The chuck on my 14.4v Makita combi is driving me mad. Its the black plastic
covered one with a front ring that turns to lock it.
When in 'hammer' mode it constantly starts to come open.
Any suggestions for a decent replacement?
I think a keyed chuck is the only option. I changed the chuck on my
Bosch just before christmas for one of these:
is undoubtedly a better chuck than the original, but it does
occasionally come loose - the bloke at the tool shop said to not bother
with a keyless chuck, as they all eventually start coming loose, but I
thought he was talking bollocks, but he wasnt.
Screwfix do chucks now, though a limited few, on the site above there
are lots of options, just make sure you know the thread size on your
I bought a new cordless with a hand chuck and the first job I had for
it was a stepped drill. Once I'd finished using it I couldn't get the
bit out (and I can normally undo any bottle / jar with my hands).
I took it back to the shop (decent high street tool shop not shed) and
offered them the task. The first bloke looked at me like 'noob' and
the started on it as if he was going to undo it easily, he couldn't.
They then passed it along the chain till it got to the gorilla and
even he gave up. It ended up in their vice with some Stilsons and me
walking away with a new key chuck fitted. ;-)
I think I still have one (cheapo) cordless with a hand chuck and I
think it always undoes when in hammer mode.
All the best ..

I have never found the two handed counter rotating ones that
satisfactory. The single handed Rohm ratchet action chuck on my combi
however is superb - grips like a limpet and never comes undone. I don't
think that the latest model Makitas however have been as good.
Autolock chuck on my bosch blue drill good, autolock chucks on my
bosch blue combi and the swap-in chuck on my corded sds - both superb.
The latter two make a ratcheting sound as you tighten them - 3 or 4
clicks and they hold bits that never slip, but release as easily as
Interesting. Up to now I've used exclusively my old mains keyed-chuck
drill, but as I've been doing more jobs since buying my own house I'd
decided to back it up with a cheapish cordless. Often it's handy to have
two different bits on-stream at once (eg shank hole and pilot hole),
plus for simple tasks I guess it'd be quicker to just pick up the
cordless than to start reeling out extension leads etc.
Unfortunately all cheap cordless drills seem to have keyless chucks.
Just got a box set of 3 "Special Offer" from Arco Makita 14.4. £150
1 normal drill driver
1 drill, driver and hammer
and 1 "Nut runner"
The but runner way Ebayed leaving enough cash for a better chuck.
If you can get one of the earlier Makita ones (Off the 9.6v series) then
they work well.
Dunno what they've done with the newer versions though. Mine undoes too!
Back to ARCO for a replacement I reckon
Popped into my mates hire shop this morning with the offending Makita..
TMH; "This chuck keeps undoing when on hammer".
HSM; "Yeah, they all do that".
10 mins & £25 later a new metal chuck which works a treat. Chalk & cheese.
Since the drill was a freebie I musn't grumble.
