Here looking at what's inside the Milwaukee 2504 second generation M12 fuel 1/2 inch hammer drill. Foley Disick the gearbox a nice All Steel 13 gear unit . .

Thanks for the level of detail. I'll be running the video backwards (if I could). This afternoon I opened up my drill and pulled the motor off the gearbox. There went all those little gears onto my garage floor. I'll set the parts on my shop bench tomorrow, and with help from you video, get everything back together.

The technology engineered and produced in this Milwaukee M12 Hammer Drill is beyond phenomenal. This drill belongs in the Smithsonian Institute.

I have two of these, plus an 18V and two 28v versions. A man cannot have too many drills I say. Nice to see the milwaukee has 'more' to it inside, than the equivalent B&D. Now I know where my extra money went. My original 28v is now 11 years old and still going strong on original brushes. Milwaukee spare parts (motors etc.) have made in Germany stamped on them, so they may be put together in china, but all the important parts are German made.

Very interesting - really appreciate your experience / technical knowledge sharing and your priceless comments.

awesome- my 2408-20 is intermittently dead. I have to pull out/reinsert battery many many times to get it working for a few minutes. I was going to take it apart but I can find no tear downs. I see the clip and the screws for clam shell---so I will give it a go. This video helped me tremendously to know how it comes apart and how to deal with clip. thank you

Chinese ownership of the Milwaukee brand. Milwaukee Tools is ultimately owned by Techtronic Industries headquartered in Hong Kong.

Did you know Techtronic makes Ryobi, Craftsman, Hoover, Homelite and Rigid among others?

I just purchased the M12 fuel hammer drill and impact kit in October 2021, and I noticed they are both made in Mexico now. I'm very pleased about this for 1, it's not made in China anymore, and 2, Mexico's a lot closer to made in America. I would much rather see our tools come from somewhere other than China.

Very interesting tear downs. Just discovered this channel. Coming from AvE.

Just bought this drill it looks pretty nice judging by the internals. Although lots of powdered metal steel parts, from AvE’s tear downs tho he even saw that the $700 HILITI drill had a plastic gearbox housing and powdered metal gears...

Dewalt and Milwaukee target the same customers, I don’t feel Milwaukee is better than dewalt I have fuel gen 3 tools that have had little issues from purchase but watching you tear down of the dewalt extreme 12v and the Milwaukee m12 they both are engendered great and well made I own the m12 also haven’t used it as much good video!

[procrastinator]

Those loose gearbox screws, I opened mine to fine all four had completely backed out almost half way! I can also confirm the stupid air intake sucks in everything and FILLS the case with crap. Hoping a gen 3 version comes along soon and solves this!

Very good teardown and explanation, you're starting to remind me of AvE 👍🏽

after watching this video, I went to home depot and grabed one for $129 CND with one battery and charger, thanks for your work.

[philjohnson]

Awesome teardown and explanation. That circuit board looks like trouble if the tool gets wet.

[zachproctor]

Great video, man. I really enjoyed nerding-out with you.

[TheSebastian]

Even after 2yrs this tear-down is awesome.

[BrianSu]

Fantastic video. Not a single dislike. I have the exact same drill but my chuck looks different from yours. Mine has the knurled pattern all way round and no smooth parallel breaks like yours does. Thanks for the video as I had been wondering what was inside the unit.

[scottc]

Superb video! Due to some rather unfortunate idiocy on my part, I definitely needed gear information you provided. Thank you

[nullptr]

thx for the video, mine started to not stop when torque was reached in 1st gear but works great in 2nd.. service seems terrible in my country and they don't aknowledge this as an issue because it "runs ok" on tests

[davidperry]

My gen 3 m12 fuel hammer drill is made in Mexico. Regular clean and lubes cab definitely extend tool life.

Great video. We love your tear downs. You are like a walking encyclopedia.
Curious what is your background?
