• This grinding wheel exhibits excellent grinding performance for a wide range of applications.
• The red whetstone is a whetstone that reduces wear and smooths the spontaneous action of the whetstone.　It is a high performance whetstone that can distinguish uneven firing temperature at a glance compared to a black whetstone.
• The uneven groove line pattern is designed so that the tip of the grinding wheel is at a sharp angle when used to prevent the upper surface from scattering easily.
