P5000, decoded.

P5000 is past the end of the published FEPA table, which stops at P2500, and 3M gives its P5000 Trizact disc no A-grade. There is no micron figure we can cite. All we can say is that it is finer than P3000, which 3M pairs with A5.

Questions people ask

How many microns is P5000?

Nobody we can cite publishes one. The FEPA table stops at P2500 and 3M gives its P5000 Trizact disc no A-grade. All we can say is that it is finer than P3000, which 3M pairs with A5.

Convert any other grade, from CAMI, microns or a Trizact A-number, on the grit converter.

Sizes are average particle diameters from the published FEPA (ISO 6344) and CAMI (ANSI B74.12/B74.18) tables. "Nearest" means within 10%; otherwise both neighbors are shown. Trizact pairings are 3M's own. Sources: Wikipedia, "Sandpaper" grit table (rev. 1127917881); Klingspor coated abrasives grit chart; 3M Trizact A-to-P table.
