3M 7100081711 Bristle Disc 1 Inch 36 Grit Ceramic

Product Description

The 3M 7100081711 is a 1-inch diameter ceramic abrasive bristle disc designed for surface preparation and coating removal on metal and composite substrates. The disc uses molded, abrasive-filled polymer bristles arranged in a radial pattern to resist loading and maintain consistent cutting action throughout the disc's service life. Proprietary ceramic abrasive grain delivers aggressive stock removal without the pressure requirements of conventional wire brushes. The open bristle spacing prevents debris buildup, making this disc well-suited for heavy-loading applications. Licensed trades and body technicians use it for stripping rubberized undercoating, seam sealer, rust, and paint.

This bristle disc is used in automotive body repair, metal fabrication, and general industrial surface prep where controlled material removal and contour-following are required. The flexible bristles conform to irregular and complex part geometries, making it effective on curved panels, weld seams, and tight radii. It is appropriate for use on steel, aluminum, and similar metallic substrates. The 36-grit rating positions it as a coarse-duty tool for aggressive stripping and deburring rather than fine finishing work. Installation and use typically falls to auto body technicians, metal fabricators, and maintenance trades.

Key Features

• 1-inch diameter with 36-grit ceramic abrasive grain for aggressive cutting action
• Radial bristle pattern resists loading on high-debris substrates
• Flexible bristles conform to contours and complex part geometries
• No wire filaments — eliminates wire fragment hazards during use
• Effective for removing rubberized undercoating, seam sealer, rust, and paint
• Abrasive-filled bristles strip, deburr, blend, and clean with less applied pressure than wire brushes

Compatibility

Designed for use with compatible rotary tool mandrels and die grinders that accept 1-inch bristle disc attachments. Suitable for surface preparation on steel, aluminum, and similar metallic substrates in automotive and general fabrication applications.

Installation Notes

Mount the disc onto a compatible mandrel following the tool manufacturer's specified torque and attachment procedure. Wear appropriate PPE including eye protection and gloves before operating. Inspect bristles for wear or damage before each use and replace the disc if bristle integrity is compromised. Operate at the RPM rating specified for the disc and mandrel combination — do not exceed rated speed.
