The most common, highest end, 3µ-ish belt is the Trizact A3.
It is soft. F weight, I believe.
There is an enormous difference between a 3µ Trizact and 4µ PDP, or even CBN, on leather or linen. Trizacts minimize tooth at rated grit. PDP maximizes tooth at rated grit. CBN falls in the middle, but an application doesn't last long.
Linen belts are Much stiffer than F weight cloth as well. I have always liked CBN on linen for deburring, but PDP on leather deburrs without killing tooth.
