3M 7000121013 7 Inch Non-woven Surface Conditioning Disc Fine

Product Description

The 3M 7000121013 is a 7-inch diameter, non-woven surface conditioning disc designed for heavy-duty deburring and finishing on metal and fabricated components. It uses a hook and loop attachment system for fast disc changes during multi-step finishing work. The open-web, non-woven fiber construction resists loading and runs cool, which helps maintain consistent finishes across a workpiece. Rated to 6000 RPM, this disc is built for use on angle grinders and disc sanders in demanding production or maintenance environments. Fine grit aluminum oxide abrasive makes it well suited for edge deburring and surface prep without removing base material.

This disc is intended for deburring, blending, and light stock removal on metal surfaces including flat panels, contoured parts, and irregular edges. Its conformable construction allows it to follow surface contours closely, which preserves edges and reduces the risk of over-grinding. It is commonly used in metal fabrication shops, maintenance and repair operations, and industrial finishing lines where controlled material removal and consistent surface quality are required. Licensed tradespeople and skilled shop technicians are the primary installers and operators.

Key Features

• Non-woven fiber construction conforms to irregular and contoured surfaces for controlled finishing
• Open-web design resists loading and dissipates heat, supporting consistent finish quality
• Hook and loop attachment system allows quick disc changes between finishing steps
• Fine grit aluminum oxide abrasive provides aggressive cut without damaging base material
• Rated to 6000 RPM for compatibility with standard angle grinders and disc sanders
• Delivers greater cut and longer service life compared to standard SC and PD surface conditioning discs

Compatibility

Designed for use with hook and loop backing pad systems on angle grinders and disc sanders that accept 7-inch discs and operate within a 6000 RPM speed rating.

Installation Notes

This disc is installed and operated by metalworkers, fabricators, and maintenance technicians. Before mounting, confirm the backing pad and grinder are rated for the disc diameter and maximum RPM. Inspect the disc for damage before each use and do not exceed the rated speed. Always wear appropriate PPE including eye protection and gloves when operating abrasive discs.
