3M 7100191982 Trizact 337DC Abrasive Belt 18x3/4 Inch Ao

Product Description

The 3M 7100191982 is a Trizact 337DC aluminum oxide abrasive belt built on an X-weight cloth backing for intermediate to final finish applications under medium pressure. The belt uses a macroreplicated structure where abrasive bricks contain multiple layers of mineral separated by channels. Those channels continuously clear swarf from the work surface, while controlled mineral breakdown produces consistent finishes from start to finish. A built-in grinding aid reduces friction and keeps the workpiece cool during dry grinding, making this belt appropriate for production finishing in metalworking and fabrication environments. Licensed trades and skilled fabricators install and use this product.

This belt is suited for intermediate and final finishing operations on metal workpieces in both shop and production settings. The combination of aluminum oxide mineral and cloth backing allows the belt to handle grinding and finishing in a single operation in many applications, reducing process steps. It is available across a wide range of widths from 1/2 inch to 24 inches and grades from A300 to A30, covering coarse stock removal through fine finishing work.

Key Features

• Macroreplicated abrasive bricks with built-in channels continuously remove swarf and keep work surfaces cleaner
• Controlled mineral breakdown delivers consistent, predictable finishes across the full belt life
• X-weight cloth backing provides durability for medium-pressure applications
• Grinding aid reduces friction and workpiece heat in dry grinding applications
• Capable of grinding and finishing in a single operation, reducing abrasive changeovers
• Extended belt life lowers per-part abrasive cost

Compatibility

Designed for use on belt grinders and finishing machines accepting 18-inch length by 3/4-inch width abrasive belts in metalworking and fabrication applications.

Installation Notes

Install on a belt grinder or similar abrasive finishing machine rated for the belt dimensions. Confirm the machine is fully powered down and locked out before changing belts. Verify belt tracking and tension according to the machine manufacturer guidelines before resuming operation. Always wear appropriate eye and hand protection during belt changes and grinding operations.
