Thought that title would thin the herd!
If you know about making stuff like Jewellery or ornaments or whatever from crystals or stones, I need advise about drilling a fairly large hole in a fairly large piece of Hematite.
The Hematite is a 45mm diameter ball. The purpose is to make it into a gear knob for my car.
The hole will be 12mm in diameter and 25mm deep.
I found this drill bit which I plan to use in a pillar drill at slow speed with continuous liquid cooling.
I still have to work out how to clamp the thing and have no idea if it will just shatter or explode so I thought Id see if anyone here can help. Cheers
