To those following i've updated initial post with all compiled info and final results of ROHM SUPRA chuck...........ITS AWESOME!

First post updated with everything in one spot including pictures.

However, gist is as follows

2604-20 with Rohm 871045 Type 136 Supra 10mm

Roughly .005" and valve itself had just a bit under .002" runout. I am stoked!

Thanks for the update. It looks like the chuck you went with goes up to 10mm which is roughly 3/8". If you want effectively a 1/2" chuck you could go with Rohm's 871055 which goes up to 13mm. Enco has a sale with 25% off (code DS531) and free shipping (code FF531) through 11PM ET on 5/31/16. With 25% off you could get the chuck linked below for $60.72. The Enco page says 1/2-20, so I think it's the correct thread.

So is Rohm 871045 a direct screw on?

Yes. Only one down side if you can call it that. There is no reverse thread retaining bolt. But that may only come as a problem drilling in reverse, which is rare and hardly ever with a big bit and a lot of resistance. Locktite and proper torque, and its there to stay.

Thanks! Yeah, i rushed through it and accidentally got the wrong one. Now that i know Supra line holds up to its claims i'll take my time and find the right one as there are quite a few variances. Thanks for the coupon!

My milwaukees don't really wobble bad, but they do not grip the bits well at all. I know my older V28 drill grips like you welded it in the chuck, the M18 non fuel was terrible. I thought maybe upgrading to the fuel version would help. No such luck, as tight as I can get them, they still spin, between a crappy chuck and idiotic manufacturers putting the sizes where you can wear it off in one slip of a bit, well you get the idea.

So how much better does it grip????

I had a Rohm supra on my 18v dewalt in 2008. It would leave huge gouges in the bit it use to grab so hard. If I did it up with 2 hands, it couldn't spin it.

This is only for the FIRST gen Fuel hammer drill, yes?

I thought I read in an earlier post that the second gen (2704) uses a different spindle thread size.

 

[bsaint]

My Makita had a ton of shaft runout from the factory. I threw away the drill. Oh well.

 

[Acuratechva]

I have not done any testing to see if drill bit gets gouged up, can only guess it must be with a cheaper softer metal bit. Definitely something i will keep an eye out for

Correct fits 1st gen drill

2704 uses 9/16″ by something
while 2604 is standard 1/2"-20

2704 is actually the 3rd gen(current model)

All testing was done with 2nd gen 2604 Drill which had just as much runout as 3rd.

and yes 2704 uses 9/16″ by something
while 2604 is standard 1/2"-20

Third gen Fuel hammer drill? Was the first 2504?

I always thought there were only 2 generations.

I dont know enough to argue or agree. Media sources have referred to them as such.

Possibly implying that either standard brushed drill or brushless(but non fuel) were the first generation

EDIT: I've done some googling and you are right. Corrected all my gen this gen that all is now correct.

Yeah it was always my impression that the current 18V FUEL impact driver, impact wrenches and hammer drill were second gen (except the 2763). Signified by a 27 as the beginning of the model. The first gen equivalents had the same last 2 digits (i.e. 04 for the hammer drill) but had 26 as the beginning model numbers.

You could also put the Rohm Extra chuck on the 2604, its a lot shorter but still more reliable than the stock chuck. Since you've noted the 2704 has a different spindle setup, Im not sure what Rohm chucks fit the new one.

I didn't have any issues with my M18 Non-Fuel drill, but when I got a FUEL I had the same issue with bits spinning no matter how hard I tightened it. Swapped the chuck out with a Jacobs from Cripe Distributing and it holds tightly since.

Have not done any texting but feels good just by playing with it.

Thx Fixed it.

Anyone experiment with any chucks?

Re: Milwaukee Drill Chuck Wobble

I just came to deal with it as it is like others said "just a hand drill"....how steady and true are your hands holding it to begin with

Absolutely understand. But just the other day i was drilling out an aluminum caliper bolt to put a heli coil in. Just that little bit of runout/wobble caused the sides of the bit to bite lock up. Very frustrating.

Sadly i cant sell this junk on Cl to save my life(well at least not at this price ha-ha.

Note in the above that most of the self tightening keyless chucks are for clockwise rotation only. The mechanism of of the angled jaws that cause these to grab tighter as they work will cause them to loosen if run counter clock wise. Be aware of this if you have problems running in reverse.

Re: Milwaukee Drill Chuck Wobble

UPDATED 5/24/16 with final resolution.


I've removed most of my emotional dribble and added the final solution to be all in one place.

Original complaint was : So i googled first. Found that it may be common, but there was never a resolution anywhere. Last discussion on google was 2013....my m18 GEN3 CHUCK DRILL WOBBLES LIKE A ZBITCH. Right out of the box.

What started it all. 2704-20 Chuck Wobble. No measurements were taken of exact runout.

After sending in the drill for warranty repair and having same issue unchanged i went to look for an upgrade.

I've concluded that the issue was a garbage chuck with poorly machined teeth and went on to pick up a ROHM Extra, RV only to find that it had incorrect thread pitch. Turns out \Milwaukee has switched to larger ****** spindle from a standard 1/2-20" thread.

Since i already had the chuck and was curious to see the difference, a trip to HD was made for a 1st Gen 2604-20 drill. Chuck went on perfectly but to my surprise issue wasn't resolved. A slight improvement of ~.007 at best. Still something you could see with an unarmed eye.

OEM Milwaukee 2604-20 .033"

VS
Rohm Extra RV .022"

If you keep a close eye you will see iscrewed up a bit and it wasnt zeroed out. I suspect it was more like . 025"

This got me researching and stumbled on to ROHM's catalog which featured a Precision Supra chuck. Figured at this point i had nothing to loose and if this 3rd chuck disappoints i'll bend over and settle for whats there.

Roughly .005" and valve itself had just a bit under .002" runout. I am stoked! So to all the negative nancies that told me its normal and i should deal with it ...**** it! Just kidding


There are lighter Supra chuck variations. This one was close to twice the weight of OEM, but the price point made me make the move. Its the nicest chuck i have ever touched. Sooooooooo smooth its just pure perfection.

I gotta ask, how much did you drop on that Supra chuck?

With all the compromises, ie weight, larger size, and price im not sure I would go to this length. But great info, thanks for updating and taking the time to document.

 

[BFBOB]

Yeah, I have a wobbling chuck on one of my Milwaukee 12V's Don't think I'm going to try to warranty it,tho -- it's a 2nd gen NiCd from oooohh, about 1980, and the wobble only showed up after the second time I dropped off the top of a 6' stepladder.
