Conversion Chart Abrasives - Grit Sizes
ANSI is what Norton uses , JIS is for the Japanese stones
ANSI is only defined up to 1200.
What about 4000 and 8000 Norton?
Based on the chart, ANSI rating is directly proportional to grit size in microns, so you can extrapolate any ANSI rating. The same appears to be true for JIS.
This chart shows J2000 roughly equal to ANSI 1000.
But I read elsewhere, that for the same grit number, Naniwa stones are finer than Norton. Were they wrong?
I have read suggestions to go from 8k Norton to 8k Naniwa to 12k Naniwa.
Keep in mind that Grit ratings are at best within each series of hones if you start switching series and brand they become meaningless very fast...
I am trying to remember any thread on here (SRP) that mentions stacking a Norton 8k and a Naniwa 8k in a progression and just can't
Actually, the Norton, Naniwa SS and Chosera and the Shapton 8K's results are quite similar. Little different feeling on each stone though.
Have fun,
