I'm not familiar with R clips, FWIW.

AKA hairpin clips.

It really calls for a small lathe -- and likely something like a
Taig or Sherline might get the speeds right. And I know that the Taig
has a spindle available for WW series collets, which are commonly
available in metric sizes in 0.1 mm steps.

A lathe would be more appropriate for axial holes. The OP needs radial
holes.
