Well I was cruising the web and found these Bosch replacement keyless chucks and took a gamble on them. Bought two for less then the cost of a craptastic replacement Milwaukee OEM chuck. Turns out these are German made ROHMs, 1-13mm (1/16-1/2"), with excellent engagement, metal sleeve, and cheap!

BUT... didnt fit. The oem had a longer sleeve, the Bosch must incorporate a collar into the drill body?

Found a piece of steel tube laying around that fit perfectly! Unreal. I could not have ordered a better piece.
Perfect ID and OD clearances. Chamfered the body side for a conical fit, other side was squared off. Super clean, 100% functional.

Check it out-

Because the Milwaukee drill itself is superior in just about everyway. They make the best drill IMO. The only issue is the chucks which are sub par. Otherwise, they have higher torque, they're more compact, and with better runtime. Not to mention the ENDLESS options in the battery platform. Bosch is great, don't get me wrong, but Milwaukee has like triple the amount of tools available.

Because I found these for pennies and wanted to upgrade my existing chucks...

----

One of my drills was super easy, unscrewed the inside bolt, broke the chuck loose, cut the metal ring and deburred it, installed. 10 mins?

The other, the exact same model (M12 FUEL) the gearbox is slipping and I can break the chuck loose from the drill body? No idea how to overcome this?

Use my never fail method. Take the largest 1/2" drive hex bit that the chuck will accept. Insert impact wrench in 1/2 drive end and knock it right off. Slipping gear trains are no obstacle. I assume you tried the hex key and hammer already. 3/8 drive probably works, too but I do not own one.

The only thing that allows the chuck to break loose is the gearbox. There is no way to hold the gearbox/motor like on a angle grinder.

Ive tried everything, put it in reverse, forward, high, low, screw/drill mode, 6PT method (only spun the gears),nothing seems to work?

Luckily I just did the exact same thing to the exact same model and know that im rotating the right way, ha.

Unless I am missing something I think I will have to warranty this drill when it makes sense, then replace the chuck on that one.

Nice, I'd really like to upgrade my Gen II M18 Fuel chuck. I haven't really had issues with my m12 Fuel's chuck, but the m18 drives me up the wall half the time I use it.

Check Amazon, there is always a few nice chucks floating around it seems.

I have been on a keyless chuck kick lately, and found some nice stuff out there.

https://www.garagejournal.com/forum/showthread.php?t=359134

Look up Rohm, Llambrich, LFA/Reichel, Spain made Jacobs (same as Llambrich), also Yukiwa Seico.

My models (Both M18/M12 FUELs 2015?) take 1/2" x20 UNF thread...

They changed the gen 2 to a different thread, presumably the onekey too. No idea about the gen 2 Fuel m12.

**** chuck you got there Tarmy :)

Bmack37- I thought I heard that, totally LAME on Milwaukees part to change what is likely the most common replacement thread available.

Is it some Metric spec or just wonky?

ps that Rohm looks a lot like mine but with a added knurled collar.

Concur the chucks on Milwaukee's M18 drills do not impress, I attempted to swap out a chuck on a hammer drill to no avail for the exact same reason, bits were slipping in hammer mode, never did get it off and wound up getting rid of that drill.

Hmmm...it appears that rohm 893352 works as well. Wonder what the difference is between 802490 vs 893352?

I'm not sure, I've been waiting on someone else to do it before I bother with pulling my chuck off. I'm glad some other guys posted about it because I was about to get a new chuck and just add to the number of guys buying a new chuck and not being able to use it on the 2407-20.

Luckily for me, I don't use it that often(I normally use a smaller/lighter drill unless I need the power) because that chuck is the worst of all my Milwaukee drills.

I put a jacobs dewalt chuck on my Milwaulkee. Works great. For all the hype Milwaulkee makes about their tools, their chucks are the biggest POS I've ever had to deal with.

What model is your drill and what Jacobs chuck did you use

Or you know, just buy a drill with a chuck that actually grabs? I've used quick release chucks where you barely have to snug them down with just your hand and they don't slip. Milwaukee has no excuse for using such trash chucks when lesser drills can do better.

Wow, that severely limits your options eh? Plus I bet runout on a hex shank is higher than a standard bit.

Honestly tho, my M12 chucks wernt terrible, they just wernt great. When you tighten down a quality chuck you know its not coming out.

That is kind of a glaring issue.

No doubt, I'm not defending Milwaukee, they seriously dropped the ball on that one. But for me, drilling heavy metal everyday, it was worth buying the Milwaukee then dropping it off at my service center and paying $40 for a top notch new chuck. Total that's $145 for a top of the line drill and chuck.
