Re: Those Cheap Diamond Inserts

That's true, but I did run across a reference (Stefan Gotteswinter video
maybe) to an actual diamond attached to a tool.  There are also coatings
that are called diamond, although most are actually DLC "diamond like
coatings."

I've watched an optical lathe turn a Germanium lens for a military vehicle thermal imager with a clear single crystal diamond bit with the geometry of brazed carbide. It may have been synthetic, the laser diodes I had for the inter-satellite communications project were mounted on thin sheets of artificial diamond on a gold-plated copper heatsink. Diamond is an excellent conductor of heat but an electrical insulator.
