3M 7000136521 Scotch-brite Surface Conditioning Disc 3 Inch

Product Description

The 3M 7000136521 is a Scotch-Brite Hook and Loop Surface Conditioning Disc engineered for cleaning, blending, deburring, and finishing operations on a range of substrates. The disc uses a non-woven fiber construction that flexes and conforms to irregular or contoured surfaces without undercutting or damaging the base material. At 3 inches in diameter, it is sized for right-angle grinders and disc tools commonly used in metal fabrication, composite work, and general surface prep. The open web structure runs cool and resists loading, extending working life across multi-step finishing processes.

This disc is suited for use on metal, composites, plastics, and similar materials in both shop and field environments. The hook and loop attachment system allows fast disc changes, making it practical for sequential finishing operations where multiple grades are used in succession. It is commonly used by fabricators, maintenance technicians, and surface prep professionals who require consistent, controlled material removal without aggressive cutting action.
