The 3M 50mm Roloc Disc SC-DR Blue Very Fine Scotch-Brite is a surface conditioning disc designed for professionals in aerospace, automotive, collision repair, general industrial, and manufacturing sectors. It is engineered to clean, finish, blend, and deburr metal and other substrates effectively.

This disc features a durable, non-woven fibre construction that conforms to irregular or contoured surfaces, preserving the integrity of the workpiece. The open-web design resists loading and runs cool, reducing the risk of part discoloration and warping during use. The Roloc backing system allows for quick and secure disc changes, enhancing efficiency in multi-step finishing processes.

Aluminum oxide abrasives are incorporated into the non-woven nylon or synthetic fibres, providing a high cut rate and consistent finishing performance. Aluminum oxide is favored in industrial applications due to its toughness, long life, and ability to self-fracture, exposing fresh cutting edges. It is suitable for a wide range of substrates, including ferrous alloys, making this disc versatile for metal fabrication tasks.

The 3M Roloc TR quick change system includes a plastic threaded button or screw that easily attaches to a Roloc TR disc pad (sold separately), enabling fast disc replacement with a simple twist-on, twist-off motion. This system ensures secure attachment even in heavy-duty applications and supports seamless transitions between different finishing tasks.
