3M 7100109885 Trizact 337DC Abrasive Belt 72x2 Inch Ao

Product Description

The 3M 7100109885 is a Trizact 337DC abrasive belt built for intermediate to final finishing on metal and other hard surfaces. It uses aluminum oxide mineral on a durable X-weight cloth backing with a grinding aid that reduces friction and keeps the workpiece cool during dry grinding operations. The macroreplicated abrasive structure features layered mineral bricks separated by channels that clear swarf and leave the work surface cleaner between passes. The belt measures 72 inches in length and 2 inches in width. It is suited to medium-pressure applications where consistent, controlled material removal is required.

This belt is used in metal fabrication and finishing environments where operators need to grind and finish in a single operation. The controlled mineral breakdown provides predictable surface finishes across the full life of the belt, reducing the variability that comes from uneven abrasive wear. Typical applications include weld blending, deburring, and surface conditioning on ferrous and non-ferrous metals. It is used on standard belt grinders and backstand finishing machines in industrial and job-shop settings. The extended belt life lowers per-piece abrasive cost and reduces how often belts need to be swapped out mid-job.

Key Features

• Macroreplicated abrasive bricks with multiple layers of aluminum oxide mineral for consistent cut rate
• Channels between abrasive structures clear swarf and keep the work surface cleaner
• Grinding aid reduces friction and workpiece heat during dry grinding
• X-weight cloth backing provides durability under medium-pressure applications
• Capable of grinding and finishing in a single operation, reducing process steps
• Extended belt life reduces abrasive spend and inventory turnover

Compatibility

Designed for use on standard belt grinders and backstand finishing machines that accept 2-inch wide by 72-inch long abrasive belts.

Installation Notes

Belt installation and replacement should be performed by qualified operators following machine manufacturer guidelines. Ensure the belt grinder or backstand is fully powered down and locked out before changing belts. Verify belt tracking adjustment after installation before resuming grinding operations. Confirm belt direction of travel matches the arrow marked on the belt, if present.
