3M 784F Cubitron II Knife Grinding Cloth Belt 50mm x 780mm (Pack of 12 – Various Grits Available)

• 3M Precision Shaped Grain blend provides up to 2x longer life than comparable aluminum oxide belts, which means a lower cost per part and less time lost to belt changeovers
• Proprietary mineral blend provides consistent, faster results on medium pressure applications, increasing production rate
• Moderately flexible backing provides conformability for grinding and blending both straight and contoured surfaces
• For optimal durability ...and price value, YF weight polyester backing is used for Grades 36-80, while lighter XF weight polyester backing is used for Grades 120-180
• Grinding aid cools abrasive processes on heat-sensitive alloys
• Suitable for wet and dry applications on all metals
• Durable resin bond resists deterioration from heat, extending the life of the abrasive cloth

3M™ Cubitron™ II Cloth Belt 784F features 3M Precision Shaped Grain for longer life and a faster, more consistent cut than 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 
3M™ Cubitron™ II Cloth Belt 784F is engineered with medium pressure industrial applications in mind. Made with 3M Precision Shaped Grain (PSG), the abrasive cuts exceptionally fast and self-renews 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. 

Lasts up to 2x as long as conventional ceramic aluminum oxide belts

Water and Heat Resistant Versatility 
With its water-resistant polyester backing, Cubitron™ II Belt 784F may be run wet or dry. It includes a grinding aid to help reduce grinding temperatures and protect heat sensitive alloys such as stainless steel, titanium, nickel alloys and cobalt alloys from heat-related stress cracks and discoloration. 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 signifies a major advancement in abrasive technology. PSG is a ceramic mineral 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. PSG creates a super-fast cut and lessens heat build-up on the workpiece, reducing heat-related stress cracks and discoloration. Moreover, because PSG stays cooler and sharper, it lasts longer than conventional abrasives.
