3M 07525 Bristle Disc, 2" Yellow, 80 Grit, 10-Pack
Molded Bristle Safety – 3M 07525 Bristle Disc (2", 80 Grit, 10-Pack)
Revolutionary Molded Bristle Technology for Safe, Aggressive Surface Conditioning
The 3M Bristle Disc 07525 redefines surface preparation by combining aggressive ceramic aluminum oxide cutting with safe molded polymer bristles. This 2-inch yellow disc eliminates wire contamination risks while delivering consistent performance on coating removal, rust cleaning, and surface conditioning tasks. Each bristle is impregnated with abrasive particles, ensuring steady cutting action from first use to last.

Game-Changing Benefits for Professional Users
Zero Wire Contamination Risk
Molded bristles eliminate the hazards and debris of wire wheels. No broken wires to embed in workpieces or cause injuries, and no ferrous contamination on non-ferrous surfaces.
4× Longer Life Than Wire Brushes
Ceramic aluminum oxide infused throughout each bristle maintains cutting efficiency until full wear. Unlike surface-coated abrasives, these discs deliver consistent performance throughout their extended lifespan.
Conformable Design for Complex Shapes
Flexible bristles adapt to contours, radii, and irregular geometries without gouging. Perfect for weld seams, flange faces, and recessed areas where traditional discs struggle.
Runs 30% Cooler Than Alternatives
Open bristle structure promotes airflow and heat dissipation, preventing workpiece discoloration and protecting heat-sensitive substrates.
Proven Applications Across Industries
Automotive Collision Repair & Restoration
Ideal for seam sealer removal, paint stripping in tight areas, and rust remediation without thinning panels or causing heat warpage. Perfect for door jambs, trunk channels, and body seams.
Industrial Maintenance & Equipment Refurbishment
Excellent for gasket removal, flange face prep, and corrosion cleaning on pumps, valves, and housings—preserves sealing surfaces for leak-free reassembly.
Metal Fabrication & Welding Operations
Removes weld spatter, mill scale, and oxidation without undercutting. Maintains base metal dimensions and prepares surfaces for coating or plating.
Marine & Aerospace Applications
Safe for non-ferrous metals and composites—no contamination risk. Used for corrosion removal, coating stripping, and composite repair without substrate damage.

Installation & Usage Guidelines
Required Equipment
Use with a 2" Roloc TR disc pad (e.g., 3M 45090) on a die grinder or angle grinder. Ensure tool speed is within 15,000–20,000 RPM for best results.
Best Practices
- Speed Control: Maintain 15–20K RPM to avoid premature wear
- Light Pressure: Let bristles do the work—excessive force reduces effectiveness
- Angle: 5–15° for optimal bristle engagement and debris clearance
- Motion: Overlapping circular strokes for uniform finish
Frequently Asked Questions
How do bristle discs compare to wire wheels?
Bristle discs maintain steady cutting action without embedding wires in workpieces. They run cooler, resist loading, and offer safer, more consistent performance than wire wheels.
Why is the disc yellow?
Yellow indicates 80 grit—medium aggressiveness ideal for coating removal and rust cleaning. Other colors (green 50 grit, white 120 grit) serve heavier or finer applications.
Can I use on aluminum and stainless steel?
Yes—no ferrous contamination risk. Ceramic abrasive cuts non-ferrous metals safely without causing corrosion or substrate damage.
How many square feet per disc?
Expect 15–25 sq ft per disc for moderate coatings; heavy rust reduces coverage to 10–15 sq ft. Consistent wear ensures predictable project planning.
What causes premature wear?
Excessive pressure and speeds above 20K RPM. Ensure correct mounting and operation within recommended parameters for maximum disc life.
