Drill chuck stok in the thigt possition cant get the bit out ; cant make de chuck to open or close

Put your drill into reverse, and hold the chuck. With luck, that will loosen the chuck and the broken bit will fall out.

Most new cordless drills don't have a key(keyless chuck). Put the drill in reverse and hold tight to the chuck barrel, pull trigger and the chuck will open. Opposite to close/tighten Best I can do with info provided

Hold the chuck and run the drill either forward or in reverse until the chuck is fully closed or open then reverse it while holding chuck.

The large black part of the chuck should turn left and right to extend (close) and retract (open) the three chuck teeth that hold the bit in place. Turn the chuck to open it far enough to get your bit fully in the chuck then turn it closed to hold the bit in. When the teeth make contact turn the chuck a bit further to get it tight enough that the bit won't slip. When you get used to it, sometimes it's easier to hold the chuck lightly and turn it by lightly squeezing the trigger to turn the chuck with the drill motor.

If a large enough drill bit is inserted too far so it bottoms in the chuck, the jaws run into the bottomed shank and will not close beyond a certain point due to the interference. If you hold the drill bit out about 1/2 inch from the bottom, the jaws should close on the bit. I assume you have tested the chuck without a bit to verify they can close.

Hi. Try the drill at slow speed without any drill bit in the chuck. Look closely to see if the chuck wobbles off centre whilst holding the drill firmly. If it does then there is a good chance that the chuck is loose from the body. If it seems ok then next close the chuck (tighten it closed) to see if all the 3 jaws are lining up ok and open it again to see if the jaws retract back down the chuck smoothly. (jaws are the small parts inside the chuck that grip the drill bit) If the chuck it seems loose then you can use a long allan key to tighten it up which is inside the chuck. If the jaws do not operate properly then i would suggest taking the drill back to b&q for them to fix, or replace the tool as it should still be under warranty. Good luck

If the chuck is stuck open and you cant "muscle" it closed something is probably jammed up in there and it needs to be replaced. Chucks take a good share of the abuse on power tools and most manufactuers consider them a "common wear item" like brake pads or Tires on your car. A chuck is fairly simple to replace if your drill stuck open and they are commonly replaced on the higher end "Industrial Grade" Power Tools like DeWalt and Milwaukee.
Looking at the Make and Model of your drill it would probably be easiest and most cost effective to just replace the entire drill. If you tried to replace the chuck and found a chuck that will fit your tool it may cost you anywhere from $25 - $40. For Around $40 you can purchase a new drill with a fresh battery.

your must have a keyless chuck. hold the black center part of the chuck and run the drill forward or backward to open or close the chuck.

Well I couldn't find a pix of your drill so I will guess that it is a typical drill. You seem to be asking a very basic question so I will start will all the basic info I can think of.

First you have to know where the power trigger is to make it go.

2nd you have to know where the forward and reverse switch is.

Now with the switch in the forward position squeeze the trigger to make it go. Then gently grab the chuck with your hand while it is going and the center Jaws should close up and come out of the chuck.

Now with the switch in the reverse position squeeze the trigger to make it go. Then gently grab the chuck with your hand while it is going and the cetner Jaws should open up and go into the chuck to a maximum point

Open the jaws enough to put the drill in the jaws then put the switch in the forward position. Put the drill in the chuck, sqeeze the trigger to make it go, and hold the chuck so the jaws close on the drill. All while keeping the drill from falling out of the chuck.

When it closes on the drill and the drill is in straight then hold the chuck as tight as you can while squeezing the trigger to make the jaws close very tightly on the drill. If you have very tender hands you might want to use gloves.

To get the drill out put the switch in reverse, hold the chuck very tightly, and squeeze the trigger to open the jaws off of the drill.

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
