Has anyone seen the Poltava vitrified CBN stones?

I was just browsing around on the Hapstone.eu site and saw Poltava vitrified diamond/CBN stones for only 79.99 euro. So I figured I'd ask if anyone used them or knows anything about it. I always thought Vitrified bonded CBN Stones were expensive. Or did I get that wrong? I mean, I'd buy 'em if they're any good. Anyone know anything about them?

As far as I know, those seem to be older models of the PDT (Poltava) Premium line. The latest ceramic-bonded products should be from the Premium Silver series, which incorporate metallic components. These models offer higher wear resistance. I have a 650 grit one, and the grinding experience is very smooth and quite fast.

I don't know if it's an older or newer model (honestly their model naming schemes are a bit confusing), but I have a PDT "Premium Vitrified" 6x1" stone, 550gr 40/28um. It's great. I use it as my finishing stone when I use a guided system.

They are of the new line of PDT stones. Blank size 4mm thick
They are not the Premium Silver Vitrified, that are the more expensive ones. These are in an category of their own. Made for bevel formation and re-profiling. Only made in 3 grit sizes. 225, 285 and 550

That’s good to know. Thank you.

Yeah, I find it a bit confusing as well. Good to know you’re happy with them. I like their metallic CBN stones, but haven’t tried any other PDT stones.
