3M 7000120321 Trizact Cloth Belt 4x90 in A100 Grit

Product Description

The 3M 7000120321 is an aluminum oxide Trizact cloth abrasive belt designed for consistent, controlled material removal in grinding and finishing applications. Built on an X-weight full-flex cloth backing with resin bonding, it delivers reliable heat resistance across extended use cycles. The A100 grit rating positions this belt for fine grinding and surface refinement. A built-in grinding aid promotes cooler cutting, reducing heat buildup at the workpiece surface. The film media splice construction supports smooth, uninterrupted belt travel. This belt is used by metalworking fabricators, weld finishing crews, and industrial maintenance trades working with angle grinders, belt grinders, and similar abrasive equipment.

This belt measures 4 inches wide by 90 inches long, making it compatible with standard 4 x 90 inch belt grinder machines used in industrial and fabrication shop environments. The Trizact structured abrasive technology uses a pyramid-shaped mineral matrix that wears down gradually, exposing fresh cutting edges over the life of the belt. This characteristic makes it well-suited for applications where consistent surface finish quality is required over multiple passes, including weld blending, deburring, and fine stock removal on metal workpieces.

Key Features

• Aluminum oxide Trizact structured abrasive for consistent, long-lasting cut performance
• A100 grit rating suited for fine grinding and surface finishing work
• X-weight full-flex cloth backing provides durability and conformability on contoured surfaces
• Resin bond construction resists heat buildup during aggressive grinding cycles
• Grinding aid additive promotes cooler cutting to protect workpiece integrity
• Film media splice for smooth, consistent belt travel without interruption at the joint

Compatibility

Designed for use on belt grinder machines that accept 4 inch by 90 inch abrasive belts in industrial metalworking and fabrication applications.

Installation Notes

Belt installation should be performed by trained personnel following machine manufacturer guidelines. Verify belt grinder is fully powered down and locked out before mounting or removing belts. Confirm belt tracking and tension settings before resuming operation. Always wear appropriate PPE including eye protection and gloves when handling abrasive belts and operating grinding equipment.
