  1. What does the '50+ YF-weight' mean exactly?

    The 'YF' grade stands for a high-performance, heavy-duty backing that provides superior strength and durability. The 50+ refers to the grit size.

  2. Can you tell me more about this belt's performance and lifespan?

    Cubitron II belts are engineered with precision-shaped grain technology, which cuts up to twice as fast as competitive ceramic products while also providing greater consistency and longevity. This particular belt is designed for aggressive cutting on tough metals like stainless steel and nickel alloys.

  3. Is there anything particularly unique about its construction or design?

    The Cloth Belt 966F features a versatile film-lok attachment system that makes it easy to switch between different levels of abrasive intensity when grinding or sanding. Its full-flex construction also allows it to adapt easily to curved surfaces without risking damage or uneven wear.

  4. What types of equipment is this belt compatible with?

    Our Cubitron II cloth belts can be used on most standard industrial belt sanders in conjunction with various other tools such as grinders, deburring machines, benchtop equipment, among others

  5. Q:Is there any warranty available on these belts?

    A :Yes! We offer a limited lifetime warranty against defects in workmanship and materials for our Cubitron II abrasives once they have been properly installed .

Tough, Durable, and Heat Resistant

The 3M™ Cubitron II™ Cloth Belt 966F is a high-quality abrasive belt that is designed for moderate pressure applications. The belt features precision shaped grain that ensures a super-fast cut and lessens heat build-up in the workpiece, reducing heat-related stress cracks and discoloration. The water-resistant Z & Y-weight, polyester backing gives excellent strength to the belt that allows for use with liquid-based lubricants, but can be run in a wet or dry application. These attributes make the polyester cloth 966F cloth belt a good match for projects that require an equally durable abrasive belt.

The Science of 3M™ Precision Shaped Grain

3M™ Cubitron II™ Cloth Belt 966F's precision shaped grain (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 precisely 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 in the workpiece, reducing heat-related stress cracks and discoloration. Moreover, because PSG stays cooler and sharper, it lasts longer than conventional abrasives.

Get the Belt You Need

Abrasive belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different metalworking applications. 3M offers a broad selection of belts to fit most industrial belt sanders. Wider belts are used with wide belt sanders for flat finishing—to remove and smooth rough cut metal sheets, slabs or add a grain pattern to stainless steel sheets. Medium-width belts are generally used on a backstand for weld removal or for removing casting gate.
