Yes, I did. I used a milling machine and a #52 .0635 drill bit if I remember correctly. A 1/16 bit could also be used .0625.
I do suggest you buy a quality drill bit. Titanium is similar to stainless when drilling. I use light weight oil to keep the piece cool while drilling and be generous. If it heats up and work hardens it becomes almost impossible to drill.
Here’s a video that might help a little.

A few years back after receiving the mill, I got tired of dull bits and failures. I invested in 2 set’s of good USA made drill bits. Not cheap but you will not be disappointed in the way they drill. Very sharp and they stay sharp. You can also buy the individual bits separate if you only need a certain size. This is the exact sets I have.
Good luck!
