Hi, after truing I understand the wheel is 220 grit, what is the micron value

  • Hej Anthony

    You can´t determin that, there are different charts and standards which makes it impossible to compare. When using the surface it will change immediately due the cracking of the sharpening particles. This is also influenced by the pressure and sharpening angel. After truing the surface is for example very aggressive and gets finer, and a fine adjusted grid with the SP-650 Stonegrader is getting after a while more coarse.
    I hope I could answer your question.
