The chart below shows both the US Mesh and European (FEPA) grit sizes compared to the Eagle Superabrasives standard designation. As you can see in the chart, Eagle Superabrasives grit sizes range from as coarse as 60-grit to over 2,000-grit.
On our packaging and wheel identification, we designate the grit with either a D or B in front of the grit size. The D represents Diamond and B represents CBN.
Grit sizes of 500 or finer are designated as micron sizes. Micron-grit wheels are typically used for polishing in applications with strict finish requirements.
