I would never buy this drill again !
I am a low voltage contractor my tools are my life. I have many Milwaukee tools
and I love them all. however this drill is a no go. Over heats doesn't have the power
the old version had. I tried it with different batteries same result. Milwaukee needs
to revamp this drill.

I want to like this drill so bad but it’s horrible
I can confirm what everyone else is saying with the wobbly chuck. But that’s not my biggest gripe.

All Gen III fuel models I found out have a digital clutch mechanism as opposed to the standard mechanical clutch like the past models. Maybe this feature will be more refined in the future but in the current state it renders the drill useless imo.

This will be my sixth return looking for the right Gen III drill but I think it’s time to look elsewhere. (Mine also has the sticking trigger, and a weird intermittent issue where the drill would get stuck in digital limbo while functioning the trigger

Bought this in the packout combo kit
Bought the fuel hammer drill and impact and both have exceeded my expectations. I put 3/8 and 1/2 inch lags into 5000psi concrete maybe 6 or 8 holes every half hour with no issues. Havent used any ship augers bits in it but wouldn't be shocked if it just chewed them up like the gen 2 did for me.

I would not buy this tool again older model better
I bought this in place of my old beat up 18 Volt drill we had for years with the expectation that with all the improvements it would out perform the older model. Not so. Torque on high is horrible, it bogs down with a 1/2" bit and also on low. When drilling on low it goes way to slow, almost no need for variable speed. I might have bought a lemon. The compact size and the weight is really nice, that's about it. I love the Milwaukee line and have owned nothing but for the last 35 years of being in the construction trade. This is the first real disappointment.

Not this one
Trust me, this specfic model is junk!! Beware!! I bought the “pack-out kit” with this drill and the chuck wobbles. I decided to return it to home depot. Got a new one. The new one wobbled and the trigger worker intermittently!! I returned “the mess” and got my money back!! The first drill was 4 days old. Still shocked!! below is proof of my return

This is your strongest 1/2 inch drill? I was expecting a lot more.I drill 5/8 inch holes through cabinets for water lines in the occasional hole in a 2 x 4 for water lines and this thing stalls out on me constantly.I asked for the strongest 1/2 inch drill that they had and this is what was recommended by the rep. I returned it thinking it was a faulty drill but the new one does the same thing. It gets halfway through the two-by-four and just stops and I have to restart. Practically any dewalt drill will outperform this drill hands down. Too bad I have three grand invested in the Milwaukee stuff.

Weebles should wobble - Chucks shouldn't
I bought a new packout kit with this drill/driver included. When first using the drill, I noticed some wobble of my drill bit. It was an old bit, so I tried several others. It became VERY apparent when I tried using my pocket screw Kreg jig system. The metal sleeve doesn't let the drill walk - the drill/driver itself started wobbling.

I then proceeded back to where I bought it from to exchange for a new tool. The NEW one has the VERY SAME PROBLEM!

Dumbfounded as could be as to how poor the chuck design is, I called customer service who forwarded me on to some tech support type people. The gentleman on the line was extremely professional and kind despite his lack of knowledge of the feedback on this website. He then explained that the tolerance on the tool was 0.012" at 1.00" on a calibrated rod. In other words, if your drill bit is 5 inches long, you could wobble approx 1/16" and the tool is within tolerance. Seriously?

Yes, seriously. Sad, I know. The other sad thing is that the only ones reading this feedback are probably marketing people. And, they're either not talking to the technical people or the technical people aren't listening. Either way, it sounds like you're losing customers FAST.

My old Dewalt drill holds a center just fine and doesn't behave at all like this drill.

DIY and Ice Auger
This product thus far has been great for ice auger use. Drilled 20+ holes in 12" ice on one battery and still had more power left.

Chuck Wobble
I really dislike this drill. I am on my 3rd replacement drill under warranty due to Chuck Wobble. I am going to take this one back as well.

I bought this drill for my ice fishing auger. I have always had a lot of respect for Milwaukee tools until now. I ordered the drill on line, and when I tried it the first time , the trigger hung up on the fwd/rev switch cross bar. I returned it and ordered another one, and it had the same issue. I suspect it is either a design problem or a quality control issue. Otherwise the tool seems well built and plenty of power. I can make it work for now, but I will be sending it back to Milwaukee Tool for warranty repair after the ice fishing season.

BEST ANSWER: Model 2804-20 will not include the battery or charger. If you need the kit, the model will be 2804-22. This model will include the two batteries and the charger.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
