Description
The 3M 7100264089 is a surface conditioning disc designed for quick and consistent surface preparation on metals and alloys. This 3M Scotch-Brite Roloc 2-inch PN-DR medium disc combines precision-shaped ceramic grain with a heavy-duty nonwoven web for aggressive cutting and long-lasting performance without changing part geometry. When working on stainless steel, carbon steel, aluminum, and nickel alloys, the open-web construction resists loading while maintaining the cut rate. The Roloc attachment system facilitates multi-step workflows by allowing for quick, tool-free disc changes. The 3M 2" Roloc disc is ideal for blending, deburring, finishing, and radiusing applications that require a consistent surface finish and quick changeover time. PN-DR medium grade is recommended when an engineered balance of cut and finish is required in production or repair settings.
Product Features and Benefits
Precision-shaped ceramic grain
Triangular ceramic mineral embedded in the nonwoven web slices the material for faster cut rates and longer abrasive life than conventional grains.
Open-web nonwoven construction
The 3M Surface Conditioning Disc has an open structure that resists loading with paints and oxides, exposing cutting surfaces for consistent performance and a longer useful life.
Roloc quick-change attachment
The 3M Scotch Brite Roloc 2-inch interface allows for quick, secure disc swaps, reducing downtime and speeding up the blending, refining, and finishing process./p> Medium grade for multi-purpose use
PN-DR medium grade balances stock removal and surface refinement for deburring, cleaning, and finishing on a variety of substrates..
Conformable, non-gouging action
3M Roloc Scotch-Brite Discs' nonwoven fiber construction conforms to contours and edges, making cleaning and finishing possible without undercutting or damaging the surrounding material.

Frequently Asked Questions
What are 3M Roloc Scotch-Brite discs used for?
They are used to blend, refine, deburr, clean, and finish metals and composite surfaces.
Is this 2-inch Roloc disc suitable for aluminum work?
Yes, the precision-shaped ceramic and open web make it suitable for aluminium finishing and oxide removal.
How do the 3M Roloc bristle disc for aluminum and the Roloc PN-DR compare?
PN-DR nonwoven discs have a conformable, open-web finish, whereas bristle discs are stiffer for aggressive profiling and edge work.
What equipment accepts this 2-inch 3M Roloc disc?
Designed for disc sanders and hand tools with a Roloc pad or adapter that accepts 2" Roloc attachments.
