Some chucks get dirt, grime, and other foreign stuff in them or they rust internally and get stuck. If it's too tight to get loose by hand you may have to use some WD40 or Liquid Wrench and a channel lock pliers or vice grips to hold it tight enough to get it loose. If that doesn't work you may be looking at cutting the chuck off and replacing it.

How to remove keyless chuck

open the chuck jaws right up
down the center of the chuck you will see either a philips screw head or a hex head for allen key
hold the shaft at the base of the chuck to stop it from turning and undo the screw in the chuck in a right hand direction ( it is a left hand thread) when you have that out , still holding the shaft turn the chuck in the left hand direction ( normal thread ) and screw the chuck off
to assist in undoing the chuck do it up so that the jaws come out a bit
place something between the 3 jaws to act as a lever or use an allen key in the chuck done it tight and use that as a lever to undo the chuck
the secret is the lh thread screw in side the chuck which stops it from undoing when the drill is in reverse

Cannot release tool from Dremel 300

I had a similar problem with a router, the best way to do it is to get a clamp, a strong metal c clamp, not too big but big enough to fit chuck into, line one side of clamp up with button and the other on the chuck. tighten the clamp as tight as you possibly can so it presses and holds the button in, and does not slip. Then use a wrench or whatever tool you use to undo the chuck. if this does not work, try spraying some WD40 on and leave to work for a few minutes.

Cant remove chuck from a dwd 520

That one looks tricky! If the jaws on the chuck work lock an allen socket in the jaws and impact it of right hand with an impact wrench. This could damage the gears however if it's really tight. Another option is cutting half the chuck off in a chop saw just above the spindle and welding a nut on and impacting it off that way. The heat from the chop saw and welding will help loosen the chuck.
Good luck with that one!

Can not get bit out of dewalt drill DW727 VSR

these drill are a "grip and rip" style chuck, you might have to place the chuck in a vise to get it undone. Though it shouldn't be that tough. I have never gotten a chuck so tight that I could not undo it.

Can't tighten or loosen the "keyless chuck" inorder to put in a bit

What you need to do is get a piece of strong strapping, on a stick like a jar opener, or a vice, or some way of "Grabbing" the chuck, other than you hand, even using the inner edge of a door frame and "Grip" the Chuck, Now with a nice fresh battery installed, put it in "Reverse" and holding the chuck tight operate the unit and it should undo itself.

How do you replace the chuck on a Bosch 650 RE

while holding the drill like a gun, hold the lock button REALLY tight and pull the black part to the right really hard. this will unlock the chuck and if you keep twisting the black part to the right it will loosen it enough so that you can remove it

Never have used a keyless chuck b4- need to change bit, how do I do this? thanks

hi this should be reletively easy hold the end black bit with the sivler bit holde coming out not the black bit next to the yellow case on drill you hold the black part thats at end of drill by where the bit goes into not the black bit near the trigger hope i explain this ok.
Hold this bit tight then put drill in reverse then press trigger a couple of times it might be tight but shouldnt be that tight it wont undo.
1 put in reverse
2 hold black plastic piece near where drill bit goes into
3 press trigger few times
4 this should undo it allowing you to put a bit in
make sure its in reverse else you will just tighten it up more let me know if you need further assistance ok
