I checked at the mall today. My gouging .005 diamond burnisher was from Bruce Diamond, purchased from Mitchell Tool while they were going out of business. It works great on glass with a nosecone, but does give some problems when I use it on brass. (No I do not use the same bits for both, I have separate sets.)

I guess that their setup is a little different than Antares on the faceting of the bits.

When you finally understand it completely... it changes.
