3M 7010299332 Trizact 337DC Abrasive Belt 132x2 Inch Ao

Product Description

The 3M 7010299332 is a Trizact 337DC aluminum oxide abrasive belt designed for intermediate to final finishing in medium-pressure grinding and blending applications. Built on a durable X-weight cloth backing, it measures 132 inches long and 2 inches wide. The belt uses a macroreplicated structure where abrasive bricks contain multiple layers of mineral, allowing controlled breakdown over the life of the belt. A built-in grinding aid reduces friction and keeps the workpiece cool during dry grinding. This belt is used by metalworkers, fabricators, and finishing technicians working on industrial belt grinders and wide-belt sanders.

The 337DC belt is suited for ferrous and non-ferrous metal finishing in production environments where consistent surface finish quality is required across multiple workpieces. Its cloth backing handles the demands of contoured and flat surface work. The structured abrasive design allows it to perform grinding and finishing in a single operation, reducing process steps on the shop floor. Fabrication shops, weld grinding operations, and precision metalworking facilities are typical use environments.

Key Features

• Macroreplicated abrasive bricks contain multiple mineral layers for controlled, consistent cut
• Channels between bricks evacuate swarf and keep work surfaces cleaner during use
• Controlled mineral breakdown produces predictable finishes over the full belt life
• Built-in grinding aid reduces friction and workpiece heat in dry grinding applications
• X-weight cloth backing withstands medium-pressure applications on both flat and contoured surfaces
• Capable of grinding and finishing in one operation, reducing abrasive changeovers

Compatibility

Designed for use on industrial belt grinders and wide-belt finishing machines that accept 132-inch by 2-inch abrasive belts. Verify machine belt-length and width capacity before installation.

Installation Notes

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