3M 7000120855 Scotch-brite Roloc Disc 4 Inch Silicon Carbide

Product Description

The 3M 7000120855 is a Scotch-Brite Roloc Surface Conditioning Disc designed for cleaning, finishing, blending, and deburring metal and other surfaces. The disc uses a non-woven fiber construction that conforms to irregular and contoured workpieces, reducing the risk of gouging or flattening curved profiles. Silicon carbide abrasive provides consistent cutting action across a range of surface conditioning tasks. The Roloc quick-change backing system allows fast disc swaps without tools, making it practical for multi-step finishing operations in fabrication, maintenance, and repair environments.

This disc is suited for metalworking applications where surface prep, deburring, or blending is required. The open-web construction resists loading and dissipates heat, helping the disc run cooler and deliver consistent finishes across extended use. The 4-inch diameter is a common size for angle grinders and die grinders equipped with a Roloc-compatible mandrel. Typical users include metal fabricators, maintenance technicians, and industrial tradespeople working on ferrous and non-ferrous materials.
