WebJan 1, 2009 · In the U.S., most of us are very familiar with the SPI’s standard surface finish definitions, such as an A-1 diamond buff, C-1 Grit Stone or a B-2 Grit Paper finish. As you can see, the RA equivalent value of that A-1 diamond buff is a 0 – 1µ, while the C-1 Stone finish has a 10 – 12µ RA value and the B-2 Paper finish has a 4 – 5µ RA ...
