated into the belt reduces heat buildup during use, preventing stress cracks and discoloration. This feature extends belt life and maintains workpiece quality under various conditions.

Robotic Grinding Efficiency

Ideal for robotic and pressure-assisted grinding, this belt reduces downtime by maintaining sharp cutting edges throughout its life. The mineral continually fractures to create new sharp points, enhancing cutting speed and belt longevity.

Its single-flex design supports smooth operation in automated cells, helping manufacturers produce more parts per belt. The 50 belts per case pack size ensures a steady supply for high-volume production.

Durable Size And Format

The belt measures 2 inches by 60 inches, a common size for many industrial grinders. Its cloth belt format provides durability and flexibility, suitable for demanding metalworking tasks.

Packaged in cases of 50, the 3M Cubitron II Cloth Belt 784F offers convenience and value for continuous use. The Film-lok system ensures the abrasive stays firmly bonded, even under high heat and pressure.
