Review on Meccion Extractor Ceramics Porcelain Mandrels by Jason Dahlkemper

Highly Recommended! I was very pleased with the performance of this drill press. There are many diamond crowns in all price ranges. I made a small jig to make sure the hole is perpendicular to the post. I went through the counter like clockwork. Probably 1 minute drilling. Buy a good quality diamond saw and you will be amazed at how easily they can do impossible jobs.
