3M 7100135084 Scotch-brite Bristle Disc 1 in 220 Grit

Product Description

The 3M 7100135084 is a Scotch-Brite Radial Bristle Disc engineered for aggressive surface preparation using proprietary ceramic abrasive grain molded directly into flexible bristle tips. At 1 inch in diameter with a 220 grit rating, this disc strips, deburrs, blends, finishes, polishes, and cleans without the hazards of wire filaments. The curved bristle design conforms to contours and complex geometries, maintaining consistent abrasive contact throughout the full life of the disc. It is installed on rotary tools and used by metal fabricators, HVAC technicians, pipefitters, welders, and maintenance trades requiring controlled surface finishing on metal components.

This disc is suited for use on metal surfaces in both residential and light commercial maintenance and fabrication scenarios. Common applications include removal of paint, rust, weld burns, heavy oxides, adhesives, stains, and surface contaminants from ferrous and non-ferrous substrates. The flexible bristle spacing handles high-loading substances and wide surface areas without loading up quickly. It is commonly used where tight tolerances or irregular contours make rigid abrasive tooling impractical.

Key Features

• Proprietary ceramic abrasive grain delivers aggressive cutting with consistent finish quality from first use to last
• Molded abrasive-filled bristles require less pressure than wire brushes and conform to complex contours
• Contains no wire filaments, reducing risk of wire ejection hazards during operation
• Bristle spacing optimized for coating removal and high-loading surface contaminants
• Curved disc profile maintains surface contact across irregular or contoured workpieces
• 220 grit ceramic construction supports finishing, blending, and polishing stages without aggressive material removal

Compatibility

Designed for use as a radial bristle disc attachment on compatible rotary tools and die grinders accepting 1 inch diameter disc accessories.

Installation Notes

Installation and operation should be performed by qualified trades familiar with rotary abrasive tooling and applicable shop safety standards. Ensure the rotary tool is powered off and unplugged before mounting or removing the disc. Verify the tool RPM rating does not exceed the disc maximum operating speed before use. Eye protection and appropriate PPE are required during operation in accordance with OSHA abrasive wheel standards.
