I could be mistaken, but I don't believe broaching is *technically* drilling. They both bore holes sure but I think semantically a broach doesn't "drill". How did he think atypical holes are made?

I was waiting for the punchline as well. How can you possible spin a tool with a hex profile and produce a hex profile in the workpiece? Even now that I see that the tool and the workpiece are spinning together, I'm still not entirely sure I understand how the off-axis nature of the broach makes it work.

Here's my comment: I think I have a well-developed sense of humor, but it is different from yours. Oh, this doesn't mean I don't appreciate yours - quite the opposite. Just when my funny bone it set for one kind of laugh, you go the other way, and it slays me. For example, the jump cuts in your audio always make me laugh, and I can't really say exactly why. I suppose you could sum up your goals as (1) Impart some information, and (2) Be entertaining. You hit both nails squarely on the head (to coin a phrase). I've never touched a machine tool in my life, let alone even heard of rotary broaches but now, 15 minutes and 50/60 chuckles later, I have a pretty good idea of what they are and how they work.

The dry humor is just genius. As a machine shop owner, the rest of the video is fun to watch as well.

[@jeffsmith2085]

you are very smart, very funny and very practical.. a rare combination indeed. I love your videos, such a wide range of topics... genius

@5:00 firing shots at Solid-Tool-Post-ers, made me laugh hard.

[@TheExplosiveGuy]

I busted out laughing so hard when I saw that, then the .1" depth of cut popped up and that slayed me lmao. I aught to make a little video like that showing our Monarch at work, we can take 1/2" cuts with that beast. It's weird hearing chips hit the ground that sound like solid chunks of steel lol, they have that "ting" sound you only get with thick and hard pieces of steel.

[@mannycalavera121]

Been machining 15 years, i never knew you could use a drift to remove the tools form a tailstock. always just wound the thing back lol.

[@AttilaAsztalos]

*glances at bearing puller in hand, quickly hides it behind back* ....yyyyeah. Yeah! Me too!

[@valkyrieedit]

I love learning this kind of content. Especially with your humorous stories and small comments. The premature video cuts also are... just perfect! Don’t stope making videos. I love this.

[@ctwalston1565]

I maintain a fleet of model train locomotives for a museum. The Athearn brand have brass flywheels with hex drive shafts! I will be making my own real soon, thanks to you! OUTSTANDING!!

I'm a 53 year old man and I just clapped my hands and said "oh boy!" when I saw the notice. But I'm still trying to understand how a rotating hex shaped cutter imparts the hex shape hole....I'll go have to go get some hex bits and tilt it a few deg and check it out!

[@jlucasound]

@@hansangb Did your lights go out? I'm 56 and every time I clap my hands, something shuts off or turns on. Damndest thing.

[@hansangb]

@@jlucasound of course I do. And because I'm 53, I can appreciate humor. That made me laugh!

Oh, KZbin is recommending a "This Old Tony" vid. Wait... a recommendation that's not over 3 years old?!?! Are you okay, youtube?!

Nice marker shenanigans😂😂

[@MisterLongShot_Official]

I fully expected the Mag pie sound effect again at the end, and was rewarded with a sly grin on my face. Another well done video, TOT!

[@fuxluck1]

I used to work at a shop where we were making high end road bicycle pedal spindles. They had hex broached ends. 1 version was of 316L, not to bad. The other was titanium. Pure hell. Broach would last about 5 parts. No feed or speed seemed to help. I called the tool manufacturer and when I told him what material we were having problems with, he choked on his own laughter and asked "how's that workin' out?" I told him I wouldn't be on the phone if it was!

Tony, please do a video on making morse tapers. Angles, why do they need tangs, should i harden them, etc. Thank you! Love your videos!

[@tracylemme1375]

A #2MT machined on the shank of the rotary broach would allow it to be used on both the lathe and mill with obtainable adapters

[@ChimeraActual]

@@tracylemme1375 That's assuming his mill is 2MT, and even if it is he could have a 3/4" 5C or ER collet already I'd rather leave that shank alone and make an adapter, just because...; Peter Slutsky , Good idea, and not too hard since he just made one. MT's with a tang are typically used on lathe tailstocks and drill presses, and are just jammed home. You need the tang to be able to drive them out with a wedge. MT's with a threaded hole in the end are meant for tools with a draw bar. In a pinch you can make up a short tang with treads that screws into the end of a draw bar MT to give it double duty.. I don't believe there's any reason to harden them for occasional use.

[@tracylemme1375]

Adapters from 30 mill taper to 2mt are everywhere. A 3mt/2mt sleeve should be with every lathe with a 3mt tailstock quill. The tang is used not only for removal but also to help drive the tool. The taper of a tool should never be hardened except with a nondriving tool ie live center. This allows the tapers to conform with each other.

[@ChimeraActual]

Re. His next vid. There you go, he's got a 3/4" tool holder for that Bridgeport style taper shank. Yes, lots of adapters available, and more you can make, I think I've got most of them . It's likely that you introduce some error that may or may not be important with everything you add between the quill and the tool, though. Real question, not argument; how does a tang aid tool insertion?

[@michaelmechex]

Dang! A ToT video about broaching! How did I deserve this?!

[@ThisOldTony]

you've been good. OldTony's watching.

[@michaelmechex]

Thank You! This week I turned more material to parts than scrap, I guess that counts! I wish it happened more often though.

[@TheGrifter62]

I don't have a lathe but after watching that, I want a rotary broach anyway. Keep making these gems

[@taylorjams4845]

I can't begin to describe why i love this channel so much.

[@lunchboxproductions1183]

Nothing wrong with a can that's got a few hours on 'er

Depends is that rental, fleet use, or one owner?

[@EvoKeremidarov]

Great video.. as always entertaining and educational at the same time... However at $600 for the tool and 8 broaches I think I'm better off buying hex bolts from the hardware shop..

[@davidjones8942]

But....... then how are you going to spend 8 hours making a 23 cent part!?!?!?!? 😂

[@randomassortmentofthings]

Apparently there's a British company called Hemingway that sells them for 40 bucks

Thanks, I watched another video where someone used one, and couldn't for the life of me figure out why it needed to spin. So, I looked it up, and watched the first video I saw, yours! You did a fantastic job of explaining it in layman's terms.
