3M 7000120720 Scotch-brite Surface Conditioning Belt

Product Description

The 3M 7000120720 is a Scotch-Brite surface conditioning belt designed for metalworking applications where consistent finish quality and part integrity matter. Built on a reinforced nonwoven open-web construction with an aluminum oxide abrasive and resin bond over a scrim backing, this belt measures 132 inches in length and 3 inches in width. It handles a wide range of detail operations including blending, deburring, contour finishing, and producing straightline-brushed finishes. Technicians and finishing operators working on production lines or at the bench rely on this belt when surface quality and repeatable results are required.

This belt is suited for metal finishing work across residential fabrication shops, commercial production environments, and automated robotic processing cells. Typical applications include blending weld lines and grind marks, deburring edges, cleaning surfaces, setting the grain, and achieving fine or flat finishes on stainless steel and other metals. The nonwoven structure conforms well to complex part geometries, making it practical for contoured and irregular workpiece profiles encountered in general metalworking and light manufacturing.

Key Features

• Nonwoven open-web construction reduces loading and heat build-up for extended operating life
• Aluminum oxide abrasive with resin bond delivers consistent surface conditioning performance
• Reinforced scrim backing provides flexibility for detail work over contours and edges
• Conformable structure maintains abrasive contact on complex-shaped parts in robotic processing
• Removes surface imperfections, grind lines, mill marks, and other surface defects
• Suitable for blending, deburring, cleaning, contour finishing, and straightline-brushed finishes

Compatibility

Designed as a replacement or production-run belt for bench-mounted and machine belt finishing equipment that accepts a 132-inch by 3-inch belt configuration.

Installation Notes

Belt installation should be performed by the equipment operator following the belt grinder or finishing machine manufacturer's guidelines. Disconnect and lock out power to the machine before changing belts. Verify belt tracking and tension before resuming operation. Follow applicable shop safety procedures including eye and respiratory protection when operating surface conditioning equipment.
