3M 7000120691 Scotch-brite Sc-bs Surface Conditioning Belt

Product Description

The 3M 7000120691 is a Scotch-Brite SC-BS surface conditioning belt designed for industrial and metalworking applications requiring consistent, controlled surface finishing. Built on a reinforced scrim backing with a nonwoven open-web construction and aluminum oxide (AO) abrasive bonded with resin, this belt measures 132 inches in length and 6 inches in width. It delivers repeatable results across blending, deburring, fine finishing, and brushed-finish work on metal surfaces. The open-web structure reduces loading and heat buildup, allowing extended run time without sacrificing surface quality. Licensed tradespeople and production metalworking shops are the primary users.

This belt is suited for detail work on a range of metals including stainless steel, carbon steel, and aluminum. Typical applications include blending weld lines, deburring edges, setting grain on flat stock, contour finishing on complex-shaped parts, and attaining straightline-brushed surface finishes. The conformable nonwoven construction keeps the abrasive in contact with irregular and curved workpiece geometry, making it well-suited for both manual operations and robotic processing cells. It is sold individually and is intended for use on standard belt grinders and finishing machines that accept 132-inch by 6-inch belts.

Key Features

• Nonwoven open-web construction reduces loading and heat buildup for extended operating time
• Aluminum oxide abrasive bonded with resin on a reinforced scrim backing for durability and flexibility
• Conformable structure maintains abrasive contact on contoured, curved, and complex-shaped parts
• Handles blending, deburring, fine finishing, grain setting, and straightline-brushed finishes on metal
• Removes surface imperfections including grind lines, mill marks, and other surface defects
• Suitable for both manual belt finishing and automated robotic processing applications

Compatibility

Designed for use on belt grinders and surface conditioning machines that accept a 132-inch by 6-inch belt format. Suitable for finishing operations on stainless steel, carbon steel, aluminum, and other common metals.

Installation Notes

Installation and belt changes should be performed by qualified personnel with the machine powered down and locked out per applicable OSHA lockout/tagout procedures. Verify that the belt grinder or finishing machine is rated for the belt dimensions before mounting. Inspect the belt for damage before each use and confirm proper tracking before resuming production. Follow the machine manufacturer guidelines for belt tension and guard clearance.
