    Bits Sticking in my Impact Driver

    Not too long ago I replaced my ageing Makita LXT impact driver with a new one. The new one is much more powerful and has several fastening modes. But, I never stuck a bit in the old one (10 years old) and have stuck bits three times in my new one (6-8 months old). End up needing to use visegrips and a hammer to remove the bits.

    Is this common? Do I need higher quality bits now?


    Thanks

    I've seen this on some bits. I think they may be a tad undersize, or perhaps too soft, and can twist enough to jam. If Bradley's suggestion doesn't work, I'd try a bit rated for use with an impact tool, all the major brands sell them.

    My newest LXT driver was like that too. I just kept a T25 (the most used bit) in it, and used the old one for changing bits. The newer one finally loosened up after using it for a while. If it was the only one I had, I would have returned it.

    Use impact rated bits

    This... Impact rated bits allow a little flex, while non-impact rated bits must dissipate the energy by deforming in some manner such as twisting or rounding over. Same principle as using impact sockets.

    I've been experiencing this same issue, with an older Makita impact driver I have. Wasn't sure if it is the driver, or the bits that are causing the problem. It seems to mostly happen with a drill bit with a countersink, kind of aggravating!!

    Drill bit in an impact driver? I consider that a fire-able offense.

    I've this happen plenty of times with impact drivers of different makes. If you tap the end of the stuck bit abruptly on a hard surface, many times the shock of the impact can loosen the driver bit enough so that it comes out easily. If it's happening more than every once and a while, I'd consider sending it in under warranty to replace that part.
    That's just like, your opinion, man.

    I've got to ask, why?

    I've had that happen in my Dewalt Impact driver. I found if I reversed the driver the bit came out.

    Thanks for the help. I ran out last night and picked up some Bosch impact rated bits. I drove a 3" deck screw into a 4x several times and the bit did not stick. Hopefully problem solved.

    BTW - come to think of it I didn't use my old Makita impact driver much since it was too powerful and hard to control. My new one has 4-torque levels and a few auto modes and I use this thing all the time.

    I had a bit stick in a dewalt driver but it was one that I sort of ground to fit and I didn't do a very good job. When I got the driver, I had some hex shank bits that were just straight hex with tiny dimples for some sort of chuck. I ground the recess into them and one stuck. I got rid of those bits and haven't had a problem since.
