3M 7100089192 Trizact 337DC Abrasive Belt 18x0.5 in

Product Description

The 3M 7100089192 is a Trizact 337DC coated abrasive belt designed for intermediate to final finish applications under medium pressure. Built on a durable X-weight cloth backing, this belt uses aluminum oxide mineral combined with a grinding aid to reduce friction and keep the workpiece cool during dry grinding. The macroreplicated abrasive structure organizes the mineral into layered bricks with channels between them, which evacuate swarf and help maintain a cleaner work surface throughout the cut. Licensed abrasive fabricators and metal finishing shops rely on this belt for consistent, repeatable surface finishes.

This belt is suited for precision grinding and finishing on metal workpieces in fabrication, aerospace, and general manufacturing environments. The 18-inch length and 1/2-inch width fit narrow-contact and file-belt configurations common in tool and die work, weld blending, and contour finishing. The grinding aid makes it effective for dry applications where heat buildup is a concern. The controlled mineral breakdown extends belt life beyond conventional coated abrasives, allowing operators to grind and finish in a single operation in many cases.

Key Features

• Macroreplicated abrasive bricks contain multiple layers of aluminum oxide mineral for consistent cut and finish
• Channels between abrasive bricks evacuate swarf and keep the work surface cleaner during grinding
• Grinding aid reduces friction and limits heat transfer to the workpiece in dry grinding applications
• Controlled mineral breakdown delivers predictable, repeatable finishes over the full belt life
• X-weight cloth backing provides durability for medium-pressure applications
• Capable of combining grinding and finishing into a single operation, reducing process steps

Compatibility

Designed for use on narrow file-belt machines and contact-wheel grinders that accept 18-inch length by 1/2-inch width abrasive belts. Suitable for dry grinding and finishing of metal workpieces in medium-pressure applications.

Installation Notes

Install abrasive belts only on properly guarded belt grinders rated for the belt dimensions and operating speed. Verify belt tracking and tension before powering on the machine. Inspect the belt for tears or separation at the splice before each use and replace immediately if damage is found. Follow the equipment manufacturer and applicable ANSI abrasive safety standards when mounting or changing belts.
