Suehiro Cerax (New Cerax)

Waterstone

No particle size in microns is published for this line. The values are our estimates from secondary sources, so the marks are faded and the spread is unknown.

Each grade below shows its size in microns, its spread (the published distribution, where a maker or standard gives one; most makers publish none), and where that size lands on the reference scale, a shared yardstick for reading grit numbers across makers.
