Use a CBN tool instead?

No, it's metal bonded. I was more concerned about the diamond dissolving
in the steel. Presumably it should be kept cool, so a slowish speed and
coolant - suds or perhaps water.
I thought about using graphite as a lubricant - would that do anything?
Any other ideas?

The main diamond attrition process is chemical and
temperature sensitive. It's no longer a problem at hand honing
surface speeds. Run the wheel at the lowest surface speed that
removes metal an acceptable rate.
Darex drill sharpeners use a single low speed diamond
wheel for sharpening both carbide and HSS drills.

The following is quoted from a email sent by Greg Brookes of Eternal Tools.
It refers to diamond drills, but I daresay the same priciples apply to your
tool.
"Remember that like all diamond drills pressure must remain light and have
plenty of water circulating in and around the work."
