Have you contacted Johnson Matthey? They supplied me with some very rare rods a few years ago.

I think they where designed for large concrete / stone cutting tools.
I have had some from here years ago , well I say I got them , actually a got one from someone who had bought them from the site.
But then I kicked myself because I remembered he had changed to a 2 part diamond epoxy which worked nearly as well at a lot lower cost.
Thanks for the link though :)
