3M 07525 Bristle Disc, 2" Yellow, 80 Grit, 10-Pack
Wire-Free Molded Bristle Safety – 3M Bristle Disc (07525, 2" 80 Grit, 10-Pack)
Revolutionary Molded Bristle Technology for Safe, Aggressive Surface Conditioning
The 3M Bristle Disc 07525 delivers 4× longer life than traditional wire wheels while eliminating 100% of wire contamination risks through revolutionary molded polymer bristles. This 2-inch yellow disc combines aggressive ceramic aluminum oxide cutting with safe molded bristles, removing coatings 30% faster while running cooler than conventional abrasives. Each bristle is impregnated with abrasive particles throughout its structure, ensuring steady cutting action from first use to last.
Key Benefits That Set This Disc Apart
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.
