Use a sharp metric tap and if you're cutting plastic use a lubricating solution of 50% dish washing liquid 50% water.  Go slow and back the tap out frequently to clear the chips.

Having solved the electrical irritation in the Diablo, I proceeded to changing the sticky exterior door handles (same problem as Ferraris) with some nicer CF laminated ones from MACarbon.
 
After getting the first one inserted, though, I found a problem. The door handles are plastic. Molded into them are threaded metal inserts which take a 10mm bolt to secure them to the door when installed. When Lambo or their supplier molded the replacements, they got a lot of plastic into the inserts. I can see the threads and a little metal, but their diameter has shrunk way too much to get the original bolts into.
 
I tried scraping the insides with a sharp right angle tool to "clean" out the plastic, but the plastic is quite hard. I'm agraid to get more aggressive as I don't want to damage the underlying threads.
 
I suppose I could get a metric tap/die set and do it that way, but I'm still concerned about cross-threading the existing insert, or worse, breaking it loose in the plastic so it just spins, ruining the expensive part.
 
Any other ideas? I've contacted MACarbon but I don't think it was their fault - I think they got them this way.
 
Thanks!
