For anyone who's not familiar with Glacern, they're an American manufacturer of very high quality vises, toolholders, etc. A few months ago, when I first learned of them, I bought one of their "premium" vises, and it is an absolute work of art - dead flat, square and level, and zero lift. I just bought one of their R8 keyless drill chucks, and it is every bit as good. Their quality is just phenomenal! Highly recommended!
