Keyless Chick will not Release - Hitachi DS18DMR

This drill, Hitachi DS18DMR, will not release the bit in the keyless chuck. I just finished using a spade bit and had no problems. When attempting to free/release the bit the chuck will not budge. It almost rips the skin off your hands.

Any help would be appreciated, Dave

    The bit may have wedged in the jaws.

    Have you tried to use a channel lock pliers to hold the chuck?

    Or stick it in a vise?

It's best not to use the drill power and your hand to try and release. Or tighten for that matter.

Set the drill down, and try using both hands on the clutch.

If that don't work, try using vise-grips or channel locks.

If that don't work, whip out of the WD-40 and let soak and then try again.

Cannot get the chuck to release the bit it is a dewalt and yes I am in reverse


On some of the DeWalt drills I have owned with keyless chucks, the chuck has a locking mechanism.
You have to grip the chuck and slide the outer sleeve forward to release the lock, then you can tighten or loosen the chuck.

How do you work the keyless chuck on the 6.5 amp 3/8" rear handle pro drill?


Most drills with the keyless chuck work this way. Put the drill into reverse. Grasp the chuck with your left hand, and then pull the switch slowly. This should release the chuck. If your drill has no reverse, then grasp the chuck again with your left hand and hold the drill with your right hand. Turn the chuck with your left hand quickly, this should release the drill as well.

I have a drill bit stuck in my drill and I can not get it out of the chuck How can it be released from the chuck that I can change to an other drill bit.


By stuck do you mean that you can not release the chuck? if so then you can use 2 channel lock pliers to grip the chuck and the base to break it free. i have done the same on a keyed chuck and a keyless chuck .

Keyless chuck is stuck with bit inside I can't turn it counter clockwise to unlock I have a Makita 6349d drill


Try two channel lock pliers.
Hold the bit close the the base with one.
Take the other (cloth comes in handy here to prevent marring) and turn the chuck counter clockwise to release.

Alternative (little WD40 on the chuck)
One channel lock plier hold the chuck and put the drill in reverse.
The WD40 should allow the chuck to release easier.

Good luck!
