3M 7100192699 Trizact 337DC Abrasive Belt 90x2 Inch Ao

Product Description

The 3M 7100192699 is a Trizact 337DC aluminum oxide abrasive belt built for intermediate to final finish work in medium-pressure grinding and finishing applications. It uses a macroreplicated structure where abrasive bricks contain multiple layers of mineral, allowing controlled breakdown over the belt life for consistent, predictable surface finishes. The X-weight cloth backing provides durability under sustained load, and a built-in grinding aid reduces friction to keep workpieces cooler during dry grinding. This belt measures 90 inches in length and 2 inches in width and is sold individually.

This belt is suited for metalworking operations where a single abrasive tool needs to handle both grinding and finishing in one pass. Typical applications include weld blending, deburring, and surface conditioning on ferrous and non-ferrous metals. The channel geometry built into the abrasive structure evacuates swarf continuously, keeping the contact zone cleaner and reducing loading. It is commonly used in fabrication shops, maintenance environments, and production grinding setups where consistent finish quality across multiple passes is required.

Key Features

• Macroreplicated abrasive bricks with multiple mineral layers deliver controlled, consistent breakdown
• Channel geometry removes swarf and keeps work surfaces cleaner during operation
• Grinding aid reduces friction and heat buildup for dry grinding applications
• X-weight cloth backing withstands medium-pressure applications and extended use
• Capable of grinding and finishing in a single operation, reducing process steps
• Extended belt life lowers per-part abrasive cost compared to conventional coated belts

Compatibility

Designed as an OEM-style replacement or direct-use abrasive belt for stationary belt grinders and finishing machines accepting a 90-inch by 2-inch belt configuration.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt equipment. Power down and lock out the machine before mounting or removing the belt. Confirm belt tracking and tension per the machine manufacturer guidelines before resuming operation. Inspect the belt for nicks, tears, or edge damage before each use and do not exceed the rated operating speed marked on the grinder.
