• IDEAL FOR LOW TO MEDIUM PRESSURE APPLICATIONS: Built to ensure consistent uniformity, cleaning, deburring, finishing, grinding, polishing, shoring, refining, and surface preparation, depending on the grit selected.
• CONFORMING NON-WOVEN FABRIC: The elastic non-woven fibers resist soiling and adapt to irregular or contoured surfaces, reducing peeling and gouging.
• WORKS ON A VARIETY OF METALS: This versatile option is ideal for aluminum, mild steel, nickel alloy, stainless steel, and titanium.
• QUICK AND EASY MOUNTING: 3M ™ Roloc ™ mounting system for quick and easy disc changes
• CHOOSE YOUR MINERAL: Discs are available in ultra-sharp silicon carbide (SiC), which excels in low-pressure and fine-finish applications, or in harder, more durable aluminum oxide (A/O).

(1) Roloc Disc, 4C (10-Pack)

Will these Roloc™ discs work for surface conditioning and blending?

Yes — 3M 7482 Roloc™ discs are designed for surface conditioning, blending, finishing, and light deburring rather than heavy material removal.

What materials are these 4C discs suitable for?

They work well on metal, stainless steel, aluminum, composites, and other surfaces to clean, smooth, and de-scale without aggressive grinding.

How does the Roloc™ attachment benefit my workflow?

The Roloc™ quick-change system lets you swap discs rapidly without tools, reducing downtime between grit changes and speeding up jobs.

Are these discs durable and long-lasting?

Yes — the nonwoven conditioning material resists loading and wear, offering consistent performance and longer life compared with traditional abrasive pads.
