High Quality Construction

3M Cloth 991FZ is specifically designed for woodworking and sanding applications. Its durable construction and fast cutting abrasive material make it ideal for these tasks. The polyester cloth backing ensures smooth operation and long-lasting durability, allowing for consistent finishing. The abrasive side of the belt features a closed coat of grains and an anti-static treatment, preventing debris from loading on the belt.

Precision Shaped Grains

This belt utilizes revolutionary precision shaped ceramic grain technology. Unlike traditional abrasives that gouge or plow through hard surfaces, the precision shaped grains of 3M Cloth 991FZ slice cleanly. This results in a super-fast cut and reduces heat build-up in the workpiece. The abrasive itself stays cooler and sharper, leading to significantly longer belt life compared to conventional ceramic grain belts. This not only decreases costs but also reduces the frequency of belt changeovers.

The Cubitron II Advantage

3M Cubitron II products have set a new standard for high-performing abrasives. The engineers at 3M started with their Ceramic Precision Shaped Abrasive Grain and used advanced technology to electrostatically orient each triangular structure on the backing. This unique arrangement forms sharp peaks that maximize cutting potential. These peaks act like individual cutting tools, efficiently slicing through wood and ensuring extended high performance in heavy-duty production applications. The grains wear evenly, providing extra-long life and consistency with less grinding pressure. As a result, Cubitron II products maximize productivity and minimize belt stress.
