I asked EZ-lap in November of 2012 and was told:
SF – 1200 grit = 15 to 20 microns
F – 600 grit = 30 to 35 microns
M – 400 grit = 40 to 45 microns
C – 250 grit = 50 to 55 microns
XC – 150 grit = 60 to 65 microns
I’m not sure how accurate these are, but that is what they said. My 220 micron DMT feels *much* coarser than the C EZE-lap. To be honest, I’m not sure if that is a coarseness difference or difference in the amount of abrasive on the plate, DMT vs. EZE lap.
Hope that helps.
