3M 7100089193 Trizact 337DC Abrasive Belt 18x0.5 in Ao

Product Description

The 3M 7100089193 is a Trizact 337DC abrasive belt designed for intermediate to final finish applications under medium pressure. Built on a durable X-weight cloth backing with aluminum oxide mineral and a grinding aid, this belt uses macroreplicated abrasive bricks that contain multiple layers of cutting mineral. Channels between the bricks continuously clear swarf from the work surface, keeping contact zones cleaner and cooler during dry grinding. The belt measures 18 inches in length and 1/2 inch in width. It is suited for metal fabrication, finishing shops, and precision grinding operations where consistent, repeatable surface finish is required.

This belt is used in production and job-shop environments for metal grinding and finishing on narrow contact wheel or platen setups. Its X-weight cloth backing handles moderate to firm pressure without degrading prematurely. The grinding aid reduces friction and heat buildup, making it effective for dry grinding passes where workpiece temperature control matters. The 1/2-inch width suits narrow belt grinders, die grinder attachments, and file-belt machines common in fabrication and toolroom settings.

Key Features

• Macroreplicated abrasive bricks with multiple mineral layers for consistent cut throughout belt life
• Channeled structure removes swarf continuously and keeps work surfaces cleaner
• Controlled mineral breakdown produces predictable, repeatable surface finishes
• Grinding aid reduces friction and heat for effective dry grinding
• X-weight cloth backing withstands medium-pressure grinding and finishing in a single operation
• Extended belt life reduces per-part abrasive cost and lowers inventory requirements

Compatibility

Designed as an OEM-style replacement or direct-use abrasive belt for narrow belt grinders, file-belt machines, and contact wheel setups accepting 18-inch by 1/2-inch abrasive belts.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive belt equipment. Power down and lock out the grinder before mounting or removing any belt. Confirm belt tracking and tension per the machine manufacturer guidelines before resuming operation. Inspect the belt for cuts or separation before each use and replace immediately if damage is found.
