3M 7010299279 Bristle Disc 1 in 120 Grit Ceramic

Product Description

The 3M 7010299279 is a Scotch-Brite Roloc Bristle Disc designed for surface preparation, coating removal, deburring, blending, and finishing on metal and other substrates. The disc uses a proprietary ceramic abrasive grain blended with aluminum oxide, molded directly into flexible bristles. This construction allows the disc to maintain its cutting and finishing properties throughout its full service life rather than degrading as surface abrasive wears away. At 1 inch in diameter and 120 grit, it fits tight spaces and contoured workpieces where larger discs cannot reach. The Roloc quick-change attachment system makes disc swaps fast during multi-step finishing sequences. Typically installed and operated by machinists, fabricators, and maintenance technicians.

This disc is suited for use on ferrous and non-ferrous metals in both shop and field applications. The flexible, abrasive-filled bristles conform to irregular surfaces and complex contours, producing consistent finishes even on curved or recessed geometry. Common tasks include weld prep, rust and coating removal, light deburring, and surface blending before paint or coating application. The 1 inch diameter fits die grinders and right-angle tools equipped with a TR Roloc-style mandrel. The bristle spacing is optimized for high-loading applications such as heavy coating removal where clogging would be a concern with conventional abrasive products.

Key Features

• Ceramic abrasive grain blended with aluminum oxide provides consistent cut and finish throughout disc life
• Flexible, abrasive-filled bristles conform to contours for uniform results on complex parts
• Suitable for stripping, deburring, blending, finishing, polishing, cleaning, and coating removal
• Bristle spacing reduces loading and clogging during heavy-duty coating removal
• Roloc TR quick-change attachment allows fast disc swaps in multi-step finishing workflows
• 1 inch diameter accesses tight areas and confined geometry inaccessible to larger discs

Compatibility

Designed for use with TR Roloc-style mandrels on die grinders and right-angle tools. Confirm mandrel thread and shank compatibility with your tool before installation.

Installation Notes

Installation and operation should be performed by qualified technicians familiar with abrasive tool safety. Power down and disconnect the tool before mounting or removing the disc. Verify the tool RPM rating meets or exceeds the disc RPM rating before use. Eye protection, hearing protection, and appropriate gloves are required during operation per standard shop safety practice.
