What d i need to cut jade on a lathe? How would you drill a hole? Water? Lubricants? Drill type?

Diamond tools.

I believe jade is the second hardest mineral (after diamond).

I made a few small pieces years ago. Used water as lubricant with diamond drills. Very difficult to work with. Best I came up with was cutting strips on a slow speed diamond saw and gluing to a tube like many do now with abalone. Need lots of patience and many bits.

Hmmm .... pretty sure the second hardest naturally occurring mineral was corundum (sapphire/ruby). It's also known by it's more common trade name of Aluminum Oxide, used for abrasives.

Strange, that I can pick up a 25# bag of black sapphire from Harbor Freight for around 35 bucks ...


Have you guys tried using a carbide glass cutting bit for drilling jade?

Interesting thread and good information on drilling a hard substance. However, jgrden is really sharp today. Must have had razor soup for lunch.
