Nice video. Always good to see people doing it the right way. A small trick: A piece of duct tape will protect the surrounding area from the sparks, eliminating the need for polishing, in case of a surface tolerance. I had to polish a part for the food industry, after fixing a broken tap. It took forever, due to very fine surface tolerances.

EDM is the only way to go on an expensive or irreplaceable part. Very nicely done. Thanks for sharing this.

Dull taps are the most expensive tool in most shops.

He opens a box holding an edm machine and the first tool that he pulls out is a hammer!! 🤣

What a great DIY guide. Just have to get my portable EDM tool

In 1976 I broke a tap off in an engine head (455 Olds) trying to clean the threads in rocker arm supports. Took the head to a machine shop, guy said “no problem” EDM’d the tap out and didn’t touch the threads in the hole. Best $20 I ever spent !!!

I was a Wire EDM guy at my last 2 jobs, had a hole popper too for starter holes, and of course this shit haha. You’re the hero of the day when you can fix a party with a tap broke off in it though. Never saw a portable edm though that’s cool.

Definitely the best way to remove a broken tap, saved me many times.

I usually just take long punch with a hammer and shatter the tap. Fast simple and easy cleanup. Very effective on taps that size.

I thought they were gonna remove a broken tap with electronic dance music...

When we break taps on the machine we usually drill them out with carbide GO drills or carbide spade drills. It works almost every time. Always good to have the EDM as a backup though.

Very cool to see. Thank you for sharing this.

I’m still waiting for the BASS to kick in

Basically the edm version of a magdrill. Pretty Cool

Surface is damaged a little, and has caverns. If it's a sealing surface for a hydraulic flange - there can be a leaking. It can be remachined by cutting off around a mm from radial surface, but not every part allow to do that.

We have a tap burner,,,same thing,,just has it's own table,,works FANTASTIC!

I do the same work but with a waterjet. Even blind holes. Mine is messier and louder but same results. Thanks for the video.

Thank you for sharing!

I would TIG weld a bolt to it and twist it out of the hole. But your way is really cool. Excellent videos. Sincerely Robert

Я пластилином вылепливвю ванну вокруг заломыша и не засираю всё вокруг продуктами эрозии...

V.v good Excellent

Unsung heroes of our industry

I was a olympic master at running this at my old work. Haha

I learned that the key to not breaking a tap is to stop one half turn before it breaks.

Useful machine.

where on the Challenger did this part mount?

Good looking Job

Nice job amigo

Very nice

Nice EDM machine

when you break the thing that removes broken things, you know the boss is gonna sit you down for a chat about, you know, the thing.

you can some times burn a hex and use an allen wrench to work it out if not then the hammer

Hydraulic coupling?

There is nothing a machinist or tool maker hates more than a broken tap .

Kool dat waz awesome 👌

Nice, JP.

Next time I break a tap I’ll call the thunderbirds to hire out their flux capacitor

Our shop also has one of these. I have never used it though.

Not a machinist here, stupid question: Is it possible to weld or braze something to tip of the broken piece, then try to remove it by unscrewing? (Since this machine exists, I suppose no. But why.)

Walton tap extractor and Wd40 10 mins job done......

Beats pecking it with a junk endmill, hole poppers are a life saver!

I’ve never seen an EDM at first I thought it was a magnetic drill that’s slicker than snot. (I usually take a blow nozzle to clear debris from a hole with a rag covering flying shrapnel.)

Hello ... what a beautiful option ... I had never thought of doing so. Thanks for the tip.

So is a tap removal tool wired to start with? I bet my tap removal set is super cheap compared to that thing.

see that part all most scraped because of one little tap is scary

nice

How much does this edm drill?

Ive never seen this done before, so fucking cool lol

ok that's cool.

I would have had it out by the time you finished setting up that machine.

EDM process tap remove wow

Good

I'm familiar with EDM we use it to put slots and cooling holes in repair jet engine parts

Эрозионкой выжигают метчик. Прикольный аппарат.

What exactly does that machine do?

Sir aluminium kay ander say tap nikal sakta h kya

Now that I finished the video look at that heat effected zone. That material no longer has these structural strength it was originally rated to have. You have now created a crack point

Ja klasse . mach ich bei mir zu Hause auch genau mit der gleichen Maschine 🥱

We use our hole popper for this all the time.

Just bought one. I got sick and tired of drilling out work hardened exhaust manifold bolts…then the drill bit snaps off. There’s a kit for limited clearance you can attach as well that’s shorter than a 90° drill as well. If it saves my ass at least twice I’ll have gotten my monies worth out of it. Then there’s hex electrodes as well so you can use an Allen wrench instead of snapping off easy outs as well. I’ll give it a try. If it works,cool. If not…I’ve wasted more money on booze and women than that.

Где снимали? Страна?

Wow they made that look difficult Now I know who broke the tap

As a Diemaker I've tapped thousands of holes. Never broke any taps. Not! EDM is the only way to go. Carbide drills and shattering taps with a punch are wives tales. If a tap breaks off, it's in the hole to stay. Excessive torque broke it off, and intermittent cutting a broken one will almost always destroy a carbide drill bit. Punching it out destroys the threads in the hole.

Quick question. The hole thats then made tgrough the tap. Easy out or similar to extract? Still! Great job.

Aww come on EDM now that's cheating !! Get your tap extractor out like the rest of us 😳😳

👍👍👍👍👍

I bet that'll be fun to passivate.

Snap Off brand?

Наш бы слесарь дядя Витя эту хрень за 5 минут выкрутил

Hummm...different type of EDM

Thats like shooting a fly with the shotgun

Drill bit + Easy out ..but I guess firing the laser is more fun ?

Nice work sr.👍👌🏜

carbide em 4 flute 2500 rpm f.0003 will do same thing i do it all the time ;good jab any way

What is the smallest tap it can remove. 1.5 mm ?

В ответственных конструкциях не прокатит. Металл в отверстии подвергся электролизу. То есть термическиму и химическому изменению.

The most horrible noise when a tap snaps and you have a gut reaction on how to get it out.

I wonder what would happen with a carbide burr in a similar rugged setup

People at NASA will not notice that

Ну ты даёшь))) ...ребята, а есть кто-нибудь по проще?)))

only need to use magnetic drills and modified cement drills tool points and drills at medium speed

What is the meaning of wear margin

You can use tap remover also

Vary simpa method to remove the tool First to foll you want to t type round Bar and the aje and tool have conect and make arc welding after welding. T type round bar is one type of remove tool and remove.

just throw the part in the recycling bin and start over ;)

From some time there are drills for such action. Regards

Never does blend the same

Pensei que ia extrair do jeito tradicional, pontiando até dá pra pegar com o alicate😂🤣🤝👏👏

EuroDanceMusic😅🤣😂✌

What happened if this hole is blind ? And how we can remove the remaining part of broken tool?

Uses SandPaper , to cover tracks so no one knows , I have been accustomed to the sandpaper 😇

He should have coated the stainless around the hole to avoid the pitting, and no need for sandpaper. Also, what's up with the gloves? He must be afraid to get his hands dirty.

3/8” solid carbide end mill, 2000 rpm, break what’s left out

How much cost That EDM MACHINE?

Just use a easy out for taps

It's spent 30 plus minutes and probably charged the customer $1000 for something that can be fixed with a hammer and a hardened center punch in 15 seconds. The great thing about taps especially when they are that large they are very hard which makes them very brittle they explode when hit with a punch.

Vitoorrrrr

Muito interessante a máquina,porém muito caro o processo, aqui tiramos o macho quebrado com 5 min com um custo quase a zero,um ponto de solda e uma porca usada.

H2SO4-and no problem.

Masonry drill bit
