Grit Table / sandpaper / CAMI wet/dry sandpaper (3M Wetordry and peers)
Product that conforms
Coated abrasive
This product conforms to a grading standard and inherits its distribution. Where the standard defines a spread the product gets it, otherwise a single point.
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.
