Steel Grit

THOMAS ABRASIVES Cast Steel Angular Grit is produced by crushing specifically heat treated shot pellets.  Service characteristics depend upon hardness selection.
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.
