15 Year Old Impact Driver Restoration | Hitachi Cordless Oil Pulse Driver, Model WP 12DM

I bought this impact driver only 15$ cause it looks very old and the battery also dead. There is some water inside the box I think I couldn't get it back to work. Incidentally, I picked up another battery at good condition. The seller gave it to me for free. Finally, I can get this impact driver back to life. This tool is really powerful and greatly reduces striking noise. At the end of the video, you will see the drill testing and comparing.

This procedure is only slightly different from my own preferred restoration method: 1) Tear down the tool to the smallest components, de-greasing and performing rust removal along the way. 2) Forget how all the pieces go back together. Put them all in a box and set them out on the curb on trash day. 3) Purchase a new impact driver.

I'm seriously impressed that a rebuilt 12v Hitachi is that powerful. Also, finally a tool restoration channel that feels "achievable" given what I actually have on-hand in my shop.

[@blacksunapocalypse]

Just watched 21 and a half minutes of a power tool restoration. Didn't get distracted at all by anything else. I end up checking my phone sooner during tv shows I like.

[@dimitar4y]

that's cause it's interesting and has new things. Your TV contains the same braindead shit that you've seen a million times, you're just brainwashing yourself that you like those shows. Get a hobby and kick the TV gone. It'll do you and your family real good.

[@AJRestoration]

I love seeing a old tool happy again!

[@EspresserChannel]

The best restoring channel. You have inspired me to buy old electric tools and restore them for my workshop instead of just buying new ones. So far It's really cheap to get great tools, that I simply couldnt afford otherwise. It's so much fun to bring them back to life when someone has abandoned them.

[@EspresserChannel]

@Klippy Klop I''m in the process of restoring them and I have a thing for old german Fein power tools. I was thinking about uploading a restoration video, but It will take me a while to do so. I'ts going to be a long process, but maybe someone will find it helpful or at least entertaining. Thank you for your comment. Cheers.

[@MrSkyY06]

The best is "my mechanics" go check

[@EspresserChannel]

@@MrSkyY06 It's alright channel and thank you for recommendation, but it's nowhere near gear show.

[@xenonram]

@@EspresserChannel My mechanics is more detail orientated. For the white buttlene over molding on this drill, he would have CNC machined a new mold, and re-shot the over molding instead of keeping the dirty white/yellow. Much higher level.

[@EspresserChannel]

@@xenonram I agree as well, but at the same time I've been troubled with his coffee grinder restoration. I'm coffee machines / grinders oriented and he should have either buy new conical burr or create one. He just cleaned the old one, which makes his entire restoration useless, because he will never get decent coffee out of that. Kinda pointless restoration. But I fully agree on his craftsmanship, he is really skilled.

Andrew Delashaw I was just saying it drives screws extremely slowly compared to even the cheapest modern impact driver.

[@witgangyounotube287]

you can tell a tool's age just by looking at what screw type type they use, in the near future we won't need any screw's or drivers, everything will be welded/glued together, ironically that's the age we get screwed.

[@jsarratt1]

Yeah...talking to you Apple!

[@bonesrhodes3762]

--- we have passed that event horizon: back in the 80s Honda produced a series of small motorcycles for their domestic market in which the engines were pressed and riveted together - no removable fasteners. They also offered NO engine repair parts - you could, however, buy a complete replacement motor.

lmao

[@canesvenatici9588]

Never buy that kind of stuff. They won't be able to pull a dick move like that if ain't nobody buy them. Also, make fun of people who bought that kind of junk when their stuff got blown up.

One guy's warranty service was denied when his iPad bent and cracked the screen because he put his iPad inside his backpack. He had to pay $600 to fix the damn thing.
