Dewalt 18v Battery Hammer Drill Dcd950 Dc925 Logo

Jaws won't tighten or loosen to hold a bit

I have a brand new DCD950 dewalt cordless drill, 18v battery. I used a larger diameter bit to drill holes into a couple of wood posts. After this project, I could not get the jaws to release the bit. Finally got it loose using some grips to hold the drill steady. Now that piece is out, the nose will not rotate to tighten or loosen the jaws that hold the bit! Is there any steps I might take to try to remedy this without having to send in for service? I am needing it for simple drilling tasks now!

Hmmm some times the counterclockwise screw that attaches the chuck to the drill come forward and that is how then it stucks the 3 parts that fix a drill to a chuck. Check if this screw come forward. If yes then destroy it and replace it... We destroy it by using a drill smaller than it (usually it is 5mm so we use 4mm bit and of course a CARBIDE one because even cobalt ones can not drill a hardened bolt)

SOURCE: Can't remove bits

I had this problem on my De Walt DW912- I simply couldnt turn the keyless chuck to remove the screwdriver bit and there was no obvious reason why.
I placed the unit on a solid surface so that the chuck/ drill bit was pointing vertical. I then used a mallet and a metal chisel to gently tap each of the 3 chuck jaws back into the chuck body. It worked!
Turned out that there was the absolute tiny amout of corrosion between the jaws, and the chuck and my tapping had just broken the siezure. I now remember that it started to rain slightly last time I used it.
Some spray release agent or perhaps WD40 would probably have done the same job but I wouldnt have believed so little corrosion could have done this so didnt realise this was the problem.

Hi, soak the chuck in crc overnight then put the drill in low speed and reverse. Hold the chuck by hand or with multi grips and pull the trigger. Hope this helps, regards Phil.

Why does my chuck keep loosening

First check whether you have the correct transmission setting for the bit you are using. This may affect the range over which the chuck operates and how it locks onto the bit. A conventional small-diameter drill bit may not work with a hammer drill setting. If the setting is correct, then either your hands aren't as strong as they used to be and you're not getting the chuck tight, or the chuck is worn and no longer has enough friction to hold.

Try this diagnostic: when you put a bit in, use a fine-tip felt marker to draw a line from the chuck collar (the part you turn to tighten or loosen) to the chuck baseplate. If the bit comes loose, check to see if the collar is still lined up at the same place relative to the baseplate. If it is, the chuck pieces are slipping inside; perhaps the transmission setting is incorrect for the bit chosen. If the collar has worked loose (the marks didn't stay lined up), the threading on the collar or the parts it engages could be worn.

How to change bits

The drill uses a cordless chuck (part bits go into) you will need to hold the outside ring of the chuck and spin it to loosen the jaws on the bit. Then spin the chuck the opposite way to tighten

THE CHUCK WON'T TURN WITH THE MOTOR RUNNING. YOU CAN HOLD IT IN YOUR HAND AND FEEL IT CLICKING AND HEAR IT WHAT COULD BE WRONG WITH IT?

The DCD950 drill has a chuck that does not require the reverse-threaded lock screw. It is put on with lok-tite and a good deal of torque. It is hard to remove without the Dewalt vice tool to hold it but not impossible. Some can be removed by tightening the chuck in a vice and, using the drill handle for leverage, apply steady, even, strong pressure until it breaks free. Using this method usually bends the part of the chuck in the vice making it useless. Another reason for the chuck not turning when the motor is turning is a broken transmission. If the chuck works properly in tightening down and releasing bits, your problem may be in the transmission. If you go to http://www.ereplacementparts.com/ and search for your model number you can look at a breakdown of your drill and what you're looking at to replace the transmission.

How do I take a bit out?

It is a keyless chuck. Put the drill in reverse (chuck should spin to the left when viewed from the back) and hold the main body area of the chuck with your hand while slowly running the drill. The chuck will open (unless it is broke) and release the bit. You do the opposite (slowing running the drill in forward) for tightening a bit in the chuck.

How can i remove the chuck from my cordless dewalt power drill

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--
