Thanks Stephen for your kind words about our service and support.  Great to hear you love the small diamond drill bits too! Thanks for your continued custom.

Thanks for your feedback David, we really appreciate it.  The drill bits are coated with diamond grit and will wear out over time.  To preserve the life of the drill bits make sure to use plenty of cold water as a lubricant, drill on a slow speed and use very little pressure. You might like to try the small diamond core drills instead.
