Bristle Discs

3M Roloc Bristle Discs are flexible abrasive discs designed for controlled cleaning, coating removal, deburring, blending, and surface preparation. The abrasive bristles conform to contours and irregular surfaces, making them useful for detailed work where controlled material removal is important.

BAC offers 3M Roloc Bristle Discs in 2" diameter configurations and multiple grades, allowing aircraft maintenance technicians to select the appropriate level of aggressiveness for the task.

3M Roloc Bristle Discs for Aircraft Maintenance

Roloc Bristle Discs are useful when a technician needs to remove surface contamination, coatings, corrosion products, adhesives, or other unwanted material without using a conventional rigid abrasive wheel. The flexible bristles can reach contours, edges, corners, and other areas that can be difficult to work with flat sanding discs.

The quick-change Roloc attachment system also makes it practical to switch between abrasive grades during a job. A compatible Roloc backing pad remains mounted to the tool while the abrasive disc is changed.

Available Roloc Bristle Disc Grades

Actual performance depends on the specific disc, substrate, operating conditions, and application. Select the appropriate grade according to the manufacturer's recommendations and the requirements of the maintenance procedure.

Common Aircraft MRO Applications

• Removing paint, coatings, and surface residues
• Cleaning metal surfaces
• Removing adhesives and sealant residue
• Removing oxidation and corrosion products
• Deburring edges and components
• Blending and surface conditioning
• Preparing surfaces for subsequent finishing operations
• Cleaning difficult-to-reach or contoured areas

When working on aircraft components, use the abrasive and grade appropriate for the substrate and the maintenance procedure. Avoid unnecessary material removal from critical components.

Flexible Bristle Construction

Unlike a conventional flat sanding disc, a bristle disc uses individual abrasive-filled bristles to contact the work surface. This construction provides a flexible contact pattern that can conform to irregular surfaces while allowing the operator to maintain control over the amount of material being removed.

This makes bristle abrasives particularly useful for cleaning and surface preparation where maintaining the underlying geometry is important.

Roloc Quick-Change Attachment

These discs are designed for use with a compatible 3M Roloc backing pad. The quick-change attachment allows technicians to change discs efficiently when moving between different grades or applications.

Always verify the disc diameter, backing pad, tool connection, operating speed, and manufacturer's operating instructions before use.
