3M 7000046161 Scotch-brite Bristle Disc 3 Inch Ceramic

Product Description

The 3M 7000046161 Scotch-Brite Radial Bristle Disc is a ceramic abrasive disc designed for surface preparation, coating removal, and finishing work across metal and other hard substrates. Built with proprietary ceramic abrasive grain molded directly into flexible bristles, the disc delivers consistent cutting action throughout its full service life. At 3 inches in diameter with a curved profile and center hole, it mounts to standard rotary tools used by fabricators, welders, maintenance technicians, and industrial finishing crews. The ceramic grain provides aggressive material removal without requiring heavy operator pressure.

This disc is suited for removing paint, rust, heavy oxides, weld burns, adhesives, stains, and surface contaminants from large or contoured surfaces. The curved bristle geometry and flexible construction allow the disc to conform to irregular profiles and complex part geometries, making it practical for both flat and contoured work. It is commonly used in metal fabrication shops, maintenance and repair operations, and industrial finishing environments where consistent surface prep is required across repeated cycles.

Key Features

• Ceramic abrasive grain molded into flexible bristles maintains cutting performance throughout disc life
• Curved profile and flexible bristles conform to contoured and complex part surfaces
• Removes paint, rust, weld burns, heavy oxides, adhesives, and surface contaminants
• Requires less operator pressure than wire brushes for stripping, deburring, blending, and finishing
• Contains no wire filaments, reducing safety risk from wire fragment ejection
• Bristle spacing optimized for high-loading removal applications such as coatings and adhesives

Compatibility

Designed as an OEM-style abrasive disc for use with rotary tools and angle grinders that accept 3-inch diameter disc accessories with a center hole mounting configuration.

Installation Notes

Installation and operation should be performed by personnel familiar with rotary abrasive tooling and applicable shop safety standards. Verify that the tool spindle speed does not exceed the maximum rated RPM for the disc before mounting. Secure the disc firmly to the arbor before powering on the tool, and inspect the bristles for damage prior to each use. Always wear appropriate eye and face protection when operating abrasive discs.
