Sharpening of diamond drills for flat glass
The active part of a diamond drills, the one that will allow to pierce the glass is made of diamond grains. These diamond grains are embedded in a metal alloy which aims to gradually release the diamond surface of the diamond forest so as to pierce the glass.
By piercing the glass the upper part of the diamond will break little by little.
This bond must wear at the same speed as the diamond. If it wears too quickly there is too much diamond on the surface and the forest will wear out very quickly and there is a risk that the drilling is done with scales. If it wears less quickly than the diamond particles there will not be enough diamond grains on the surface and the forest will not pierce the glass properly. In this last case it is necessary to sharpen the forest in order to use the binder and to make appear again grains of diamond on the surface. This is done using synthetic stones, usually aluminum oxide.
But the need to sharpen core drills should be rare, at least for the best diamond drills. Indeed the suppliers who are in this case use bonds that wear at the same speed as the diamond and therefore without the need for sharpening.
Sharpening is a real problem in the case of automatic drills.
