PRODUCT FAQ

What materials can the 3M™ Cubitron™ II Cloth Belt 966F be used on?

Great question! The 966F belt is designed for grinding and finishing a variety of metals, including stainless steel, carbon steel, and exotic alloys. Its versatility makes it ideal for many industrial applications.
What does "80+ YF-weight" mean on this abrasive belt?

That’s an important detail! "80+" refers to the grit size, which provides aggressive material removal with a finer finish than coarser grits. "YF-weight" means the backing is a heavy-duty polyester cloth—very strong and durable!
Is this belt water-resistant or suitable for wet grinding?

Absolutely—you’re all set! The polyester backing gives excellent tear resistance and also allows you to use it for both dry and moderate wet applications.
How does Sine-lok work on this abrasive belt?

I’m glad you asked! Sine-lok is a special joint construction that reduces vibration by creating a smooth splice, helping the belt run quietly and last longer during use.
What are some benefits of using Cubitron™ II abrasives over conventional belts?

You’ll love the upgrade! Cubitron™ II belts feature precision-shaped ceramic grain that cuts faster, lasts longer, runs cooler, and delivers consistent performance throughout their life—helping boost productivity while saving time and effort.

Tough, Durable, and Heat Resistant

The 3M™ Cubitron™ II Cloth Belt 966F is engineered to deliver exceptional performance in moderate pressure applications, thanks to its advanced abrasive technology. This belt features a robust Z & Y-weight polyester backing that provides outstanding strength and durability, making it suitable for both wet and dry sanding operations. Its water-resistant construction allows for use with liquid-based lubricants, ensuring reliable performance even in demanding environments. These qualities make the 966F cloth belt an excellent choice for projects that require a tough, long-lasting abrasive solution capable of withstanding rigorous use.

The Science of 3M Precision Shaped Grain

At the heart of the 3M Cubitron II Cloth Belt 966F is the innovative Precision Shaped Grain (PSG) technology, representing a significant leap forward in abrasive science. Developed through a proprietary process, the ceramic mineral grains are engineered to maximize both toughness and hardness. What sets PSG apart is its unique triangular shape, which is meticulously designed to continually fracture and expose fresh, razor-sharp cutting edges. Unlike traditional abrasives that tend to plow through material, PSG grains slice cleanly through substrates, resulting in a faster cut and reduced heat generation. This minimizes the risk of heat-related issues such as stress cracks and discoloration on the workpiece. Additionally, the cooler, sharper cutting action of PSG extends the belt’s lifespan, providing superior value and performance compared to conventional abrasives.

Get the Belt You Need

3M offers a comprehensive range of abrasive belts in various widths and lengths to accommodate a wide array of metalworking applications and belt sanding tools.
