3M 7000121130 Abrasive Belt 3/4x18 in Aluminum Oxide Medium

Product Description

The 3M 7000121130 is a non-woven aluminum oxide abrasive belt designed for light material removal, surface blending, and finishing on metal and similar substrates. Measuring 3/4 inches wide by 18 inches long, this medium-grade belt fits compact belt sanders and inline tools commonly used in fabrication, maintenance, and finishing applications. The low-stretch backing maintains consistent belt tension during operation, and the non-woven construction allows the abrasive to conform to contoured or irregular surfaces. Suitable for both wet and dry operation, the belt holds up under varied working conditions without rapid breakdown.

This belt is well suited for deburring, light stock removal, and weld blending on metal parts in shop and field settings. The 3/4-inch width fits narrow-throat belt sanders and portable finishing tools used by metal fabricators, maintenance technicians, and industrial service professionals. The DF-BL series construction delivers consistent cutting action throughout the life of the belt, making it a practical choice for repetitive finishing work in both production and one-off repair scenarios.
