    I broke a tap in my output shaft. I'm installing my SLE from Driveshaft super store and it calls for drilling and taping. Well I was doing my last turn before I backed it out and it broke off just below flush. How do I get it out? /forums/images/graemlins/1zhelp.gif

    my experience with tap and dye sets is, you don't get a tap out. you could try to drill a smaller hole in the end and use an EZ out, but the taps i have messed with are usually to hard to drill. you best shot would probably be to take it to a machine shop

    I have a set of tap extractors in tool box.Will go tomorrow and see if theres a part # or such on them for you.They basically have four hardened pins that slide into recesses of tap with a sliding collar to reinforce them and usually will back them out.If you know a really good welder you might be able to get them to weld a nut onto tap{weld through center hole of nut}and back it out.LOL /forums/images/graemlins/thumb.gif

    NICE JOB!!!
    first off what size was the tap, how many flutes on it, do you think you bottomed it out and was it a cheapy?
    1-You need to blow the hole out as best as you can, get all the chips out.
    2-sometimes you can take a smaller tap and tap on the flutes as to unscrew it.
    3-how big is the part, might need to put it in a lathe and carbide it out.

    If it is a pretty big tap, you could try welding on a smaller bolt...oter than that, I don't think you will be able to drill it out with a hand drill to use an EZ-OUT...

    I know how that goes... ^^^^ They are fairly brittle so its not too hard but its time consuming.
