3M 7000000777 Bristle Disc 3 Inch 36 Grit Ceramic

Product Description

The 3M 7000000777 is a 3-inch diameter ceramic abrasive bristle disc designed for aggressive surface preparation on metal and composite substrates. Molded polymer bristles are filled with ceramic abrasive grain and arranged in a radial pattern that resists loading, allowing the disc to cut consistently without clogging. Trades professionals use it for removing rubberized undercoating, seam sealer, rust, and paint, as well as for deburring, blending, and light finishing work. The absence of wire filaments reduces the risk of embedded metal contamination in the work surface.

This disc is suited for automotive body repair, fabrication shops, and maintenance environments where coating removal from contoured or complex surfaces is required. The flexible bristles conform to irregular geometry, making it practical for areas where rigid abrasive tooling loses contact. It is commonly used by body technicians, pipefitters, and general metalworkers who need consistent finish quality across the full service life of the disc.

Key Features

• Ceramic abrasive grain delivers aggressive cutting and consistent finish throughout the disc life
• Radial bristle pattern resists loading on high-debris and coating-heavy substrates
• Flexible bristles conform to contours and complex part geometry
• No wire filaments, reducing risk of metal contamination in the work surface
• Effective for rust removal, paint stripping, seam sealer removal, deburring, and blending
• Requires less pressure than wire brushes to achieve comparable material removal

Compatibility

Designed for use with standard right-angle grinders and die grinders that accept 3-inch bristle disc accessories. Verify spindle compatibility and RPM rating before mounting.

Installation Notes

A licensed or qualified technician should mount and operate this disc following the tool manufacturer's RPM specifications. Disconnect or power down the grinder before mounting or removing the disc.
