GN Steel Grit: Angular when new,
rounds off rapidly in use. Particularly
suited to descaling applications.
GL Steel Grit: While harder than GN grit,
GL also loses sharp edges during use.
Appropriate for descaling and surface
preparation applications.
GH Steel Grit: With maximum hardness,
GH stays angular in the mix, does not shatter
readily and has a fast, effective, etching action.
Ideal for deep descaling and etched surface
requirements. For use mainly with
compressed air equipment
