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.[highlight #73D216][highlight #73D216][/highlight][/highlight]
