3M 7000120883 Abrasive Belt 1/2x18 in Aluminum Oxide Medium

Product Description

The 3M 7000120883 is a non-woven abrasive belt designed for surface finishing, blending, and deburring applications in metalworking and fabrication environments. Measuring 1/2 inch wide by 18 inches long, this belt runs on compatible narrow-belt and file-belt sanders used by machinists, pipefitters, welders, and maintenance technicians. The abrasive material is aluminum oxide in a medium grade, bonded to a scrim backing that provides flexibility and conformability on curved or contoured surfaces. The non-woven construction delivers consistent scratch patterns and resists loading, making it suitable for both wet and dry operation.

This belt is suited for light stock removal, surface conditioning, and weld blending on metal components. Its narrow 1/2-inch width fits file-belt sanders commonly used in tight-access areas such as pipe joints, tube assemblies, and machined part edges. The SE-BS series non-woven construction makes it a practical choice for shops requiring a consistent finish without aggressive material removal. Both wet and dry use are supported, allowing flexibility depending on the workpiece material and finish requirement.

Installation Notes

Belt installation should be performed by a qualified technician familiar with abrasive tooling. Power down and disconnect the sander from its power source before changing belts. Confirm belt tracking and tension per the tool manufacturer guidelines before resuming operation. Wear appropriate PPE including eye protection and gloves when handling abrasive belts and operating grinding or finishing equipment.
