Sould be on Engineeringmadness.org with this one but never mind.
I have been drilling CP Titanium with ease. Easier to drill than stainless steel I can assure you.
People have said that to drill Ti takes quite an effort. Perhaps the alloy type makes a big difference?
I have no alloy to try, only CP.
Have any of you guys drilled Ti.

Dann2 - you haven't been paying attention...
See page 3 and 6 of the Cobalt Oxide Anode thread!
Also this was discussed at length in another thread recently! Not sure where!chemkid - 14-12-2007 at 18:09
Does Engineeringmadness.org even exist?The_Davster - 14-12-2007 at 18:11

I've put holes through some 6Al4V pieces. Used a moderate speed (typical for, say, steel) and an HSS drill, probably not altogether very sharp, with
lube. It took a lot of pressure, much like trying to work with steel spring stock: high yield strength and surface hardness, but still soft enough to
yield to HSS and produce chips, stringy chips at that. (Say, I still have those chips sitting around. I was going to burn them some time.) It's my
recollection that titanium is best done with sharp, very hard cutters: carbide preferred. It follows that coolant and a robust machine are desirable,
especially where production feedrates are concerned.
As far as engineeringmadness is concerned, I would recommend rec.crafts.metalworking for that, and sci.electronics.design for electronics. There are
others, mostly that I don't know of. Often you'll see crossposts on RCM going to sci.engr.joining.welding.

Hello,
Thanks for replies.
I am drilling 3.1mm holes in CP so they are not big and that is perhaps why they appear to be easy to do.
