- A friend bid on three broken Milwaukee SDS drills, and won all of them!
They all appear dead, let's take them apart see if we can diagnose the problem and hopefully repair them.

BTW ... I find fluxing and soldering both board and new part always has best results.
Thanks for the tip 👍
Your buddy is lucky he has you for repairing the units he bids on and you fixed two out of three unit. He has a spare unit for spare parts for the other two. Good work mate.👍👍
Thanks 👍
I find a large chisel tip works well to heat and remove the mosfets and to install the new ones. I also dab some solder paste on the pads sit the mosfets on and sit the chisel tip on top, legs first then big pad.
If you feel like digging the resin goup out of the controler on number 3 there may be a fuse resistor, there are in recip saws and high impact wrenchs.
I had been thinking of possibly doing a re-visit on the drill. I haven't had time to do any repair videos the last week as had the body off the wifes landrover. Replaced both turbos still having issues...
@@BuyitFixit lol, I try to avoid big car fixes these days
@@MrTorch8 I'm the same, but needs must as they say..
@@BuyitFixit the gen 1 csx recip saws have an almost identical stator and they have a 22ohm (off the top of my head) fuse resistor on the control board. I'd hazard a guess the drill does to.
Great detail on highly skilled electronic fixes.
Would love to see similar fixes on Makita contractor tools (ie: SDS MAX corded, 7 1/4in circular saw, sawsall)
Thanks, the main reason they are all pretty much Milwaukee is because I was buying them for myself. I've done a Bosch grinder and reciprocating saw, and someone recently asked me to look at a Dewalt 4 way charger (which I'm sure will be in a video at some point).
Loving the Milwaukee fixes. Keep em' coming!
Thanks!
Great work! I have 2 Bosch drills to make into 1 good one, this has motivated me to get on with it! 👍😁
Nice one. Good luck with your repair!
I just fixed my milwaukee chpxi thanks to you.
I can't describe my happiness,
I wish you all the best
My milwaukee broke down after just mby 20 - 30 holes
it was brand new
One of mosfets was blown
Really glad to hear. Well done! And glad the video was useful to you! All the best.
Do you think the problem stems from insufficient cooling of those mosfets or under-rated for the task at hand?
The SDS drills when used as a power chisel is a high duration task. Not too kind on those mosfets
I think possibly if the drill jams up and people are keep trying to make it go to get the drill bit out, that would put strain on them and cause them to blow. I'm not 100% though.
Great fix on 2, a shame about the 3rd one being unservicable... you can't win them all I guess, fixing central heating PCB control boards would be a great one as they are expensive to replace and normaly only the caps, resistors, diodes and dry joints are the failure points due to vibration.
Thanks, yes the main IC is programmed and unfortunately you can't buy them as it's a part TI only supplies under a NDA. Regarding the boiler boards, I know a couple of engineers who service boilers and I could get a supply of broken boards, the problem is I have no means to test them. We also have no gas in our area only oil boilers.
@@BuyitFixit ah ok, not really an option then, never mind, I have bought a tend T35 vacuum non working on the back of your videos to have a go myself. I'm an engineer by trade but left the in depth electronics behind for more cnc related items, 3 phase motors, servo motors and drives a while ago. Watching your videos has made me want to look at it again in depth, so thanks for that, it is appreciated Mick
Good job mate & 2 out of 3 is good going 👍
Thanks 👍
Great work, Milwaukee will be giving you a full time job soon as you seem to know the faults better than the company. Great job keep it coming 😎
Thanks!
Fantastic content! I look forward to more!
Thank you. Much appreciated.
What is the part number of those mosfets? i think I might have missed that.
IRFLS-3034-7PPbF
What part numbers are those mosfets ? Cheers keep up videos awesome, I'm guessing from aliexpress I'm in Australia so bit quicker for shipping just need mosfet numbers
Thanks! The mosfets are IRLS3034-7P but I think it has been replaced with IRLS3034TRL7PP which I ordered and got the parts labelled IRLS3034-7P.
@@BuyitFixit much appreciated found some keep up Milwaukee videos n others your channel gonna grow very quickly I think I'm recommending to all
@@waynetaylor2784 Thank you Wayne!
Love the videos ive been trying and failing to fix a new model milwaukee grinder, think its the control chip thats gone. All covered in potting compound which is a pain 😪 just pissed off the replacment electronics are just under the cost of a new one!!! And the rest of its like new, becuase it was not registored no warranty i can claim im at a loss what to do next
I have a couple I've looked at. A 9" I think and the smaller standard side. The larger the main ic is blown and it's a custom part. The smaller one I could possibly have fixed as it was one of the hall effect sensors had worn through due to debris in the stator but I thought it was going to be too much trouble and I already have 3 of them. They don't seen very repairable unfortunately.
2 out of 3 ain’t bad.
Yes meatloaf said the same thing 😂😂😂
Update on my mission with filling the cylinder.
Firstly Milwaukee wont reply on correct psi. So we assume 130.
Tyre and scuba shops will not fill as there is no data on cylinder.
I tried a friend's air rifle pump and a shadler valve adaptor with a standard pump. Neither worked for me. I believe issue is that the valve pin in the cylinder need pushing in to add air. Neither connector I used had that. Any suggestions would help.
Hi Stu, I had someone else say similar about the valve and explained that in the description.
Merhaba tebrikler türkçe alt yazı eklermisiniz
UA-cam'un farklı diller için otomatik olarak altyazı eklediğini sanıyordum. İncelediğim bir konu değil.
hi I have the same drill, can you give me some indication sometimes when drilling it makeing some noise like the gear is not connected, then sometimes its ok? any idea what's up with it, or is it the gearbox had its time? thanks
From what you said it sounds more like a mechanical problem. I think when I looked on the Milwaukee site you could buy gears and parts separately so it may still be worth repairing.
Milwaukees Controller PCB-on-Stator design is nonsense. Bare Mosfets zero cooling and exposed to the elements. Also makes the electronics more complex.
Most other brands have one big potted controller with an aluminium case for heat dissipation tucked in the housing somewhere away from the already heat producing motor.
Good point. It does have a fairly large aluminium block where the board screws on to, but I didn't think about the motor itself also producing heat when it is under load.
Liquid nitrogen will get that rubber off
Thanks for that👍I'm not sure how readily available liquid nitrogen is in the UK. Even dry ice isn't that common. I managed to remove it with some heat from the rework station and picking at it, it does get it off eventually albeit a bit time consuming.
Another thing to try is the pipe freeze cans.@@BuyitFixit
Good idea👍, I actually have some freezer spray. Used to use it for diagnosing certain electronic faults caused by heat back in the day.
#everypinmatters lol
*if you like I could send you some flux...Maybe you've heard of it*
I normally use flux on a lot of things. Can't remember if I used it on this video?
