3M 7000121948 Surface Conditioning Belt 18x3/4 Inch Ao

Product Description

The 3M 7000121948 is a non-woven aluminum oxide surface conditioning belt designed for one-step workpiece preparation before final finishes and coatings. Measuring 18 inches in length and 3/4 inch in width, this belt is built with enhanced edge durability and flexibility to maintain consistent performance across the cut. The aluminum oxide abrasive on RC material delivers a good initial and extended cut rate, making it well-suited for deburring, blending, cleaning, and finishing operations on composites and softer metals. HVAC sheet metal fabricators, metalworkers, and maintenance technicians handling light surface prep work are the primary users.

This belt is most effective on flat surfaces and operates efficiently under average pressure. It serves as a reliable starting point for finishing stainless steel to a 4 finish and handles coating removal and light deburring in one pass. The RC non-woven construction gives the belt flexibility that reduces loading and maintains conformability against the workpiece surface. Typical applications include shop fabrication, maintenance repair, and surface prep in light manufacturing environments.
