Wow!! I'd look at EDM, but I don't know if the electrodes go that small.

the easy part is ordering the drills!!

 

.1mm = .004"

 

is this a mill or lathe op, if lathe, can you buy canulated stock?

we had a job very similar to these dims and we were able to purchase cannulated stock.

 

the issue we had with drilling such a small hole was the initial peck, the drill point would grab and snap. also you'll need a high speed spindle

for the SFM required by a drill that small.

My titex catalogue shows a solid carbide micro presision drill at Ø.1mm but it's flute length is only .5mm. i think you might find it difficult to locate a drill with such a small dia. vs. depth. you have a 15-1 ratio on dia. vs. depth and that's a whole lotta depth.

High speed spindle:-

Investigate the available drill lengths. Probably may need 3 drills 1=0.5deep 2=1.0deep 3=1.5deep.

 

Sure you can get sucess.Try!

Kyocera for drills. i'm looking at one i have its .13mm x 2.31mm loc. carbide circuit board drill. i'm sure they make a .1mm with at least 2mm loc. i've drilled 440c with these 2mm deep at 35000 rpm at .5 ipm pecking at .001 per peck

with a .1 mm drl at 35000 you only get 36sfm. you need all the rmp you can get!!!!

Careful with the air turbine spindles, the runout may be more than the drill can take. The best air turbine I could find for a similarly crazy job was dicy for a 0.3mm drill. 0.005 runout on 0.1mm drill is way too much.
