3M 7010329209 Abrasive Belt 1x21 in Aluminum Oxide Medium

Product Description

The 3M 7010329209 is a non-woven aluminum oxide abrasive belt designed for surface finishing, blending, and light deburring across metal, wood, and composite substrates. Measuring 1 inch wide by 21 inches long, it fits standard 1x21 belt sanders and similar portable finishing tools. The medium grade abrasive provides a balance between material removal and surface refinement, making it well suited for intermediate finishing passes. The polyester cloth backing offers flexibility and durability under both wet and dry operating conditions, extending belt life in demanding shop environments. Licensed tradespeople in HVAC, plumbing, fabrication, and general maintenance use this belt for pipe prep, weld blending, and surface conditioning tasks.

This belt is appropriate for use in light industrial, maintenance, and trade service applications where a controlled scratch pattern and consistent finish are required. The SC-BL series non-woven construction conforms to irregular surfaces better than coated abrasive belts, making it useful for contoured workpieces and pipe fittings. It supports both wet and dry operation, giving the user flexibility depending on the material and cooling requirements of the application. Sold as a single belt per package.
