Hilti SDS max problem

    My te75 Hilti SDS max has the chisel but stuck in it. The bit is new, and I just can't get it out, so now I'm stuck using it as a kango. I used to use the rotary side of the drill a lot and would like to Again.
    Any tips how to get the bit out?
    I've tried holding the bit in a vice and pulling but it won't budge

    Give your lad a hard pull to get it out.

    Try spraying wd40 down into the chuck it might free it when you pull back the release part of the chuck
    Did you put any grease on the new bit before putting it in
    Was the new bit a Hilti bit

    WD40 is a waste of time, amateurs thinking WD40 solves everything.

    This might work spray a bit of wd40 (I might be an amateur but hey) in to the chuck place the bit in to a vice pull back the release chuck then give the vice a few belts of a hammer the vibration might release the bit with out damaging the drill. With out the grease the bit might of partial welded itself to the chuck with the heat build up. Worth a shot I'd reckon.

    Ball bearing that locks tool in chuck is possibly stuck. Wd40 and a few blows of a hammer around the chuck should free it. Had similar trouble with SDS Plus chuck. Could be a sign that the chuck is getting worn. Or lack of lubrication.

    Makes a bit more sense than my welded theory alright ,read it somewhere else in internet land. I think it was more to do with cheaper /softer bits deforming in the chuck with heat.
    But like above lubrication and vibration (no bad jokes) should set it free

    GMSA is most likely correct with his diagnosis. I've had a problem before where the ball bearing stuck in causing the bit to fall out when the drill was facing downwards. Regularly spray some 3in1 or similar lubricant (not WD40) into the chuck to keep the ball free.

    Out of genuine interest why not wd40 ?

    Wd40 not designed for wear prevention. It dries off and has no lasting lubrication. A smear of grease or fresh oil on the head of a tool before it goes in the drill is your best bet. Most drills kangoes come with a container of grease nowadays.

    Ah sound I was recommending to use it as a penetrating oil firstly to try and free up what ever is stuck inside the chuck. Then grease the bits for any following work.
