3M 7100160702 Cubitron Ii 966F Belt 50 Grit 138x4 Inch

Product Description

The 3M 7100160702 is a coated abrasive belt built on the Cubitron II 966F platform, designed for aggressive surface finishing on metals. It uses precision shaped ceramic grain bonded to a Y-weight polyester cloth backing. The ceramic grain fractures along controlled edges as it wears, maintaining a sharp cutting surface throughout the belt's life. At 50 grit, it removes material quickly while leaving a consistent finish. Resin bonding resists heat buildup, which reduces the risk of heat discoloration on sensitive alloys. The belt measures 138 inches long by 4 inches wide and weighs 1.51 pounds.

This belt is suited for grinding, blending, and finishing operations on stainless steel, titanium, and high-nickel alloys in fabrication, welding, and metalworking applications. The water-resistant polyester backing allows use with liquid coolants or lubricants, making it viable for both wet and dry grinding setups. It is commonly run on stationary or portable belt grinders in industrial shops, aerospace fabrication, and food-grade equipment manufacturing where discoloration-free finishes are required.
