Carbide Cutting Tooling with High Pressure Oil Holes. Need Suggestions on Plugging.
(OP)
I am looking for options on plugging high pressure coolant feed hole in a solid carbide drills / cutting tools etc.
The coolant hole diameters vary based on tool diameter, Tried brazing, epoxy and expandable plugs, some of the processes work, but stain the finished tools or change the diameter by a few microns. Any suggestions will be greatly appreciated.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
