Hi fellas.  I have a bit of a conundrum and I hope that one of you can help me.  I am looking for a drill bit size (so I can buy one) for .047 and .032 wire.  I am absolutely lost when it comes to these oddball sizes.  I have never had to buy anything less than 1/16 before.  Any help would be appreciated.  I tried to get the information from McMaster-Carr, but they will not reply to my enquiry.

'Number or Gauge' or metric drills are what you want.

No: 67 is exactly 0.0320" but I suggest No: 66 (0.0330") would be better. Check your wire diameter before purchase. The next sizes are No: 65 which is 0.0350" and No: 64 is 0.0360".

3/64" is 0.0469" which is very likely too small. My experience with hobby shop wire is that it is usually larger than the nominated size. No: 55 (0.0520") is the next size greater than 0.047". For added clearance No: 54 is 0.0550" and No: 53 is 0.0595"

If you can get metric drills, 0.85 mm is 0.0335" and 0.90 mm is 0.0354".

1.25 mm is 0.0492" and 1.3 mm is 0.0512"


Hope that helps

Paul

This is exactly what I am looking for....thank you so much. ;D
