3M 7010359670 Microfinishing Film Belt 372L 72x2 Inch Ao

Product Description

The 3M 7010359670 is a microfinishing film belt designed for precision surface finishing across a range of materials including metal, composites, fiberglass, and plastic. The belt uses micron-graded aluminum oxide abrasive bonded to a polyester film backing, delivering a fast cut rate alongside a consistent, uniform finish. Resin bonding holds the abrasive firmly in place and resists heat-related deterioration, extending service life during high-cycle grinding and finishing operations. The closed-coat construction maintains high grain density for repeatable results. This belt is sized at 72 inches long by 2 inches wide and is intended for use by machinists, metal fabricators, and finishing technicians working with belt grinding or polishing equipment.

The 372L belt is well suited for fine finishing applications in both shop and production environments. It performs on composites, plastics, fiberglass, and metal substrates where a uniform, fine surface finish is required. The polyester film backing provides consistent flexibility, making it effective on flat and contoured surfaces. It is commonly used in aerospace, automotive, and general metalworking finishing operations where surface finish quality is critical and repeatable stock removal is needed at the final stages of the process.

Key Features

• Micron-graded aluminum oxide abrasive for fast cutting and fine, consistent surface finish
• Durable polyester film backing offers flexibility for uniform contact on finished surfaces
• Resin bonding resists heat deterioration, extending abrasive belt service life
• Closed-coat construction delivers high grain density for finer finishing results
• Coated abrasive construction suited for composites, plastics, fiberglass, and metal

Compatibility

Designed as a replacement or production abrasive belt for belt grinders and finishing machines that accept a 72-inch by 2-inch belt configuration.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician familiar with belt grinder operation. Power down and lock out the machine before changing belts. Verify belt tracking and tension per the equipment manufacturer guidelines before resuming operation. Inspect the belt for damage or defects prior to each use and do not exceed the equipment's rated belt speed.
