![]() ![]() This thread has cleared up for me why everybody hates the things as they have got me out of some tricky/expensive problems in the past. I have never broken one, although I have had to give up on occasion before I risked breaking it. Removed a burred-out drain screw from a mikuni carb. Removed a sheared rocker cover bolt from the head of my old honda.Įxtracted FIVE sheared-off mild steel bolts holding the sprocket onto the cast alloy carrier on my old russian bike.Įxtracted a sheared-off brake nipple from my GPZ500s. ![]() I have used them with good success on several occasions to do the following:Įxtracted a broken off sparkplug thread from the head of my CB125. I even use a hand drill to make the pilot hole for extra control. When the thread finally bites, it will snap like.well, like a tap that someone has just tried to cut a thread with using an electric drill.Įxtracting a sheared bolt using EZ-outs is a slow, painstaking and above all MANUAL job in my book, you can feel if you are putting too much force on BEFORE it breaks. I am not surprised you are all snapping the bloody things if you are drilling them in, what sort of control do you expect to have over the force you are putting on it in a drill? Any decent electric drill would snap one with a quick press of the button, not to mention it not cutting itself a decent thread as it goes in which is critical to how they work.Īll you will do with a drill is ream out the hole bigger than it needs to be then jam a wedge-shaped piece of metal in there which will expand the bolt from the middle and make it even more stuck. Look at the picture below showing (from the top down) A drill bit, a tap and an ez-out. It is a reverse threaded, tapered tap with a square end on it specifically there to fit into a tap holder. Sorry Stink, but I'd never use a tap and die to get a stud or screw out!īut an extractor IS a type of tap. Slowly drill into the hole you have just made.Īs the extractor it wider the further in you go it will eventually grip and try to undo the broken / stuck stud. ![]()
