This is my 200th vidja! Incredible how time flies, still having fun in the shop, still making lots of mistakes so you don't have to and still inspiring Trolls to lob spitballs from the know-it-all-do-nothing peanut gallery.
The matter at hand:
I bust a crappy tap and show how to get it out in the home workshop.
There are many more-or-less effective ways to remove a broken tap. This is the toughest situation, a broken tap in a blind hole. In a thru hole, you can go for the hammer and chisel brute force method.
Sometimes despite our best efforts to the contrary, things don't go according to plan, so we try something else. Surprisingly, that something else works better than the original plan.
Feeling the weight of all those two dollar coins in your pocket? Throw 'em into the hat and we'll make something out of 'em!

Back in the early 80's, a friend of mine was a machinist and I had asked why he used Chinese taps. He said, have you ever tried to get a broken American tap out?

Thanks for the broken tap extraction tutorial. This has allowed me to not only remove a broken tap, but in rapid order allow me to break off a new one.

When I break a tap at work usually use a ball endmill big enough to peck out the center. At home I just cuss at it for 12 hours till it's annoyed into vacating the hole.

AvE: " some of my viewers are upset about my racist comments" AvE seconds later: " there's many ways to skin a cat..... especially if your Chinese" lmao

I had a German foreman who never gave a cheapo cutting tool to anyone. Bless that man.

As one of my old NCOs used to say, "I'm not prejudiced; I hate everyone."

I broke a tungsten carbide tap below the surface. I used cheap diamond-tipped Dremel bits to cut between the flutes of the tap and it came out easily. Just follow the precaution of cutting in 30 second intervals and allow for the bit to cool before going back in so the diamond tip doesn't overheat and separate from the shaft.

As a tool and die machinist with 30 years experience, I have found it to be more practical when drilling out taps with carbide, to use a drill bit that is just under the size of the body of the tap. So that you drill a hole inside the body of the tap without breaking through the sidewalls. That way the tap remains one piece in shape and does not have much chance of breaking your drill bit. Then all it takes is a couple of taps with a punch and the pieces will fall out of the hole. I do love this channel and fine that this guy has a wealth of knowledge and a sense of humor to match.

"that German that's only spoken by people with a throat disease... Dutch" As a Belgian, I can tell you this was hilarious!!

This has aged so nicely

Chinese taps are great man. How else would you tap plastic?

I don't know if this helps stop tap breaking, but when I trained with the R.A.F. in the 60's they taught us to always use a good cutting lubricant, (I think we used tallow then). Also once you have the tap well started you should wind forwards one turn, back half turn and then forwards again. This breaks the cut metal swart into short strips so they don't block the hole so much. For aluminium alloys, back out the tap frequently or the swarf will accumulate, re-melt in the hole and fuse or jam the tap. Also, use a taper tap to start and then a plug to finish. A broken tap should be very rare in your workshop especially if you are drilling the correct size hole. Sorry if you already know all this stuff, but I see a lot of youngsters who don't.

Stumbled upon this vid while searching for hardened steel drilling advice. I found this very informative and watched to the end. Great video and love your sense of humor.

"Just chill out, everything's gonna be ok". 👍👍 i love this guy. Too many sensitive ppl in the world these days. You do you buddy. Keep up the badass video's

A lot of this guy's appeal is a man talking to men about manly things in a manly way. Hell yeah.

I work part time for a foreigner, we were talking about fixing something on a Sprinter van, and I said "there's more than one way to skin a cat", he said "what the F%@K does that's have to do with this,", ?? 😆😆

“When you make a Dunder headed mistake and lose an arm, Atleast the safety guy can see you got safety glasses on” never related to a joke more in my life hahaha

My old timer foreman once used a blow torch with the fine flame tip after warming it up to cherry glowing bright, he hit the oxygen lever at the exact perfect moment with the flame at a perfect angle and with accuracy and precision and blew away the broken tap from the hole with minimal collateral damage to the hole like magic.
