3M 7000046011 Scotch-brite Coating Removal Disc 4.5 in

Product Description

The 3M 7000046011 Scotch-Brite CR-DH Coating Removal Disc is a 4.5-inch non-woven abrasive disc designed for stripping paint, rust, and coatings from metal surfaces and welds. Built with extra coarse silicon carbide mineral, it cuts aggressively without gouging or undercutting the base material. The conformable, open-web construction runs cool during operation and resists loading, which extends disc life during prolonged use. It attaches via a hook-and-loop system for fast disc swaps in multi-step surface prep workflows. HVAC fabricators, pipefitters, welders, and general metal tradespeople are the primary installers of this type of abrasive tooling.

This disc is suited for surface preparation on metal substrates in both light industrial and trade settings. Common applications include removing welding scale, discoloration, and seam cleanup on sheet metal, pipe, and structural steel. Its non-woven construction maintains workpiece geometry, making it appropriate for use on contoured or hard surfaces where wire brushes risk distorting the material profile.

Key Features

• Extra coarse silicon carbide mineral removes paint and rust effectively from metal surfaces and welds
• Non-woven, conformable construction prevents gouging, undercutting, or base material damage
• Open web design runs cool and resists loading for longer service life
• Hook and loop attachment allows fast disc changes in multi-step finishing processes
• Cleans welding scale, discoloration, and seams more effectively than wire brushes
• Maintains workpiece geometry on hard or contoured surfaces

Compatibility

Designed for use with 4.5-inch hook-and-loop compatible angle grinders and disc tools suitable for non-woven abrasive discs in coating removal and surface preparation applications.

Installation Notes

Installation of abrasive discs should be performed with the grinder or tool unplugged or powered down completely before disc change-out. Verify the tool's maximum RPM rating is compatible with the disc before operation. Operators should wear appropriate PPE including eye protection and gloves when using abrasive discs on metal surfaces.
