Broken Thermo Bolt

[theWeezL]

Ive had some experience trying to get blots out and very little success. first of all the broken part of the bolt is going to be very hard. Harder than the surrounding material. If you slip off and get into the surrounding material your going to make it nearly impossible to get the broken part out.


my best advice is take your time, be very careful about the angle at which you drill. I also recommend you use a very small bit and make a pilot hole first, then work up to larger bits until you have a hole big enough to fit the largest easy out that will still fit into the broken bolt. Go solw and dont put alot of pressure on the drill bit, let it work. Also if yu have some light oil, like 3in1 that gan help remove heat and lubricate the bit so you dont dull it as fast. I also agree on the left hand bits. I got a set of them from Autozone that have worked for me in the past.
