FAQ. Why my extra-coarse diamond is so slow?

Sometimes, abrasive A has zero cutting performance on steel B, or causes blade chipping, or extreme stone dishing, or glazing, or balding... We often cannot explain the fact of specific incompatibility, we just accept it. Grit value is a major factor affecting cutting performance. The intuition tells "coarser" means "faster" (larger particles remove more metal). However, it does not work for extra-coarse grits. In the coarse grit range up to the optimal...
