To take a chuck off of your drill open it up all the way.
Inside there's a screw that you have to take out. It has to be turned clockwise to get it out.
You may need to struggle with it a bit because it's usually really on there tight.
Some folks even use a second drill to loosen it up and that's a really good idea if you have access to one.
Once you get the stubborn little screw out, put an Allen wrench in the spot where the bit would fit in.
If you can't turn it--and you probably won't be able to--then try using a rubber mallet to (gently) hit the arm of the Allen wrench to get it to turn.
Then you should be able to just take it out.
Put the new chuck into the drill.
Add a few twists of the Allen wrench in the opposite direction.
Tighten it up good.
Put the screw back in place and also tighten that up good.
The drill has a lot of vibration and if these aren't tight, it'll cause problems down the road.
Your drill, expertly fitted with your brand new chuck, should now be good to go.

SOURCE: Chuck broke on Skil hammer drill

As long as the new chuck threads onto the old spindle then any chuck will work fine.

1/2 hammer drill and the chuck is broke what do I do to get. New drill or fix


Assuming that the drill is still operating, I suggest that you get a replacement chuck, To remove the old chuck, insert the chuck key in the cogs on the left hand side as you hold the drill facing outwards, then using a hammer tap the chuck key firmly so that the chuck will revolve anti clockwise. Replacing the chuck us the reverse of the above procedure.

How do i replace the jacob chuck on a hilti hammer drill?


Open the jaws of the chuck all the way open. Inside the chuck you will see a slotted screw. Use a large flat head screw driver and remove screw. It will have left handed threads.

After you remove the screw put the end of the chuck in a vise where the 6 flats sides are. Put the drill in low gear and reverse. Hold tight and turn on the drill. This should run the chuck right off the spindle.

How can I remove the chuck of a KR 110 hammer drill. The LH threaded internal screw has been removed but the chuck remains firmly fixed. I want to replace the existing chuck with a Jacob's type keyed...


The chuck is screwed on with RH threads. Lock the shaft and insert your chuck key into one of the key holes. using a plastic or wooden mallet give it a sharp tap in the right direction, this should free it up so that you can remove it. When you reinstall the new chuck us the same method to tighten the new chuck.

Need to change chuck


When you buy a replacement chuck it will have detailed instructions- at least Jacob's brand chucks do. Basically there is a retaining screw inside the chuck that needs to come out first- it may be left-hand threads . Then you put the short end of a 1/4" or larger allen wrench in the chuck and close it tightly. Set the drill on a bench with the chuck off of the bench and strike the allen wrench with a mallet in a counterclockwise direction. Do this several times, then you'll be able to spin the chuck off by hand. Reverse the process to install the new chuck.

Chuck is locked open


you have three jaws in your chuck, one of them will probably have a small burr on it causing it to stick.

try this...

tap the chuck with a small hammer then try to use the chuck key gently in the opposite key hole to the hammer blows. turn chuck though 120degrees and repeat.

if this does not work chucks are fairly universal and easily replaced (i would recommend a keyless jacobs). you can get the old one off by removing the ph2 (phillips) machine screw inside the centre of the chuck... be careful!! this screw is usually soft and counter threaded... when screw removed bash off the chuck with a hammer and cold chisel...

good luck

I have a very old 3/8'' elecric drill, I think it ia a Skil, The key chuck does not work properly and I want to replace it. How do I remove the old chuck?


If it's anything like their other drills, there is a safety screw with left-hand threads inside chuck.

  1. Turn it clockwise until loose.
  2. Then insert the short arm of a 3/8" hex wrench and tighten.
  3. Strike long arm of wrench sharply counter-clockwise and chuck should loosen to unthread from spindle.

Locking ring split on keyless chuck


First you need to shift the tool to the low position, turn the clutch setting to the drill only position. Open the jaws and remove the chuck retaining screw it is LH threads. After all this find a bent handle allen wrench about the size of the chuck capacity and insert the smaller end in chuck and tighten. Put the chuck on a block or wood or workbench with the wrench at about a 30 degree angle so you can hit the wrench counterclockwise. Strike it with a hammer, it might take a couple times but this usually works. Good Luck
