Chuck problem chuck will not open

If it is a reversible drill there is almost certainly a left-handed thread screw or allen bolt through the centre of the chuck into the drill shaft and this must be removed before the chuck can be removed.

If it is a keyed chuck select low gear if there is one, fit the chuck key and then strike it sharply with a hammer to jar the chuck in an anti-clockwise direction. Usually it takes only a couple of blows before the chuck is loosened.

Keyless chucks are more problematic. I hold them in a vice and use the drill in reverse which has proved fairly successful, though sometimes the chuck is only fit for scrap afterwards.

Lots of the keyed chucks can be taken apart for cleaning and lubricating if necessary.

inside the chuck you will see a screw, remove the screw and chuck . A small punch with minimum forced with a small hammer to move the chuck dogs toward the end on the chuck . The chuck was opened to far and is a mechanical bind ..

Open the chuck wide open. In the center is a retaining screw, they usually have left hand threads. Remove the screw. Take an allen wrench1/4" to 3/8" in size and fasten the short side tightly in the chuck. The chucks are usually right hand thread, so take a small hammer and strike the allen wrench to turn the chuck to the left to loosen it. Once you have the chuck off, verify the thread size of the drill motor shaft, then go to McMaster-Carr and choose the one you need.

Hello, W/D here.

To remove your chuck, open the jaws of the chuck fully, but don't open them so tight that they lock in the open position. Remove the screw inside the chuck. Spray the inside of the chuck with penetrating oil. Tap around the edge of the chuck, while pulling it away from the motor.
It should come right off, with a little effort.

Best regards, --W/D--

the chuck is broken inside if clicking. Ace and True Value stores sell chuck replacements

if chuck is wide open ,look down inside there should be an allen screw or bolt at the bottom of the chuck it should undo anti clocwise and the chuck comes off

this how to get a chuck off a drill.look inside the chuck for a screw. it will be a left handed screw.once you get the screw out put the chuck in a vice . you will need to squeeze it very tight. then put the drill in reverse and pull the trigger.if i wont come off you will need to hit the chuck with a hammer while you are holding the trigger. if you have a bit stuck in the chuck and cant get it out put the chuck in the vice and hit it very hard with a hammer until the chuck falls apart.i work on drills every day ,this is the only way we have found that works

this 2 chuck are 3/8 jaw opening,double sleeve u can hold the chuck will opening it at the sametime.the sinlge sleeve u have to runs the drill while running slow rev/for to remove the bit etc.

1. Turn the screw clockwise to take it out.
2. Then you needs 3/8 allen key & insert the short side of the allen key & tighten the chuck.
3. hold the drill at the edge of the table & wack the allen key
counter clockwise & do it again as needed.
4. dewalt keyless chuck will fit but you might add a washer to insure the chuck is not rubbing the clutch collar.
5. putting it back together the other way.
