How do I change the keyless chuck assembly on a cordless drill

If you are looking to change the keyless chuck to a keyed one, give it up. I cannot get the keyless chuck off my drill and I suspect it has permanent set loctite which would require heating the shaft and chuck. Disassembly would be required to apply enough heat to break the bond. For me I cannot justify time and trouble to disassemble and reassemble the gearbox on the drill. I have found hex or triangular drill bits, hole saws, and countersink tools that will not slip in a keyless chuck but... I still do not like those darn things.

Put drill in reverse grab ahold of the drill Chuck our use a key. A cordless drill you grab the Chuck order the speed button slowly and it will loosen.

Try holding the bit in a vice and gently tap the chuck off of the bit and see it it releases the pressure on the jaws.

It should have a keyless chuck, so put the drill in reverse, hold on to the plastic chuck (just behind where the bit connects to the drill) to precent it from spinning and pull the trigger until the chuck loosens. Replace the bit in the reverse order with the drill in "forward."

I hope this helps! :)

There should be a Screw in side the end of the chuck were u put the drill bit in u will have to undo it back wards its got a left hand thread

This drill has a keyless chuck. Put your bit in the chuck and hold the collar of the chuck while pressing the trigger in the forward position. To undo the chuck do this in reverse. You can also hand tighten the keyless chuck if you prefer. I have a 1/4' adapter that I keep in my drill so I can change bits quickly.

open jaws for large size bit.look in bottom and there will be a screw slot or phillips head screw or possibly an allen head screw.remove this,by possibly turning clockwise. and then chuck up a large allen wrench. try removing the chuck by tapping wrench with hammer. this may be threaded on counterclockwise.have to try both ways.

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

Most chucks have a tolerance the cordless drills where designed for drill bits 1/8 and larger the 3/8 chucks are a little better with the smaller bits .Check your owners manual and see if they have a min requirement listed for the bit size

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.
