Sorting out some "stuff", I found a packet of 0.091" dia half round drills.
What special use are they for? Similar to gundrills?
Searches on various forums seem to suggest that they act similar to gundrills, but most gundrills are 3/4 round, instead. That would prevent them wandering better than only a half-round solid part.
These are only about 4 thou over half diameter in the solid part. They are 0.049 solid, 0.091 total. Maybe enough, maybe not.
Curious, mostly, no application in mind.
