probably the grit size for garnet. i think i'm using 20/40 something like that. i gotta double check but it's good for all around use. i just got my new ceramic tips for my blaster(cheap ones from craftsman $6 for 2) went to go change them out and the original tip was stuck and came out in 3 pieces. worn all the way through and started to eat the aluminum gun nose. i was wondering why i wasn't getting good pressure lately while blasting... it's one of those consumables...
