3M 7000028166 Trizact Cloth Belt A80 3.5x15.5 in

Product Description

The 3M 7000028166 is an aluminum oxide Trizact abrasive belt designed for precision grinding and finishing applications across metalworking and fabrication trades. Built on an X-weight cloth backing, it delivers the rigidity and durability required for aggressive stock removal while maintaining consistent cut performance over the belt's service life. Resin bonding provides heat resistance during extended grinding cycles, and an integrated grinding aid promotes cooler operation to reduce workpiece discoloration and extend abrasive life. The A80 grit designation targets medium material removal and surface conditioning tasks. A film media splice construction supports smooth, uninterrupted passes across the workpiece.

This belt is suited for use on stationary belt grinders and portable abrasive belt tools in metal fabrication shops, weld-prep operations, and finishing lines. The 3.5-inch by 15.5-inch format fits a range of compact belt grinder configurations commonly used for contour grinding, weld blending, and part deburring. The X-weight backing handles the mechanical stress of production grinding on steel, stainless, and nonferrous alloys. Fabricators, toolmakers, and maintenance machinists are the primary users of this belt size and grit combination.

Key Features

• Aluminum oxide Trizact abrasive construction for consistent, controlled cut rate
• X-weight cloth backing provides durability under high-tension grinding conditions
• Resin bond system resists heat buildup during prolonged use
• Grinding aid additive promotes cooler grinding and reduces workpiece heat damage
• Film media splice for smooth belt tracking and uninterrupted surface contact
• A80 grit for medium stock removal and surface conditioning

Compatibility

Designed for belt grinders and abrasive finishing machines that accept a 3.5-inch by 15.5-inch belt. Verify platen and contact wheel dimensions on the host machine before installation.

Installation Notes

Belt installation should be performed with the grinder powered off and unplugged. Confirm correct belt tracking direction before starting the machine, as most abrasive belts are directional. Inspect the contact wheel and platen for wear or damage prior to mounting a new belt. Allow the belt to run unloaded for a brief period to confirm stable tracking before applying workpiece pressure.
