Need CBN grinding tools

[distshooter]

I am searching for CBN (cubic boron nitride) grinding pins as used in die making. I'm in the bay area and would prefer something local. I'm interested in small diameter 3/16 - 1/4, and also shapes such as inverted cones.
This is for AR bolt carrier mods.

Thanks for any help in advance.
