- Rotary Hammer Drill Restoration Video
I found this hammer drill from japan recycle shop 18$. It doesn't work because of the armature doesn't move. After the restoration, this hammer drill works very well.

The Ingersoll Rand 114GQC Air Hammer th-cam.com/users/postUgkxqqoaX03nrziKwF7Bjjcc71YzLEleMvOS was just the tool I needed. I Use it to remove stuck bolts. If held at the right angle you can cut slightly into the bolt. Then turn the air hammer to where it will hammer the stuck bolt to unspin the bolt. Given a little practice it works great. This air hammer gives you the control needed to get the job done right. Very powerful yet still does not seem to have as much vibration as other guns I have used. One of the best I have gotten my hands on.
Witam.Super remonty wiertarek,szlifierek,wkretarek i innych urzadzen,perfekcja,prawdziwy majstersztyk,dobre rece czynia cuda,dokladnosc,rzetelnosc.
Close up camera work is fantastic.
View is never obstructed-fantastic.
Sped up time on screw removals is fantastic.
These are the reasons why your videos are so darn good.
Fantastic restoration, could I please ask my dad recently passed away , and left me his tools, he left me a similar drill, but the chisel function doesn't go up and down, only spins around. Could this be an easy fix or is it completely broken, really appreciate any help thank you
Fantastic, as always! It does my heart good to see these old tools being brought back to life!
Oh, really!! I am glad to see your comment.

Lol loved the big hammer what I like about this site is it not too long and not too short ( the Goldilocks thing ) very interesting to watch thank you 🇬🇧
Great restoration - I didn't believe you would be able to make that electric motor work again. 👍👍👍
Thank you 🙏🙏🙏
Amazing restoration as always. Greetings from Greece. 👍
The bigger the problem the bigger the hammer. :D nice job on the restore - I love watching these vids.

Incredible Work I Subscribed. 👍👍👍👍
Excellent ! Greetings from Southport UK
I use a vice grip pliers to hold bolts, washers, and nuts to the wire wheel. Saves fifty-two pick-up from the wheel launching these parts! Nice job.
Thank you for sharing 👍
Excellent work!
This man works fast!!!
clean and great job again nice job bro
Hi, I can not get enough of this video. :) Can you provide more details on your's, power cable to circular spring to brush connection? Around what does springy circular thing connect ? Only detail visible is air holes and copper shining.
Meus parabéns. Ótimo trabalho
Money saving talent right there. Very nice sir!
this is AWESOME!
Very great job.
Next time just re-varnish your armature, and stator windings, that's what the copper wires were coated in originally. The epoxy mix melts under heavy use, and makes a sticky mess, and if some gets on the commutator ruins the carbon brushes.
cierto solo barnizar y meter al horno unos minutos ...
Perfect work. Nice finish!
Gratulation for you! Professional skill!
Thank you 🙏🙏🙏
Invest in an insulation tester...
So you can properly verify field windings, armatures & comms...🇬🇧👍
cierto nesecita una morsa electrica para comprobar la calidad del aislamiento electrico del motor universal
Watching your videos is giving me the idea of doing similar to some tools that a broken. It's not like I'm going to break them trying to fix it since it's already a dead tool 😂
I'm glad this video help you!
Me encanta todo lo que arreglas...👍
After this kind of work this machine should be much more expensive than a newone ! Congrad.
As always a mind blowing restoration, but I have a couple of questions. The epoxy one has already been asked, but also why didn’t you use any filler for the worst of the pitting? Was it because of the levels of vibration the drill will go through? I know you’ll have a good reasons and asking the questions is in no way a criticism. As always compulsory viewing, thank you for posting.
Very good restoration 👍👍👍. May I borrow it? I need to break some concrete in the backyard LOL

Great Restoration. I have the exact same tool. Have followed your restorations step by step and got mine working again. The only issue I am having is I'm getting a leak of transmission fluid at tool holder. Do you know if its easily replaced? Is it threaded?
Show... serviço muito bem feito
🇧🇷🇧🇷🇧🇷😎🇧🇷🇧🇷🇧🇷

Hi gear show 👋👋👋very good restoration drill 👍👍👍 I watch your channel with admiration 🤝🤝🤝
Hi Кошмар Кошмар 👋👋👋Thank you so much 🤝🤝🤝
Good job buddy
Dang, you did a great job on that. I liked how you got the rotor out and cleaned it up. Sweet.
Thank you 🙏🙏🙏
Τέλειο το κομπρεσέρ .
Great restoration your chenel is awesome like
Thank you 🙏🙏🙏
BELLÍSIMA
i think you still need sandplast chamber to safe your polishing time and will give better results
Good job
You do the best restorations! Can u do a gas powered concrete cut off saw( husqvarna/partner, makita/dolmar, hilti, stihl , etc)? Ive fixed and resold 24 , still have 2 great saws Hilti dsh600x w the pump and blade brake, and a restored ( personally) makita 7311 that was non running for $100. Runs great now thank God
Superb 👏🇱🇰💯
Good work 😍😍💣💣💣
Thank you 🙏🙏🙏
Pardon my friend 😗😗😗
great video as useal.
Beautiful! I like 12:00, and the bearing pullers (both inner and outer) particularly. I hope I could one of this and restore one day.
Where did you buy these pullers? Thanks.
Hello I have a similar but older makita without clutch, from the 80s, the engine housing is square instead of round. I can't identify the model missing the plate. I wonder if there are online makita forums, I haven't found any
Came out very well, nice job, it's useful again! Was going to praise you on pressing in new bearings instead of hammering then you pressed a bearing in partially with you vice (acceptable), but seat it by pressing on the inner race with a socket there by defeating the entire procedure. Also why spray lubricant on the cap screw heads, it doesn't reach the threads which need the lubricant to unscrew, and unless they are seated in a metal housing rather than plastic lubricant is of no use what so ever. Overall nice not overdone.
Серьёзный аппарат!
The bigger hammer was the hit of the show lol
Just earned a sub
in 16:48 i was like: NOW! NOOOW! USE IT! USE IIIIIT!!!!!
Maybe the best tool repairing channel on youtube,very good job.What is the "glue"that you use on the armature,maybe a epoxy glue.And why you decide to use it here
The best restoration channel is "My Mechanics"! He does a great job on anything that he wants to restore! But the "gear show" restores very well too!
Cará eu também dou manutenção em ferramentas elétrica temos umá oficina aqui no Brasil em Florianópolis está semana eu desmontei umá desta deu o Bicho foi para dar um jeito foi no oring do pistão funcionou está OK. Mas o problema é peças mas teus vídeos são Boms valeu é um forte abraço
Esse senhor, dono desse canal de restauração, é japonês; então ele não terá como lhe entender, se você não sabia... Hehe!
well done
how many days?
nice
what are you using to clean the plastic casing??
em hỏi chút, dung dịch tẩy ốc vít tên gì ạ. Có phải RP7 hay ATM
Mr. Sophistication
Sorry but I have a question for you...why you don't use the sandblaster for this type of work??? Thank you....
Why you used transmission fluid instead the grease from Makita? Also, what is the product that you used to clean the motor rotor cavities? fantastic work. Thanks for the video.
Transmission oil performs better than grease. I use anti-rust spray to clean the motor rotor cavities
Muito bom :)
Thank you!
This would be more useful with some commentary, like why some elements need to be replaced, or the color of the grease or something.
Good
What kind of puller set you using?
After what was done on the rotor, it should be balanced dynamically. The commutator is not cleaned by sanding but instead rolls on a lathe in the bearing
@Clint Morningwood Ok :)
t's just information that can be useful. I have been repairing such burned engines for 30 years
Why the copper coils? Did you cut these off first and I not see it? What do these do? Great restoration as always. This beast is a war crime waiting to happen.
What’s the white powder you used to clean with water?
Now I want to go to my local junkshops and look for discarded tools to restore.
Cept they'll be all 220v.
Rather than see them get torn apart for metals, I'd like to restore it for my personal use.
Oh nice to hear that 👍
