[s-cars] Re: broken stud removal tools

[Dean Ferrera]

The 4 pc Left Hand Cobalt bits worked well for me in boring the stud.
After I broke the extractor; they had a tough time with the hardened
steel.  After I broke the second extractor I moved to the Dremel Carbide
Grout removal bits.  I used both sizes.  They ate through the stud
extractors pretty well.  This time I used these carbide bits almost like
a ream until the stud was pretty well gone.  Lastly I used a flat single
flute extractor to back off the remnants of the stud.  It was pretty
amazing; I pulled out almost an entire threaded stud section which was
bored to just about the root of the threads.  

Just a note I broke the stud with the Craftsman stud removal tool.  It's
a great tool, but for something this sensitive I should have bought the
correct sized stud removal tool in the first place.  The Craftsman
single cam style puts too much side load on the stud.  I finished the
job up with the Facom roller style removal socket, which worked
perfectly.

Doesn't NAPA offer reversed (left-handed) drill bits.  NAPA carries
screw
extractor kits - check with them about the contents of the kit. Maybe
you'll get lucky and one of the screw extractor kits will have
left-handed
bits.

I got a cheap set of left-handed drill bits from Harbor Freight. Not
local
to you, but maybe they could FedEx something or maybe someone near a
local
store could FedEx or hand carry a set to you.

>From www.harborfreight.com:

4 PC. LEFT HAND HIGH SPEED STEEL DRILL BIT SET
Remove bolts or studs easily when the head breaks off. Eliminate the
need
to bore out and re-tap the hole. Simply drill a hole in the broken stud,
insert a screw extractor, turn the extractor with a tap wrench and back
them out. Made from high speed steel.
Only for use with reversible drills.
Includes 4 left-handed drill bits: 1/8'', 3/16'', 1/4'', and 3/8''

ITEM 38180-0VGA          $4.99

HTH,
Eric
