0.006 bore on a 0.125 Lead plate

[Tatoz]

This one is a tough one and I hope it can rise a good discussion.
We need to make 0.006 holes on a 0.125 Antimony Lead plate, we've achieved good results with 0.01 drills on 0.1 SS plates but we still have to try now with this smaller diameter on this not so common material.
Thanks to all takers of this challenging thread.

How many holes need to be made? Since the T/D ratio
is more than 20 conventional drilling may not be possible.
Try your job in deep hole drilling EDM. 0.006 to 0.125 is quite possible in this machine.I assume antimony lead is a good electrical conductor. Best of luck.

Laser driling or pulse EBM is also an option if you have access to the equip.
