3M 7100109897 Abrasive Belt 72x2 Inch Aluminum Oxide

Product Description

The 3M 7100109897 is a Trizact 337DC coated abrasive belt designed for intermediate to final finishing in medium-pressure grinding applications. Built on a durable X-weight cloth backing, it uses aluminum oxide mineral combined with a grinding aid to reduce friction and keep workpieces cool during dry grinding. The macroreplicated abrasive structure — sometimes called bricks — contains multiple layers of mineral with channeled gaps that clear swarf and maintain a cleaner work surface. This belt is suited for metal fabrication environments where consistent, repeatable surface finishes are required across the full life of the belt.

This belt is sized at 72 inches in length and 2 inches in width, making it compatible with standard belt grinders and wide-belt finishing machines used in metalworking shops. It is well suited for applications requiring a single-pass operation that combines grinding and finishing, reducing the need for multiple abrasive steps. Licensed tradespeople and production grinding technicians working on ferrous and non-ferrous metals are the primary installers and operators of this product.

Key Features

• Macroreplicated abrasive bricks contain multiple mineral layers for extended cut life
• Channeled surface clears swarf and keeps work surfaces cleaner during operation
• Controlled mineral breakdown produces consistent, predictable finishes over belt life
• Grinding aid reduces friction and heat buildup for dry grinding applications
• X-weight cloth backing provides durability for medium-pressure applications
• Capable of grinding and finishing in a single operation, reducing abrasive steps

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive belt for standard belt grinders and finishing machines that accept a 72-inch by 2-inch belt in intermediate to final finish applications.

Installation Notes

Installation should be performed by qualified grinding equipment operators following the machine manufacturer's guidelines for belt tensioning and tracking. Power down and lockout the grinder before mounting or removing the belt. Inspect the contact wheel and platen for wear before installing a new belt to avoid premature belt failure. Always confirm belt direction of travel is consistent with the arrow marked on the belt, if present.
