3M 7010328666 Abrasive Belt 132x3 Inch Aluminum Oxide

Product Description

The 3M 7010328666 is a Trizact 307EA coated abrasive belt engineered for intermediate finishing and fine polishing applications. It uses microreplication technology in which micron-graded aluminum oxide particles are formed into precise three-dimensional pyramids and bonded to a flexible rayon cloth backing. As the pyramids wear during use, fresh sharp mineral is continuously exposed, delivering a consistent cut rate and predictable finish quality from start to finish. At 132 inches long and 3 inches wide, this belt is suited for wide-belt and stroke-belt machines common in metal fabrication and surface preparation work. Fabricators, finishing technicians, and industrial maintenance professionals install and use this product.

This belt is designed for intermediate finishing and fine polishing prior to plating or buffing operations. The flexible rayon backing conforms to contoured and irregular surfaces, making it practical for parts that are not perfectly flat. The three-dimensional abrasive structure produces very consistent surface finishes throughout the life of the belt, which is particularly valuable in automated and robotic finishing lines where repeatability is critical. It is also well suited for manual stroke-belt finishing on metal workpieces requiring controlled scratch patterns.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening pyramids for consistent cut and finish
• Fresh mineral is continuously exposed as pyramids wear, extending usable belt life
• Runs cooler than conventional abrasives, reducing heat buildup on workpiece surfaces
• Flexible rayon cloth backing conforms to contoured surfaces for uniform contact
• Three-dimensional abrasive design delivers repeatable finishes in robotic and automated applications
• Produces finer finishes than conventional electrostatically coated abrasive belts

Compatibility

Designed for use on wide-belt finishing machines and stroke-belt sanders that accept a 132-inch by 3-inch abrasive belt. Suitable for metal fabrication, pre-plate finishing, and polishing operations on ferrous and non-ferrous workpieces.

Installation Notes

Installation should be performed by a qualified finishing technician or machine operator familiar with belt-tensioning and tracking procedures for the specific machine in use. Verify the machine is fully de-energized and any pneumatic tension systems are relieved before changing the belt. Confirm correct belt tracking direction, as most coated abrasive belts are directional; check the arrow printed on the inner surface of the belt. Inspect the platen, contact drum, and idler rollers for wear or debris before mounting a new belt.
