3M 7000120723 Abrasive Belt 4x24 in Aluminum Oxide Medium

Product Description

The 3M 7000120723 is a non-woven aluminum oxide abrasive belt designed for surface conditioning, blending, and finishing on metal and other materials. Part of the SC-BS series, it measures 4 inches wide by 24 inches long and carries a medium grade abrasive rating. The non-woven construction uses aluminum oxide abrasive bonded to a scrim backing, which allows consistent cut rate across the belt face while conforming to irregular surfaces. This belt supports both wet and dry operation, making it suitable for a range of shop and field conditions. Trade professionals handling deburring, weld blending, and surface prep will find this belt a practical fit for standard belt grinders and finishing machines.

This abrasive belt is used in metalworking, fabrication, HVAC ductwork prep, and light industrial finishing applications. The 4 x 24 inch format fits common bench-top and portable belt grinders used in plumbing, mechanical, and sheet metal trades. The medium grade is appropriate for intermediate surface conditioning work, removing light scale, oxidation, or weld discoloration before final surface treatment. Its wet and dry compatibility makes it usable in both dry shop grinding setups and wet finishing applications where fluid cooling or cleanup is needed.
