1. Please keep the speed within 800-1000 per minute, low drill pressure and increased use of water lubrication will extend drill bit life.
2. And please keep adding water when the diamond drill bits are working on the glass or ceramics.
3. Not for use on Concrete. Water or Coolant is required when drilling, or the diamond core drill will burn.
4. The general rule is the smaller the diameter of your drill bit, the faster drill speed you can use. The harder your material, the slower drill speed you should use.
5. They can drill slate marble, but only for a few holes, because diamond would wear off easily and shorten its work time.

Kindly Note: Please allow 1-2mm errors due to manual measurement, thank you for your understanding!
