Tough yet conformable,these discs are smear-proof an resist tearing on burrs and sharp edges,use for:

Removing heavy oxidation on the surface

Edge deburring o aluminum extrusions

Blending machine and tool marks and mismatches on all

Structural and engine components

Surface preparation prior to coating
