3M 7000120846 Scotch-brite Coating Removal Disc 7 Inch

Product Description

The 3M 7000120846 is a Scotch-Brite Hook-It CR-DH Coating Removal Disc designed for aggressive surface prep on metal. Built from a conformable, open-web non-woven material impregnated with extra coarse (XCS) silicon carbide mineral, this disc strips paint, rust, and welding scale without gouging or undercutting the base material. At 7 inches in diameter and rated to 6000 RPM, it fits angle grinders and random orbital tools equipped with a hook-and-loop backing plate. Fabricators, welders, and metal finishing technicians use it to prep surfaces before priming, coating, or further abrasive operations.

This disc is suited for coating removal and surface preparation on ferrous and non-ferrous metal, including flat plate, welded assemblies, and structural sections. It cleans welding scale, heat discoloration, and seam areas while preserving the workpiece geometry. The open-web construction runs cooler than bonded abrasive discs and resists loading during extended operation, making it practical for multi-step finishing sequences where consistent surface profile is required. Minimum order quantity is 10 units per pack.

Key Features

• Extra coarse (XCS) silicon carbide mineral removes paint, rust, and scale aggressively
• Conformable non-woven construction maintains workpiece geometry and avoids undercutting
• Open-web material dissipates heat and resists loading for prolonged use
• Hook-and-loop attachment allows fast disc changes in multi-step finishing processes
• Outperforms wire brushes for coating removal and surface prep efficiency

Compatibility

Designed for use with 7-inch hook-and-loop angle grinder or right-angle disc tool backing plates rated to a minimum of 6000 RPM. No specific OEM system compatibility was provided in the product data.

Installation Notes

Installation and disc changes should be performed with the tool unplugged or the air supply disconnected. Verify the backing plate RPM rating meets or exceeds the 6000 RPM disc rating before mounting. Inspect the disc for tears or separation before each use and discard any damaged disc immediately. Eye protection, hearing protection, and appropriate respiratory protection should be worn during operation per applicable ANSI and OSHA guidelines.
