Message	I was helping a friend replace AC compressor earlier today. We managed to round out a bolt, snap off a drill bit inside, snap off another drill bit inside, and still not be able to get the bolt out. We're just trying to drill a hole to use an easy out. Torching it didn't even work. What is your preferred drill bit for this kind of job? Remember that it has to be strong enough to cut through existing bits stuck inside it. ----------------------------------------------------- Never Play Leapfrog With A Unicorn!!!

I don't see what everyone is so worried about anyway. If someone else wants to perform a modification that you believe will destroy the value, cheapen the Z32 or whatever you can't sit on your hands about, wouldn't that make your tastefully-modified, white bread Z32 more rare and valuable? -- BradZ (FL) on December 23, 2007 at 12:19 PM The unicorn gets its revenge... -- Scotts94z32 on September 19, 2006 at 11:12 AM

(n/m) - zellamay 01:42:52 07/30/13 Is there enough room for vise-grips? (n/m) - -Grimm- 14:40:23 07/29/13 Drill-Out extractor, bit built-in, reverse threaded - Ron(Houston) 21:46:16 07/31/13
