Red Layout Dye

The purpose of the red layout dye is to make sure the grinding wheel is getting the blade completely sharp. Apply the red dye to the gullet, face, and back of the tooth of the blade to take the guess work of blade sharpening. When the CBN grinding wheel hits the gullet of the blade and leaves behind red dye, the grinding wheel is not matching the profile of the blade. To fix this, adjustments need to be made to the depths and angle of the grinding wheel.
