3M 7000120854 Scotch-brite Roloc Disc 4 Inch 12000 Rpm

Product Description

The 3M 7000120854 is a Scotch-Brite Roloc Surface Conditioning Disc designed for cleaning, finishing, blending, and deburring metal and other surfaces. Built on a non-woven fiber construction, the disc conforms to irregular and contoured surfaces without removing base material or altering part geometry. The Roloc quick-change backing allows fast disc swaps during multi-step finishing operations. Rated to 12000 RPM and measuring 4 inches in diameter, this disc is a practical choice for fabrication shops, maintenance technicians, and metal finishing professionals who need consistent results across varied surface conditions.

This disc is suited for use in light fabrication, weld blending, surface prep, and deburring applications on metal workpieces. The open-web, non-woven construction resists loading and runs cool, making it effective for extended use without glazing or heat buildup. The Roloc attachment system threads directly onto compatible Roloc mandrels, supporting use with standard angle grinders and die grinders. It is appropriate for both production and maintenance environments where quick disc changes between finishing steps are required.
