3M 7010307886 Abrasive Belt 15.5x3.5 Inch Aluminum Oxide

Product Description

The 3M 7010307886 is a Trizact cloth abrasive belt engineered for intermediate finishing and fine polishing applications. It uses a proprietary microreplication process in which micron-graded aluminum oxide particles are formed into uniform three-dimensional pyramids and bonded to a flexible rayon backing. As the pyramids wear during use, fresh, sharp mineral is continuously exposed, producing a consistent cut rate and a predictable fine finish from start to finish. The belt measures 15.5 inches in length and 3.5 inches in width. It is used by metal fabricators, finishing technicians, and industrial maintenance trades.

This belt is suited for intermediate stock removal and fine finishing on metal surfaces, including applications where parts will proceed to plating, buffing, or coating. The flexible rayon backing conforms to contoured and curved surfaces, making it effective for both flat and complex profiles. Its consistent cut and finish characteristics make it a reliable choice in robotic or automated finishing systems where repeatability is critical.

Key Features

• Microreplication technology forms aluminum oxide into precise pyramidal structures for controlled, consistent cutting action
• Self-sharpening pyramid design exposes fresh mineral as the abrasive wears, extending usable belt life
• Runs cooler than conventional abrasives, reducing heat-related surface distortion on sensitive workpieces
• Flexible rayon backing conforms to contoured surfaces for uniform finishing across complex geometries
• Three-dimensional abrasive structure delivers repeatable finishes in robotic and automated applications
• Produces finer surface finishes than conventional electrostatically coated abrasive belts

Compatibility

Designed for use on belt finishing machines and grinders that accept a 15.5-inch by 3.5-inch abrasive belt. Suitable for metal finishing operations including pre-plate, pre-buff, and fine polishing stages.

Installation Notes

Installation should be performed by qualified finishing or maintenance personnel familiar with abrasive belt equipment. Power down and lock out the machine before changing belts. Confirm belt tracking and tension per the equipment manufacturer's guidelines before resuming operation. Inspect the contact wheel and platen for wear that could affect belt performance or cause premature belt failure.
