3M 7100135079 Scotch-brite Bristle Disc 1 in 36 Grit

Product Description

The 3M 7100135079 Scotch-Brite Radial Bristle Disc is a 1-inch diameter, 36-grit ceramic abrasive disc designed for surface preparation and finishing work on metal and other materials. Molded flexible bristles filled with ceramic abrasive grain deliver aggressive cutting action and consistent finish quality from first use through the end of the disc life. The curved bristle design conforms to contours and complex part geometries, making it well suited for stripping, deburring, blending, and coating removal tasks. Licensed tradespeople and fabricators in HVAC, plumbing, electrical, and general metalwork use this disc with angle grinders and rotary tools.

This bristle disc is used in residential and commercial applications where surface contaminants, rust, heavy oxides, weld burns, paint, stains, and adhesives must be removed efficiently. The flexible bristles conform to irregular surfaces and curved profiles, reducing the need for multiple tool changes when working on fittings, pipe joints, sheet metal, and structural components. It is appropriate for both bench-mounted and handheld rotary tool setups common in trade service environments.

Key Features

• 36-grit ceramic abrasive grain provides aggressive, consistent cutting throughout the disc life
• Molded abrasive-filled bristles strip, deburr, blend, finish, polish, clean, and remove coatings with less applied pressure than wire brushes
• Curved bristle geometry conforms to contours and complex part profiles
• Bristle spacing optimized for coating removal and high-loading surface contaminants
• Contains no wire filaments, reducing the risk of wire fragment ejection during use
• 1-inch diameter suits tight-access areas and small-diameter fittings

Compatibility

Designed for use with angle grinders and rotary tools that accept 1-inch diameter radial bristle disc mandrels. Confirm mandrel compatibility and maximum RPM rating before installation.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with rotary abrasive tool safety. Always confirm the tool RPM rating does not exceed the disc maximum rated speed before mounting. Wear appropriate PPE including eye and face protection, gloves, and hearing protection. Inspect the disc for damage before each use and do not use a disc that shows cracking or missing bristles.
