3M 7000120757 Scotch-brite Surface Conditioning Belt

Product Description

The 3M 7000120757 is a Scotch-Brite Surface Conditioning Low Stretch Belt designed for blending, finishing, and light deburring across a range of metalworking and fabrication tasks. Built on a durable polyester scrim backing, it resists stretching during high-speed belt operations, helping maintain consistent contact with the workpiece. The open non-woven nylon web construction is load-resistant, shedding swarf and debris to extend abrasive service life. At 42 inches long and 1 inch wide, it fits standard narrow belt finishing equipment used in metal fab shops and maintenance settings. Aluminum oxide mineral with a resin bond delivers moderate cut and finish in one pass.

This belt is suited for surface conditioning work on stainless steel, brass, aluminum, and other metals in both production and maintenance environments. Its moderate aggressiveness makes it effective in multi-step sequences where operators need to blend welds, remove light oxidation, or prep surfaces without marring the substrate geometry. Fabricators, maintenance machinists, and metal finishing technicians are the primary installers and users. It ships in a minimum quantity of 10 belts per order.
