I finally lost the chuck key to a Makita 907d cordless drill.
The chuck has never been very good at holding bits, so rather
than buy a new key I'm thinking to get a new, keyless chuck.

Does anybody have a favorite, or suggestions to avoid? It's
a normal 3/8-24 right hand female thread, so that's easy. The
original chuck is Jacobs, are there better brands out there?

I put a Jacobs that looks like this one on my battery drill several
years ago. I don't use it a lot but it works really well for me. I like
it better than the keyless chuck that came on the Dewalt 3/8 inch corded
drill. It clicks down when you tighten it. Price is similar to what I
paid (~$20) over 5 years ago at a local Menards store. They don't seem
to have it anymore...

I have a bunch of chucks (mostly imports), but its surprising to hear
you didn't have like the Jacob's. Usually genuine Jacob's chucks are
quite good. I wonder if Makita licensed the name.

I did notice the chuck seemed to lack lubrication, so for the moment

Tangent... I've always been a fan of Milwaukee for drills and recip
saws. Particularly recip saws. However the quite durable steel shell
keyless chucks that came on the Milwaukee cordless drills I have owned
are hard to grip, and always seemed to need the help of some slip joint
pliers to tighten well, and by extension to loosen. As as Joe Pi would
say, "to unloosen."

I had decided not to get more Milwaukee Cordless for my shop due to the
price of batteries and went to Bauer. Bauer is okay for very occasional
use, but for even regularly occasional use I wasn't as happy as I hoped.
The batteries are cheaper, and the batteries are decent with bigger
batteries performing better than smaller batteries just like other
brands. I just wasn't thrilled over all. After my dad passed I gave
all my Bauer stuff to my son and took over my dad's DeWalt cordless
stuff. One thing I noticed about the DeWalt keyless chucks is its very
easy to get a good grip, and I can reef down on them easily by hand.
Further the drill only turns a short distance before coming up on a firm
stop to reef against when tightening or unloosening a chuck by hand.

To give an idea. I use my one remaining Milwaukee cordless almost
exclusively for tapping 1/4-20 blind holes. I tightened it with slip
joint pliers and never take the tap out. I have a bottoming tap to
finish the last few threads in a DeWalt cordless right next to it, and I
was able to tighten by hand enough that the clutch slips when I hit the
bottom of the hole, but the tap doesn't. The DeWalt plastic shell
keyless chuck looks and feels cheap, but it works really well. I have
three DeWalt cordless drills now. Very useful.

Further afield. I was replacing all the locks on my dad's commercial
property yesterday. Well, my mom's property now I guess. I took my
DeWalt cordless stuff with me and used the cordless angler grinder (I
bought that one) with the 8AH batteries I bought. I continued to be
impressed with how well it performs for a high power cordless tool with
those batteries. Several double cylinder deadbolts had to be cut off.
I sliced right through them in order to cut through the screws I didn't
know how to expose without the key. Big batteries continue to be worth
the price. More longevity for light work, and more current for heavy
work.

including a recip and a circular saw , but no batteries . Got 2 3.6 A/Hr
Ni-MH batteries on eBay and I'm good to go for around the house . Shop
drill is a 20V also from a yard sale . Came with a charger and one good
battery ... so I bought 2 more bigger ones .

I normally tighten key chucks with just one of the three holes but...
when slipping problems occur I'll go around and tighten the bit with
all three holes which usually stops it from slipping. Maybe you
already know this but a lot of people don't. Chuck instructions often
tell you to use all three holes but who reads instructions😄️

That chuck I suggested cost 2/3rds the price of the drill I put it on.
The keyless chuck it replaced was miserable junk so it was a huge
improvement in my case...

Point taken. I usually check bad reviews but didn't this time. the

Still, in-person transactions aren't foolproof, at least when I'm the
fool. Went to a local Ace store and asked for a chuck key to fit a
3/8" Jacobs chuck with a 15/64ths (0.234") pilot. The pilot's right,
fits just fine. but the pinion gear is too big.

It's a nice bike ride to return it and I don't think they'll give me
much pushback if i want to exchange it for the right part, but that
was a one star deal too.

--------------------------
Is the K number of the key stamped in tiny letters on the chuck?

It's marked SM4G61, with capacity in millimeters and inches. It
also has the spindle thread stamped on it. There's no K number
visible.

If you find one with the right gear but too small a pilot you could sleeve
it with hobby store brass tubing, stretched to almost fit and pressed on.

I don't think it'll be a problem to get the right key. I just wasn't
paying enough attention. In fact, "hobby store brass tubing" will be considerably harder to find, at least around here.

It would have been smarter to take the chuck with me.

This was usually when they tried to buy a chuck that fit named kind of
drill. There may have been wrong-item-shipped problems.

The key comment is that the new chucks are imprecisely made, and so
the chuck cannot grip firmly no matter what you do.

Llambrich makes very good chucks. Their JK Industrial line seems most suitable. About USD 200.

.<https://llambrichusa.com/keyless-chucks/>


R÷hm is also very good.


These hand-tightening chucks will all open if rotated in reverse. Does
this matter?

Still, in-person transactions aren't foolproof, at least when I'm the

Yeah, chuck keys have two parameters, not just one.

Interesting that the page is footnoted "Quality made in Spain"
They do look nice, but rather an overkill for a hand drill.

Röhm is also very good.

Again, 1-star reviews are not encouraging, prompt breakage

These hand-tightening chucks will all open if rotated in reverse. Does
this matter?

Usually, no. In some cases yes. Best to avoid, I think.

Still, in-person transactions aren't foolproof, at least when I'm the

The table makes me scratch my head. The key I have which seems to fit
is a 15/64" pilot with 11 teeth on a 1/2" pinion, from a 1/4" Makita drill.
Not in the table, far as I can tell.

The key I mistakenly bought has a 15/64" pilot with 10 teeth on a
roughly 0.665" pinion. 30825, but with a D suffix.

Looks like maybe I need a "gotcha" key. I'll take the chuck with me
when trying to exchange the key I bought by mistake.

20V batteries over time. Some of my dad's stuff had adapters so it was compatible with current 20V batteries. I ran across a couple older
DeWalt cordless drills on a shelf in the old hardware store when I was
swapping locks. There were different, so I don't know if adapters are available for them, but I'm going to find out.

Thanks for the tip. The price seems surprisingly low. Added to my list >>>>>if things needed to make a free shipping order.

Bob, I'd read the one-star reviews first.

Point taken. I usually check bad reviews but didn't this time. the
"wrong thread" complaints are quite surprising.

This was usually when they tried to buy a chuck that fit named kind of
drill. There may have been wrong-item-shipped problems.

The key comment is that the new chucks are imprecisely made, and so
the chuck cannot grip firmly no matter what you do.

Llambrich makes very good chucks. Their JK Industrial line seems most
suitable. About USD 200.

.<https://llambrichusa.com/keyless-chucks/>

Interesting that the page is footnoted "Quality made in Spain"
They do look nice, but rather an overkill for a hand drill.

R÷hm is also very good.

Again, 1-star reviews are not encouraging, prompt breakage

R÷hm is not a good as Llambrich , but both are far better than what
you currently have.

These hand-tightening chucks will all open if rotated in reverse. Does
this matter?

Usually, no. In some cases yes. Best to avoid, I think.

Keyed chucks are also cheaper.

.<https://llambrichusa.com/keyed-chucks/> Look at type CY. Drill
Chuck Keyed Steel 3/8 in 3/8-24. About USD 100.

.<https://www.amazon.com/Drill-Chuck-Keyed-Steel-8-24/dp/B0086AIMI8>

Still, in-person transactions aren't foolproof, at least when I'm the >>>fool. Went to a local Ace store and asked for a chuck key to fit a
3/8" Jacobs chuck with a 15/64ths (0.234") pilot. The pilot's right,
fits just fine. but the pinion gear is too big.

Yeah, chuck keys have two parameters, not just one.

.<http://www.jacobschuck.com/uploads/202206/14/220614010822483.pdf>

The table makes me scratch my head. The key I have which seems to fit
is a 15/64" pilot with 11 teeth on a 1/2" pinion, from a 1/4" Makita drill. >Not in the table, far as I can tell.

The key I mistakenly bought has a 15/64" pilot with 10 teeth on a
roughly 0.665" pinion. 30825, but with a D suffix.

Not everybody follows Jacobs, even when selling "Jacobs chucks".
Patents ran out a generation ago, and the name became generic as well.

Looks like maybe I need a "gotcha" key. I'll take the chuck with me
when trying to exchange the key I bought by mistake.

Bringing the chuck is the best way.

Joe
