16D or 20X .05" Dia Drill

[crazy^millman]

Hello I have project where we need to drill this into the Aluminum part. I have gone through a dozen tool catalogs and looked on a few website with no luck. Anyone got a source for a drill like this? I found a Titex 12D 1.2mm that I think I can may work with pecking the drill, but would prefer the correct drill on this $250K part.

 

Thanks in advance for any help.

I can't say I've done a hole @ that diameter but I have used Mitsubishi's 15x MWS internal coolant drill line and it worked like a champ (hole size was .300"). I've used a lot of their drills in 7050,7075, 2024 and 15-5ph ss. They all work great. They do have drills down to 1mm in diameter and lots of 20x+ drills.

2nd vote for mitsubishi. They have a 1.25mm drill that is 20X.

Next choice would be gundrill. I used Sterling brand recently that was a .0625 dia 25X deep. Slow, but did the job nicely.

Kyocera makes excellent tools. We primarily use their 0.003-0.040 drills but they have something in the range you are looking for, I believe. They also have a custom tool order form for custom drills. Might not be ideal for your current job (not sure about the lead time) but for future work.

Ive had good experience with the Mitsubishis.  Walter also makes some really good small, deep hole drills.  One thing about Walter is their help with feeds and speeds.  I used to wor at a shop where we did a lot of inconnel, we had to drill a .062 hole about an inch deep, we got the Walter and use their recomended F&S and it was spot on, never broke one.

That is perfect. Thanks I have passed that on to our customer for next go around. Went old school with a #55 Aircraft drill and Stub drill. Drill .15 deep with the stub. Then come back with the aircraft drill with the spindle slow then ramp up rpm inside the hole and peck .005 not coming out of the whole till depth and then slow the spindle down come out of the hole and go to the next one. Thankfully only 2 holes we need to worry about.

 

 

Here is a link to their PDF. Page 29 had what I could use. If we can get it I will use if not I will go with the above to get the parts done that are behind schedule.

Here is another link to a PDF. Page 7 the 1.3 mm x 20D would have worked. +/.01 on the hole.

I've had good luck using Precision / Dormer drills (in aluminum.) Have a few in front of me now that are 1.5mm 80D. Did it exactly like you described, only the fun part was that it was on a 55 degree angled surface

Thanks I have their catalogs, but they prove hard to get on the West Coast.
