3M 7000121947 Abrasive Belt Non-woven Ao 18x3/4 Inch

Product Description

The 3M 7000121947 is a Standard Abrasives Surface Conditioning RC Belt designed for one-step surface preparation ahead of final finishes and coatings. Constructed from non-woven aluminum oxide (AO) on an RC backing, this belt measures 18 inches in length and 3/4 inch in width. It delivers high initial and extended cut rates while maintaining flexibility and edge durability throughout the belt's service life. Technicians and fabricators in metalworking and composites shops use it to streamline prep work by combining multiple steps into a single pass, reducing overall labor time without sacrificing finish quality.

This belt is well suited for deburring, blending, cleaning, and finishing operations on composites and softer metals. Its non-woven construction makes it particularly effective on flat surfaces, and it serves as a reliable starting point when finishing stainless steel to a 4 finish. The aluminum oxide abrasive on RC material maintains a consistent cut rate under average pressure, making it appropriate for general-purpose shop use across a range of surface conditioning tasks.

Key Features

• Non-woven aluminum oxide construction provides good initial and extended cut rate
• High edge durability and flexibility for consistent performance across the belt width
• Suitable starting point for finishing stainless steel to a 4 finish
• One-step prep: handles blending, coating removal, finishing, and light deburring
• RC backing performs best on flat surfaces under average pressure
• Effective on composites and softer metals

Compatibility

Designed for use on compatible belt-drive surface conditioning tools accepting 18-inch by 3/4-inch non-woven abrasive belts; suitable for general-purpose metalworking and composite surface preparation applications.

Installation Notes

Installation should be performed by qualified shop personnel familiar with abrasive belt equipment. Power down and lock out the tool before changing belts.
