3M 7000000749 Scotch-brite Bristle Disc 3 Inch P120

Product Description

The 3M 7000000749 is a Scotch-Brite Radial Bristle Disc designed for surface preparation tasks including paint removal, rust stripping, weld burn cleanup, oxide removal, and adhesive residue removal. The disc uses proprietary 3M ceramic abrasive grain molded directly into flexible bristles, which provide consistent cutting action from first use through the end of the disc life. At 3 inches in diameter with a P120 grit rating, it suits detail work and mid-size surface areas. Licensed tradespeople and maintenance professionals in metal fabrication, HVAC, and general industrial service install and operate this disc on compatible angle grinders and rotary tools.

This disc is suited for use on metal surfaces where wire brushes would risk contamination or leave embedded filaments. The curved, flexible bristle design conforms to contours and irregular geometries, making it appropriate for deburring, blending, finishing, and cleaning on complex parts. It handles high-loading substances such as coatings and heavy oxides across both flat and contoured work surfaces. Typical applications include prep work before welding or coating, post-weld cleanup, and corrosion removal in residential and light commercial maintenance settings.

Key Features

• Proprietary ceramic abrasive grain delivers aggressive cutting and consistent finish quality throughout disc life
• Flexible, abrasive-filled bristles conform to contours without the need for heavy operator pressure
• Contains no wire filaments, reducing risk of filament embedment and improving worksite safety
• Bristle spacing optimized for coating removal and high-loading surface contaminants
• 3 inch diameter at P120 grit suits detail surface prep and mid-size area treatment
• Curved disc geometry increases surface contact compared to flat wire brush alternatives

Compatibility

Designed for use with compatible rotary tools and angle grinders that accept 3 inch radial bristle disc accessories. Confirm arbor size and RPM rating of the host tool against disc specifications before installation.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with rotary abrasive tool safety. Power down and disconnect the host tool before mounting or removing the disc. Verify that the tool RPM rating does not exceed the disc rated speed before operation. Eye protection and appropriate PPE are required when operating abrasive discs.
