HowToMakeCPUKeychain

I have a Pentium 'classic' 166 and I wish to turn it into a keychain. I've heard stories about how it is almost impossible to drill a hole through the die so I was wondering if anyone has some ideas on how to get a hole in my Pentium. And no I don't have a diamond drill at my disposal =)

the pins are too short to do that..plus the pins are really soft

Use a small grinder, like Dremel MotoTool, and a green bit (silicon carbide). It will cut ceramic tile- should work on a CPU.

I think even that might crack the brittle ceramic case. The only things that can reliably do the job would be Silicon Carbide, or diamond grinders like mouspotato says.

You can have a go though.

i just soldered a wire onto an old p90

voila! instant keyring

ok, there is quite a lot of solder on there, but it works

Silicon Carbide bits are about $2-3 tops. If you don't have a grinder (I got mine from Sears- about $60US w/ 50 or so bits), an electric drill will work. It will take a lot longer, though. My grinder turns 15,000rpm. Average drill motor- 2000-2500rpm.

Silicon Carbide bits are green stones on a steel shaft. Get 1/8" or 3/16" ball bit on a 1/8" shank (will fit Dremel, Sears, Rotozip, etc.). Too much pressure will break the stone right off the shank, be gentle (especially if you use a drill).

I am a machinist for a tooling manufacturer. I cut mostly metals. Steel, iron or aluminum 99% of the time. I did machine a ceramic vat recently (pump housing for molten aluminum). We had diamond cutters made to machine it. Synthetic diamond- still pretty expensive, I'm sure, but I never see the bill. Next to diamond, CBN (Cubic Boron Nitride) is next hardest. Still too expensive. Carbide is next hardest- readily available/cheap. I personally have used it to cut holes in ceramic tile when installing towel rack in my bathroom. I don't have any doubt it will cut CPU's ceramic. Mail your old chips to me and I will be happy to do it for you. I don't have one to try it on. At least, not until I buy replacement for the POS I am on right now!

carbide bits for ceramic/glass workbut the trick is to keep water on the chip so that it dosen't get hot and crack or flake pieces off arround where you are drilling.

I am making my 1.1ghz athlon that i partially crushed into a keychain too, i'm glad this post was started, i would have just drilled away!

make a key chian out of the p 75 then sell it for 15

what about using an oil based lubercant spray to keep it form getting to hot
