3M 7100109886 Trizact 337DC Abrasive Belt 72x2 Inch Ao

Product Description

The 3M 7100109886 is a Trizact 337DC abrasive belt designed for intermediate to final finish applications under medium pressure. Built on a durable X-weight cloth backing, it uses aluminum oxide mineral combined with a grinding aid to reduce friction and keep the workpiece cool during dry grinding. The macroreplicated abrasive structure delivers controlled, consistent cutting action across the full life of the belt. Licensed HVAC, metalworking, and fabrication trades rely on this belt for grinding and finishing ferrous and non-ferrous workpieces in a single operation.

This belt is suited for surface finishing work in metal fabrication shops, maintenance facilities, and industrial production environments. The 72-inch length and 2-inch width fit wide-belt and stroke sanders configured for long-form finishing passes. It performs well on stainless steel, aluminum, and carbon steel where a consistent, predictable surface finish is required across multiple workpieces.

Key Features

• Macroreplicated abrasive bricks contain multiple layers of aluminum oxide mineral for controlled, even breakdown
• Channeled structure evacuates swarf from the work surface, reducing loading and keeping surfaces cleaner
• Grinding aid minimizes friction and limits heat buildup during dry grinding operations
• X-weight cloth backing provides durability for medium-pressure applications
• Extended belt life lowers abrasive cost per part and reduces inventory turnover
• Capable of grinding and finishing in a single operation, reducing process steps

Compatibility

Designed as a replacement-style abrasive belt for wide-belt and stroke sanding machines configured to accept 72-inch length by 2-inch width belts with a cloth backing.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt equipment. Power down and lock out the machine before changing belts. Verify belt tracking and tension settings per the machine manufacturer guidelines before resuming operation. Inspect the belt for tears or edge damage before each use.
