3M 7100089709 Trizact 337DC Abrasive Belt 24x0.5 in Ao

Product Description

The 3M 7100089709 is a Trizact 337DC abrasive belt built for intermediate to final finish applications under medium pressure. It uses aluminum oxide mineral on a durable X-weight cloth backing with a grinding aid that reduces friction and keeps workpieces cool during dry grinding. The macroreplicated abrasive structure features layered mineral bricks separated by channels that clear swarf from the work surface. The result is a more consistent, predictable finish from start to finish of the belt's service life. Licensed tradespeople and metalworking shops use this belt where controlled cut and finish quality matter.

This belt is suited for metal finishing operations requiring a single abrasive step that handles both grinding and finishing. The 24-inch length and 1/2-inch width fit narrow-contact and file-belt configurations common in fabrication, tool-and-die, and general metalworking environments. The grinding aid coating makes it especially practical for dry applications where workpiece temperature control is a priority.

Key Features

• Macroreplicated abrasive bricks contain multiple layers of aluminum oxide mineral for extended cut life
• Channels between abrasive bricks clear swarf and keep work surfaces cleaner throughout the cut
• Controlled mineral breakdown produces consistent, predictable finishes over the belt's full service life
• Grinding aid reduces friction and limits heat buildup during dry grinding operations
• X-weight cloth backing handles medium-pressure applications without backing failure
• Capable of combining grinding and finishing into a single operation, reducing abrasive changeovers

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive belt for narrow-contact belt grinders and file-belt machines accepting a 24-inch length by 1/2-inch width configuration.

Installation Notes

Installation should be performed by a qualified operator following the machine manufacturer's belt-tensioning and tracking procedures. Power down and de-energize the grinder completely before removing the worn belt or mounting a new one. Verify belt orientation and tracking before resuming operation. Wear appropriate PPE including eye protection and gloves during belt changes.
