Sharpening Stone Grit Chart

After discussing the topic of grit coarseness and fineness we decided to come up with our own chart. Since one person's "fine" and one manufacturers "fine" may mean something completely different we established a 1 to 10 grit chart with 1 being the most coarse and 10 being the most fine. This allows you to better understand what each grit is used for and make a more educated buying decision.

Additives for dry milling - fritsch

With an abrasive sintered corundum (Al2O3) grinding set, the hard stems can be comminuted faster. The disadvantage of an “abrasive” grinding set is an early adhering of the particles even though a homogenous sample is achieved with a relatively close grain size spectrum, but with values in a coarser grain size range. For the utilization of sintered corundum this means: a) brief grinding ...
