3M 7010308284 Trizact 337DC Abrasive Belt 18x3/4 Inch

Product Description

The 3M 7010308284 is a Trizact 337DC abrasive belt designed for intermediate to final finishing in medium-pressure grinding and polishing applications. Built on a durable X-weight cloth backing, it uses aluminum oxide mineral with a grinding aid to reduce friction and keep workpieces cool during dry grinding. The macroreplicated abrasive structure consists of precision-shaped bricks containing multiple layers of mineral, with channels that clear swarf and maintain a cleaner work surface. This belt measures 18 inches in length and 3/4 inch in width. Metal fabricators, weld finishers, and precision grinding shops are the primary users.

This belt is suited for medium-pressure finish grinding on metal workpieces where consistent surface finish is critical. The controlled mineral breakdown delivers predictable, repeatable results across the full life of the belt, making it appropriate for production environments where finish uniformity matters. It is available in widths from 1/2 inch to 24 inches and in grades from A300 to A30, allowing selection across a range of finishing stages.

Key Features

• Macroreplicated abrasive bricks with multiple mineral layers for controlled, consistent cut
• Channels between bricks remove swarf and keep the work surface cleaner during grinding
• Grinding aid reduces friction and controls heat for dry grinding applications
• X-weight cloth backing provides durability for medium-pressure operations
• Capable of grinding and finishing in a single operation, reducing process steps
• Extended belt life reduces per-part abrasive cost and simplifies inventory management

Compatibility

Designed as a replacement-style abrasive belt for standard belt grinding and finishing machines accepting 18 inch by 3/4 inch belts. Available in grades from A300 to A30 and widths from 1/2 inch to 24 inches to fit a range of equipment configurations.

Installation Notes

Installation should be performed by a qualified operator following the machine manufacturer's belt tensioning and tracking guidelines. Ensure the grinder is powered down and locked out before changing the belt. Verify belt direction-of-travel arrow aligns with the machine's drive direction before startup. Inspect the platen and contact wheel for wear before installing a new belt.
