I've bought a new 3/8 keyless chuck for my B&D drill and even before I
can find out that the new one is the wrong type and doesn't fit I'm stuck,
since I can't get the old one off the drill (old one doesn't tighten
very well and works loose).

I've removed the screw from the chuck, where one inserts the drill bit,
but the chuck is still very tight etc.

I've looked in my DIY books and skill books but no help ..

Thank you,
Neil

IIRC correctly when I changed the knackered chuck on my black and decker
cordless (some time ago now) I removed the screw, inserted a rod of some
sort in the key hole, and whacked it with a hammer, left hand thread I
guess. Good luck.

Having removed the central locking screw from the chuck, get a large
allen key and insert into the chuck and tighten chuck, use a hammer to
hit the end of the allen key so as to rotate the chuck off the nose of
the drill, if it is a geared multo speed drill then put it to low
speed. The chuck needs to rotate anticlock wise (looked at from the
open end of the chuck)

As others have said, it is screwed on with a reverse thread screw.

I normally put an allen key in the chuck, tighten up, grab hold, put drill
in reverse, lowest gear & squeeze trigger. If it was really stuck, or a
mains drill (prolly take my hand off!) I'd clamp the allen key in a vice.

All depends whether your drill's got enough torque to free the chuck.

No, chucks have a conventional thread. The locking screw is left hand
thread.

doh! you're right, sorry.

mine doesnt have a locking screw (spindle has a hex socket to accept driver
bits, so a screw would be a PITA), and whilst going through the mental
motions I somehow got things twisted around....

Once upon a time, you had to remove chucks regularly to fit attachments.
And the recommended way was to insert the chuck key and hit it with a
hammer...

Huh? A drill normally rotates clockwise (viewed from the rear) so if the
bit snatches, such as when breaking through when drilling metal, it
would tend to undo the chuck if it were a LH thread. I bet it's the
locking screw that's a southpaw...hang on....just been out to the garage
(any excuse to get out of the house with this heat :-) )...yep, the
locking screw is LH thread on my old B&D Quattro.

Yup, acknowledged that mistake in response to previous post. (don't ya just

Yes, but OP has got a *keyless* chuck!

The nearest equivalent would be to clamp the short end of an Allen key in
the chuck, and then to give the long end a sharp tap with a hammer (as has
already been suggested by others earlier in the thread).

No, chucks are standard RH thread or they would unscrew when putting
screws in or when the drill jams.

You're right. The first part is still valid:

....hit with a mallet or rubber hammer *in the correct direction*.

My mis-recollection was of some idiot (not me!) belting hell out
of a chuck key with a steel hammer, trying to unscrew the chuck
the wrong direction.

No - a standard chuck has a right hand thread since basic drills go
clockwise. Reversing drills have a locking screw which is left hand thread.

Thanks for all the advice. Managed to do it. Retaining screw was LH
threaded and chuck was a normal RH thread.

Ahaaa, it all comes back to me now: the idiot in question was
holding the drill handle with the chuck facing away from him and
trying to unscrew it by turning the chuck anti-clockwise *from his
point-of-view* - which is actually tightening it, of course.

Good question! I had assumed that he was replacing like with like - but I
suppose that he *could* have been replacing a keyed chuck with a keyless
one. Perhaps he will tell us?
