3M 7000121851 Quick Change Abrasive Disc 3 Inch

Product Description

The 3M 7000121851 is a non-woven quick change abrasive disc designed for light-duty surface finishing, cleaning, deburring, and blending on metallic substrates. The disc uses an aluminum oxide abrasive bonded to a tough nylon web construction that resists tearing while delivering a consistent, professional finish. The quick change attachment system locks securely to compatible right-angle tools, reducing disc swap time and keeping operators productive. At 3 inches in diameter, this disc is suited for working smaller surface areas where precision and control matter. The maroon color indicates a moderately aggressive cut grade, making it versatile across a range of light industrial tasks.

This disc is used in light industrial and fabrication environments where operators need to blend welds, clean mill scale, remove burrs, or finish metal surfaces without gouging or distorting the workpiece geometry. The open web construction resists loading, so debris does not rapidly clog the abrasive surface, extending service life during continuous use. Typical users include metal fabricators, maintenance technicians, and trade professionals working with ferrous and non-ferrous metals in production or repair settings.

Key Features

• Non-woven nylon web resists tearing and maintains part geometry without gouging the substrate
• Open web design is load resistant, limiting debris buildup and extending disc life
• Moderately aggressive aluminum oxide abrasive handles cleaning, deburring, and light blending in one disc
• Quick change attachment provides secure tool mounting and fast disc swaps for improved efficiency
• 3 inch diameter suits smaller surface areas requiring precision control
• Maroon grade works on most ferrous and non-ferrous metals

Compatibility

Designed for use with quick change right-angle tools and holders that accept standard 3 inch non-woven abrasive discs.

Installation Notes

Install and remove the disc only when the tool is powered off and disconnected from its air or electrical supply. Ensure the quick change mandrel and retention hardware are in good condition before mounting the disc. Inspect the disc for damage before each use and do not exceed the maximum RPM rating of the tool or disc. Wear appropriate eye protection and respiratory protection when operating abrasive tools on metal.
