Tough, Durable, and Heat Resistant

The 3M Cubitron II Cloth Belt 966F is a high-performance abrasive belt designed for moderate pressure applications. Its precision shaped grain (PSG) technology sets it apart from conventional abrasives, offering superior durability and heat resistance. The belt features a water resistant Z & Y-weight, polyester backing that provides excellent strength and allows for use with liquid-based lubricants. Whether used in wet or dry applications, the 966F cloth belt delivers exceptional performance and longevity.

The Science of 3M Precision Shaped Grain

The precision shaped grain (PSG) used in the 3M Cubitron II Cloth Belt 966F represents a significant advancement in abrasive technology. Developed through a proprietary process, PSG is a ceramic mineral that enhances the toughness and hardness of the grain. What sets PSG apart is its unique triangular shape, engineered to continually fracture into super-sharp points and edges. This slicing action, as opposed to gouging or "plowing" like conventional abrasives, results in a super-fast cut with reduced heat build-up. The PSG also stays cooler and sharper, leading to longer-lasting performance compared to conventional abrasives.

Get the Belt You Need

3M offers a wide range of abrasive belts to suit various metalworking applications. These belts come in different widths and lengths, catering to the needs of different belt sanding tools. For flat finishing, wide belts are used with wide belt sanders to remove and smooth rough cut metal sheets or slabs, as well as to add a grain pattern to stainless steel sheets. Medium-width belts are typically used on a backstand for tasks such as weld removal or removing casting gate.
