My specific application, drilling in quartz (7 on the MOH scale.

My specific application, drilling in quartz (7 on the MOH scale, diamond 10) was frustrating. The drill bits are very brittle. I have two broken , but the broken part can be chemically removed. They drill into gems very slowly and require patience and a light touch. I'm looking for a professional diamond drill bit. If anyone knows where to buy this one, please let us all know .

Did not work on cleaning out grout. Wasted much time and NOT a good value.
