3M 7000121066 Deburring Disc 6 Inches Very Fine

Product Description

The 3M 7000121066 is a 6-inch aluminum oxide deburring disc designed for surface conditioning, light deburring, and finishing work on metal and other materials. The disc attaches via a hook-and-loop backing, allowing fast disc changes on compatible random orbital and right-angle tools. Rated at a maximum of 4000 RPM, it is built for controlled, low-speed deburring passes where a Very Fine grade is appropriate for smoothing edges without aggressive material removal. Weighing 0.03 pounds, it is a lightweight consumable suited for frequent replacement in production and maintenance environments.

This disc is used in metal fabrication, pipe fitting, HVAC sheet metal work, and general maintenance applications where burrs or sharp edges need to be addressed after cutting or drilling. It is typically used by machinists, pipefitters, HVAC technicians, and maintenance mechanics working on ferrous and non-ferrous metals. The Very Fine grade makes it appropriate for final-pass deburring and light surface prep rather than heavy stock removal.

Installation Notes

Attach the disc firmly to a compatible 6-inch hook-and-loop backing pad before use. Verify the tool's rated RPM does not exceed 4000 RPM before mounting the disc. Inspect the disc for tears or damage before each use and discard if the abrasive face or backing shows signs of wear or separation. Follow applicable shop safety practices including eye protection and workpiece securing.
