3M 7100179659 Trizact 337DC Abrasive Belt 15.5x3.5 Inch Ao

Product Description

The 3M 7100179659 is a Trizact 337DC aluminum oxide abrasive belt built for intermediate to final finish work in medium-pressure grinding and finishing applications. The belt uses a macroreplicated structure where abrasive minerals are formed into layered bricks with channels between them to evacuate swarf and keep the work surface cleaner during operation. The X-weight cloth backing provides durability under load, and a grinding aid is incorporated to reduce friction and manage workpiece heat during dry grinding. This belt measures 15.5 inches in length and 3.5 inches in width and is sold individually.

This belt is suited for metalworking environments where consistent, repeatable surface finishes are required across a production run. The controlled mineral breakdown mechanism delivers predictable finish results from the start of the belt's life through to the end, reducing process variability. It is commonly used in fabrication shops, aerospace component finishing, and general metal finishing operations where both grinding and finishing steps need to be consolidated into a single pass. Installers and operators in industrial grinding environments are the primary users of this product.

Key Features

• Macroreplicated abrasive bricks contain multiple mineral layers for consistent cut and finish
• Channels between abrasive bricks evacuate swarf and reduce loading on the work surface
• Controlled mineral breakdown provides predictable finish results over the full belt life
• X-weight cloth backing withstands medium-pressure applications without premature failure
• Integrated grinding aid reduces friction and keeps workpieces cooler during dry grinding
• Capable of combining grinding and finishing into a single belt operation

Compatibility

Designed as a replacement-style abrasive belt for use on belt grinding machines and finishing equipment that accept 15.5 inch by 3.5 inch belts. The Trizact 337DC series is available in widths from 0.5 to 24 inches and grades from A300 to A30 for varied finishing requirements.

Installation Notes

Installation should be performed by qualified machine operators following the equipment manufacturer's belt-change procedure. Confirm the machine is powered down and any pneumatic or hydraulic tension systems are fully released before removing or installing the belt. Ensure belt tracking is adjusted according to the grinder manufacturer's specifications before resuming operation. Always verify belt direction arrows align with the drive direction of the machine.
