once bolt is broken we need to extract it, this is the tool we need it to extract broken bolt
first thing is drilling, so there is drill bit
drilling should be in centre, so there is drill guide
this is the extractor to hammer in broken bolt
i hold it this extractor with this extractor nut
all information about drill bit drill guide ,adapter size is printed on tool
there is one broken bolt in this steel plate
so i want to use drill guide first, all information is written on bushing
if you have 3/8 broken bolt use this bushing using 1/8 drill bit
main purpose is drilling should be in the center
if i will drill without guide bit will start wobbling here and there
when i will use bushing it will drill in center making pilot hole
i need to over-size this hole
now it is oversized hole
i will inset extractor and lightly hammer it
now i will slide nut into the extractor
turn a broken bolt with wrench or plier
broken bolt is out
