3M 7100210339 Cubitron Ii 966F Belt 36 Grit 126x42 Inch

Product Description

The 3M 7100210339 is a Cubitron II 966F ceramic abrasive cloth belt built for aggressive stock removal and surface finishing on demanding metal substrates. Precision shaped ceramic grain sits on a Y-weight polyester cloth backing that resists water, making this belt suitable for both wet and dry grinding applications. The resin bond system manages heat during cutting, which helps prevent discoloration of workpiece surfaces. At 126 inches long and 42 inches wide, this belt is sized for large-footprint wide-belt sanders and finishing machines common in fabrication environments.

This belt is engineered for metalworking applications involving stainless steel, titanium, and high-nickel alloys — materials that are sensitive to heat and prone to surface discoloration under conventional abrasives. The 36-grit designation places it in the aggressive cutting range, making it well-suited to weld blending, heavy stock removal, and rough surface conditioning on flat or wide-format workpieces. It is typically used by metal fabricators, surface finishing shops, and industrial grinding operations that require consistent cut rate over extended run times.

Key Features

• Precision shaped ceramic grain delivers high cut rate and extended belt life
• Y-weight polyester cloth backing provides toughness and flexibility under aggressive sanding loads
• Water-resistant backing allows use with liquid lubricants in wet applications
• Resin bond resists heat buildup to minimize workpiece discoloration
• Effective on stainless steel, titanium, and high-nickel alloys
• 36 grit for aggressive stock removal and weld blending

Compatibility

Designed for use on wide-belt grinding and finishing machines that accept belts measuring 126 inches in length and 42 inches in width. Suitable for wet or dry metalworking applications.

Installation Notes

Belt installation should be performed by qualified machine operators following the equipment manufacturer's belt-tracking and tension procedures. Power down and de-energize the machine fully before mounting or removing the belt. Verify belt direction-of-travel arrows align with machine rotation before startup. Inspect the platen and contact drum for wear or damage that could cause uneven belt loading.
