What drill bit to use to make a keychain from a dead 1.2GHz Athlon?

Title says it all. I am trying to figure out what drill bit to use to drill a hole in a dead 1.2 Athlon. I tried Cobalt bit but, it just slid around. Any help would be great.

carbide works every time i have one if you want it.. lmk

So you have used a carbide bit and it worked on an Athlon chip?You have me wondering now if it was carbide not cobalt that we used. Is there such a bit?

Very small cobalt bit in a drill press would do it!

Maybe Titanium or Zirconium?

carbide will cut most athything.. just go slow... what size ya need.. ??
carbide is better than cobalt..more expensive though

 

[DARTH_MAUL]

not to sure. I just need a small hole big enough for a keychain or necklace size to hang from rear view mirror. I am really wondering now if it was a carbide bit that we used..hmmm is there sich a thing as a cobalt bit. if not then the carbide bit in the drill press we used was a no go

 

[Johnnie]

you prob used cobalt.. was it gold in color.. ??? if so...cobalt..carbide is alot heavier..and more brittle.. got to be very careful drilling with it....

Carbide bits are also know as masonary bits. Usually have 2 carbide cutting flutes soldered on to a steel shank. They look a lot different than hs steel or cobalt "twist" drills. They can cut through masonary or brick, but you often get a rough looking hole. You could clean it up with a carbide end mill, chucked in a milling machine (and you could bevel the edges of the hole at the same time with the right tooling). Problem would be holding the Tbird chip solidly enough to prevent any vibration or chatter, without at the same time crushing the chip. If you want to send it to me I'll play with it and see what I can do.

Ack no one seems to have carbide....:-( Actually the bit was heavy and no it was not gold. Maybe it was carbide we used. Any other suggestions?

i have a solid carbide bit... used to drill tooling steel.. if it was carbide..it would have cut through the cpu...

 

[WebDude]

By the way, how did it die?

 

[Johnnie]

hey webdude.. what do you think..carbide will drill most anything ..right ??

Saw a pic where the pins had been sanded down and a solid copper wire soldered across the nubs on two adjacent sides with a loop at the corner- easy.

Or I'd try grinding a small hole with a rotary burr in a dremel, ceramic is difficult to drill, and brittle.
