Tip: The following three crucial elements when drilling will prevent the diamond grit from wearing off or burning away, will prevent the drill bit from snapping (too much pressure applied), prevent your material from cracking, and extend the life of your drill bits.

• Use with plenty of cold water (if drilling in a container, change the water when it turns cloudy)
  
• Use on a slow speed of 5,000RPM
