More Information


The 85A series is much harder and generates finer particulates compared to A abrasive grains / WA abrasive grains. The life of grindstones will be extended and it also greatly reduces grinding resistance.
Z300 abrasive grains are capable of maintaining their sharpness longer than 32A grindstones as they are fractured into an appropriate size for the grinding of difficult-to-machine SUS300 stainless steel. Also they are less prone to burn marks as they have less deposition on the work material and are capable of realizing a long dressing interval.
