3M 7010309563 Trizact 337DC Abrasive Belt 132x2 Inch Ao

Product Description

The 3M 7010309563 is a Trizact 337DC coated abrasive belt designed for intermediate to final finishing in medium-pressure grinding and surface preparation applications. Built on a durable X-weight cloth backing, the belt uses aluminum oxide mineral with a grinding aid to reduce friction and manage heat during dry grinding. Macroreplicated abrasive structures contain multiple layers of mineral, allowing controlled breakdown that produces consistent, repeatable finishes across the full life of the belt. At 132 inches long and 2 inches wide, this belt fits standard wide-contact and stroke-sander configurations common in metal fabrication and finishing shops.

This belt is suited for metalworking environments where intermediate stock removal and finish refinement need to happen efficiently, sometimes in a single operation. The channel geometry of the abrasive structures helps clear swarf from the work surface, reducing loading and keeping the contact zone cleaner. It is commonly used by fabricators, weld finishers, and metal polishing professionals working on stainless steel, carbon steel, and similar ferrous and non-ferrous substrates. Minimum order quantity is 5 belts per purchase.

Key Features

• Macroreplicated abrasive bricks with multiple mineral layers deliver controlled breakdown and consistent finish results
• Channel geometry removes swarf and keeps the work surface cleaner during grinding
• X-weight cloth backing provides durability for medium-pressure applications
• Aluminum oxide mineral with grinding aid reduces friction and controls workpiece temperature in dry grinding
• Capable of combining stock removal and finishing into a single belt operation
• Extended belt life reduces per-part abrasive cost and simplifies inventory management

Compatibility

Designed for use on belt grinders and stroke sanders accepting a 132-inch by 2-inch abrasive belt. Suitable for metal fabrication, weld blending, and surface finishing applications on ferrous and non-ferrous workpieces.

Installation Notes

Belt installation should be performed by qualified personnel following the machine manufacturer's tracking and tensioning procedures. Confirm the sander or grinder is powered down and de-energized before changing belts. Inspect the contact wheel, platen, and drive components for wear before mounting a new belt. Always verify belt direction of travel matches the arrow or seam orientation marked on the belt before starting the machine.
