3M Scotch Brite Disc SC-DH 125 mm – very fine abrasive disc

Scotch Brite Disc 3M SC-DH 125 mm is a very fine abrasive disc designed for surface finishing, blending, cleaning and light deburring. The non-woven construction provides consistent, conformable abrasive action across irregular surfaces, helping to produce smooth, uniform finishes on metal, painted surfaces and composites. The 125 mm diameter suits handheld random orbital sanders and angle grinders with compatible backing pad systems, delivering controlled material removal without aggressive gouging.

Advantages

The very fine abrasive texture offers gentle yet effective surface conditioning, reducing the risk of damaging underlying material. The non-woven structure resists loading and maintains consistent performance over the disc life. Its conformability allows access to contours and edges while preserving surface profile. The disc is suitable for use on a variety of substrates and supports repeatable finish quality for preparation prior to painting, coating or polishing.

Suitable for

• Surface finishing and blending on steel, stainless steel and aluminum
• Cleaning and light deburring of welded joints and formed parts
• Preparing painted surfaces and composites for repainting or coating
• Feathering edges and removing surface imperfections without deep scratches

Key specifications

• Abrasive grade: very fine (non-woven)
• Diameter: 125 mm
• Construction: non-woven abrasive web
• Application method: rotary or orbital machines with compatible backing pad
• Suitable substrates: metals, painted surfaces, composites

How to use

Attach the 125 mm disc to a compatible backing pad and secure it according to the tool manufacturer’s instructions. Start the machine at a moderate speed and apply light, even pressure while moving the disc across the work surface to avoid concentrated wear or overheating. For best results, maintain consistent motion and check progress frequently. Replace the disc when abrasive action diminishes or surface finish requirements are no longer met.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, gloves and respiratory protection if dust is generated. Match disc speed and tool type to the backing pad and follow the machine manufacturer’s safety guidelines. Test on a small area before full treatment to confirm the finish and suitability for the substrate.
