This was a super informative video. Well done!

This is what I call explanation. Very clear explained, could not be better.

Also the cross-section examples blew me away. Incredible effort! This style of teaching should be a staple in any shop class or engineering curriculum.

I have learned more about taps in this video than in forty years of hand taping stuff. And this video and Marks great diction is top notch, Thanks

I know how painstaking it is to make a video like this. And the 3D graphics are awesome. One of the best tutorials over the net I must say. Please keep up the good work. I'll recommend your channel to my group of hobbyists too.

I'm in the UK, and I would call them Taper, Second, and Plug. Thanks for these great video's.

Wow - that was the gold-standard of instructional videos! Nice pace, concise explanations, clear examples and demonstrations!

This is the type of stuff that should be taught in high schools. Easy, informative and useful.

Well I definitely just learned a lot about taps. All very useful info, thanks.

I hope Haas knows that these videos actually sell Haas machines. I know more than a few people that have decided to buy a Haas because of these great videos. Great video and presentation Mark!

I learned drilling and tapping in the '80's. My Son is a welder and he not only didn't know about tapered-straight-bottoming taps, and their uses. He was shocked that I did. I recently bought 2 new double sets in SAE and METRIC tapered-straight. He wanted to borrow a tap for one of his side jobs. It ended up being a half hour lesson in the different types of taps, oil and water based cutting fluids and their cleanup. Sometimes I feel that he believes that I'm making things up. Will be forwarding this video to him. It's nice to know that something I learned over 35 years ago is still relevant.

Didn't think he was going to mention Japan. Not gonna lie feels good to be recognized. Taper tap here is called "先タップ" (Saki-tap) meaning pointed tap. Also numerically referred to as"1番タップ" Plug tap is called "中タップ" (Naka-tap) meaning middle tap. Also called "2番タップ" Bottoming here is called "上げタップ" (Age-tap) meaning raised tap. Also called "3番タップ" Straight tap is called "ハンドタップ" (handotappu) which just means hand tap. Spiral point tap is called "ポイントタップ" (pointotappu) which just means point tap Spiral flute tap is called "スパイラルタップ" (supairarutappu) which just means spiral tap. Thanks for the great content!

As a former cutting tool company rep, I consider this to be one of the best tutorials on the subject of tap performance and selection that I have ever seen. The examples and illustrations make understanding some of the issues with tap selection and threading holes much more understandable. While there have been countless books written on the subject this 13-minute video is a perfect primer for those interested in making the right tap choice for the job. The basic rule of thumb as the instructor mentions is use a tap that pushes the chips down and out of a through hole or one that pulls the chips up and out of a blind hole. If you are stuck using a tap that pushes the chips forward and down into a blind hole you can "peck feed" the tap in multiple steps into and out of the hole along with using either compressed air or high coolant flow to flush the accumulated chips up and out of the hole until you achieve full thread depth.

Learning has occurred this day. Exceptionally informative video

Possibly the best explanation ever in the history of anything.

This is the way every teacher of any subject should have been explained the subject

I can only begin to imagine the amount of preparation that went into the making of this video, as well as the technique and the craftsmanship to deliver all the physical samples. Only a set of really skilled, really passionate people sharing the same set of values can pull something like this.

Excellent video! I've been a machinist for 43 years and I learned something from this. You presented the information in a way that made it easy for anyone to understand. Keep up the great work and I will definitely be watching more of your videos!

5 YEARS MACHINING EXPERIENCE AND IM JUST NOW LEARNING ABOUT THIS! HOLY SHIT YOU LEARN SOMETHING NEW EVERYDAY LOVE THIS INDUSTRY!

Those informations are all out in the internet, but no one can present it as easy and compact as you do. Information and entertainment on another level, Mark is the best!!!

This is easily the best video I have ever seen on the subject.

I have never used a tap before in my life, but after watching this awesome little video, I feel like I have a qualified certification in taps! This guy is a teaching jedi! VERY well done!

This video reminds me of the clarity of those old Bill Nye The Science Guy videos i grew up watching. Amazing work.

I came here to just make sure I had the correct saying for the wording of "tapping, tapped, taps." Instead I enjoyed the video and the information. Even though I may not use this in my life, the information is valuable.

Very handy video, thanks! I'm in the UK. Hobby mechanic and I usually call most styles of tap "dirty f*ing broken piece of s*t b*stard".

This video is incredibly well made. Very clearly explained and excellent use of both physical and graphic demonstrations. I learned so much and really appreciate the thought and care that went into making this video.

I think everyone in my mechanical engineering course should watch this video. Too many dont have any practical knowledge

At 62 yrs old, & just getting into the hobby of Lathe & Mill machine work a year ago. I knew the time would come when I would need a Tap & Die set… And that’s about all I knew about a T&D set was it’s name… So this being my VERY 1st Video to have viewed was ABSOLUTELY PERFECT!!! Smooth Instructional & Technical video.. example with the Snowplow was brilliant ⭐️⭐️⭐️⭐️⭐️ ZenModeling

A really practical explanation with enough clarifying images but without making you feel stupid by overusing them. I think it's a nice balance

I am amazed on how incredible informative this video was. This is what makes KZfaq worth watching. Thank you.

I'm Not a machinist, just a curious person who as manual tapping once, and wow! it's a realy great video, clear, simple... So nice !

Gosh, i've learn more in 10 minutes with this video than 10 years working in welding shops

Hello from germany! :P I think, this will twist your tongue, but bottoming taps in germany are called Sacklochgewindebohrer :D Sackloch = blind hole, Gewindebohrer = tap

Thanks for a thorough crash course on one of the most dreaded operations in precision machining. Love your Haas tip of the day every chance I get to watch and learn!

I stopped the vid less than half way through to write this: my supervisor at work suggested this channel yesterday and I subscribed today. I've been machining for over 11 years now and I've learned something new from each video that I've watched today. This is excellent presentation and a great mixture of explaining terms without just expecting the audience to know all the jargon. I'm already glad I subbed!

Excellent video, with good aiding graphics too. Thanks ... and yes, most of the taps I've broken are spiral flute. :|

Thanks Mark for the taps lesson! I'm a medium skilled diy guy, have tapped (and ruined) many holes, never REALLY knew what I was doing. I now work almost one-handed after a stroke in 2011. This makes everything harder but I keep trying. Back around 2013 I attempted to helicoil some head bolt holes on a corroded 185 Johnson outboard. I used the usual t handle tap wrench, and could not for the life of me manage to align it, ruining 3 holes. For the remainder I used a ratchet wrench and was able to hold it in position with the good hand and turn with the impaired hand. But the ruined holes don't leave enough material to go oversize, so the professionally rebuilt short block is now trash, several thousand $$$$ down the drain. Obviously, helicoil taps are bottoming, don't align. NOW you tell me!!! Well, my inexperience got me. Wish I'd seen your tips sooner! Or at least tried the ratchet approach first. Great videos, even for a guy who will never touch an NC machine.

As a Machining Student using Haas machines, I greatly appreciate all of these "Haas Tips of the Day". Thank you!

I'm trying to learn more about machining and tooling used for machining. The Haas Videos are always made so well that a guy like me can learn easily when I know nothing about the subject.

man, from my heart, thank you, im a semi trained professional & have always wanted to know this. I worked at Norva plastics in Norfolk & no one there could ever explain the difference to me even though we had 2 haas mills & 1 haas lathe

I've been tapping holes for 48 years. Was taught and learned from some good people but even I picked up on a couple of things here. Thanks Haas.

Great vid. Thanks, very informative. In Australia Taper = starter, plug = intermediate, bottoming is bottoming.

I vote this the best thing I’ve learned this year. I bought a tap & die set and had NO idea about what you just taught me. I just thought there were plugs, tapered and bottoming. I never considered which way the chips will fall, just like at the casino, This noob thanks you so very very much for teaching me and explaining it with a cool snow plow. My inner child was so happy to learn more more more.

I've been working in a cnc shop for going on 3 years. No one has given me an explanation I can understand till now. Thank you

Thank you. I've been a professional mechanic for 14 years now, and tapped hundreds of holes, all by hand. The info in this video will make these tasks easier in the future and probably also enable me to produce higher quality repairs.

I have been a lathe guy until I switched shops now milling and my boss likes me to use your videos to boost my level of abilities. Thank you for making it easy to learn about things that were not taught in my training!

Right off the bat I’m no machinist but that said the industry really fascinates me so thus how I’ve stumbled upon this video, I’m young and basically my mechanical knowledge is based around what I’ve had to fix myself to keep myself moving forward and I do have a craftsman tap set and man it’s saved me several times from having to buy a new part but never did I ever think this much about tapping or ending with a quality tap, just did it and went on my way but I’ll tell you this video not only really interesting but extremely useful on how I will think about tapping from now on. Also this is a extremely well produced video, between the graphics in the animations and the Pronunciation I really enjoyed this video.!!!

It`s awesome how easy a topic can be, if it is explained well.

Been using taps most of my life... and at 60 yo this old dog found Mark very interesting and even learned a few things!!!

You know taps, my man ! In our shop, we worked a lot of titanium. Our machinists always had a coffee cup full of talcum powder next to their tapping operation. Taps have a nasty tendency to quickly gall, then snap. The talcum smoothed the operation, and fewer broken taps.

Dang!! Mark explained everything I ever needed to know about taps. I don't need to watch anymore videos.....EVER..!! Excellent visual aids and editing. Using real metal models is a lot of work but makes it so clear and easy to understand. Good job, sir..!!

FINALLY, A video showing the proper functioning of a tap.! THANK YOU !

This is a tip-top tap video. I learned about taps from the tip to the top, and the top to the tip. And with a bit of swarf thrown in as a bonus, perfectly done.

This is f****** brilliant! The time, effort and thought put into this is amazing.

INCORRECT... title Corrected: " Every tradesman needs to watch this". An EXCELLENT presentation. If only I had seen this video 38 years ago!

Gotta tell ya - i was really arrogant starting to whatch this video..."Who doesn't know about spiral flute taps?"....But you did it in such a detailed excellent manner I even learned some stuff. GREAT GREAT job guys.

I find it amazing, how after reading all the comments that no matter who you are or where you are from there is an air of solidarity and kinship, with mutual respect among all of the people doing work like what's shown in these videos. I see the same basic principles in comments in most trades including, but not limited to, welding, carpentry, gunsmithing, electricians and blacksmiths. All traditionally blue collar trades. Humph, interesting. It shows we all have more in common than we have that separates us. It doesn't matter if you are Chinese, Mexican, Russian, Canadian, Cuban, German, Scottish or American. One needs to watch any of the varried " competition " reality T.V shows to see sore losers and bruised egos. But if you have ever watched Forged in Fire, you will see the difference. Those eliminated, or the looser, always exhibit fair play, own up to their mistakes and failure explaining why the decision was correct and how they will learn from it and strive to improve from the experience. All the while congratulating the winners. It's a wonderful display of recognition of talent and skill and fellowship for those who bettered them. It's a beautiful display of respect and pride amongst likeminded peers. And the way all people should look at others, not with envy and anger, but with respect, pride and camaraderie. You can learn a lot from others, no one can be expected to know it all and be the best all the time. You get out of a skill or trade what you put into it. And I personally find working with my brain and my hands to be the most fulfilling thing in my life. And I love to share what 50+ years of smithing has taught me.

One Word: Perfect! Perfect explanations with a perfect actor. Thank you very much :)

Wow, I am 65 and spent 8 years working around a machine shop.....I learned so much from this....thank you very much......

Superb explanation without any flaws Sharp explanation Broad view Deep knowledge

Wow! I was expecting to need to go through like 2 -3 videos for the information I needed, but this covered all my questions and then added things that I wouldn't have even considered. Thank you!

A very helpful video for hobbyists. I love the snow plow! 😊🌎✨

This is what a real class should look like. Awesome content.

I knew Haas made exceptional machining tools and equipment, but I never knew they also made some of the very best educational videos!

These videos really make me think that Haas care about their customers. Refreshing, so many manufacturers aren't interested when they have your money.

I'm watching this and after you've grabbed the truck, I'm like "wait no way, how didn't I think about that". Now that concept will never leave my head - it's a lot easier to understand, than to memorize. Awesome. P.S. In Russia these taps are called simply "roughing, semi-finishing, finishing", and are marked with 1,2, and 3 rings on the shaft, for those who didn't watch this video, so they wouldn't mess it up.

I love to watch American instructional vids! I am a business / managerial trainer, consultant. Good chunk of learning here! Awesome instructor, perfectly organized instruction, super visuals! Thank you!

I have tapped a bunch of holes, some by hand, some w a drill press and a spiral flute tap. I try to learn what I can, but I was never formally trained. That said: this video was amazingly clear and helpful. The illustrations, close-ups, and descriptions along with the flow of the video was very well thought out and executed. I found it painfully easy to understand and follow. Very well done. Thank y'all for the time and effort to make this video.

What a Brilliant well planned & presented video! I'm not a machinist but I learn where I can. I found the presenter to be not only very knowledgeable but very easy to follow without him being a "know it all" on such a basic subject which is the way many come across. The prepared examples are high class & again, very well explained! I hope you have done other videos of this caliber that I can learn from. Thanks!!

i use bike specific taps from Park Tool. I had no idea there were other types. I thought a tap was a one way tool but now I know so much more ( and how much I still need to learn ) ! Thank you for an excellent posting!

Lot of folks here may thumbs down this one, BUT! I am semi-retired now and no longer have the access to those beautiful high $$$ machines, basically I just do some "hobby" and such stuff from my "roll-a-way" shop in my 2 car garage. I get 1/4 - 1/3 of the garage, the wife gets the rest to park her precious in. she'll be the first to tell you though, "I like him having a place to get out of my house, & hair for the day, and even make some unique fixtures and such that are appreciated and useful." She's happy and so am I! I just fabricated 14 new hand rail posts from 3x3x1/4" Sq steel tube for her new ornamental steel deck rail with 8 1/4-28 threaded bolt holes for the rail attachments in each of the 42" tall post this way with the same tap. Not the first time using this method, been using it for a while now. With that said obviously I do a lot of my projects with minimal tooling. When it comes to doing projects with multiple holes to be tapped I have come up with a way of doing my "hand tapping" with a little better expediency. Once I get the drilling done on my mediocre drill press I start all of the hole to be tapped with a tapered spiral point by hand then shift a more appropriate tape for the particular job, blind or through hole. I put the tap in my "brand name" battery drill, set the drill chuck clutch to a lighter release pressure and finish out all of the tapping with the drill. Start the drill out with the clutch set fairly light, & turn the clutch a little tighter. I've not broken a tap this way yet, & it actually works better, and quicker for me than taking the tapping attachment i have for my drill press getting it setup and running right, especially on a larger piece needing to be tapped. Love it or hate it, it has worked well for me with my limited availability of the proper machinery. If you get the first started thread straight and let the drill walk its way down while keeping it steady in your secured piece of work, well like I said it has worked well for me. Might want todo a few practice runs on some scrap first. AND thanks for the video, excellent information and guidance on choosing the right tap for the job!! Using the right tools is always a good start... when you have them available!! ;^)

Great video Mark, this is gold dust to us self taught engineers

I have to say you've taught me as much or more than my technical school. Thank you for the knowledge man.

I've learned more from this channel than I have in my entire machining apprenticeship

This video change my life I used to think you werent chill, but i guess after watching this your chill.

Fascinating! I'm a guitar player but I've got no gigs due to Covid Restrictions so I'm attempting to do some DIY. This guy's *got it*. Top marks, fella! Thank you.

In Hungary hand thread cutters are the following: 1. Elővágó (~precutter) - marked with one ring on the shaft 2. Utánvágó (~aftercutter) - marked with two rings on the shaft 3. Készrevágó (~finish cutter, finisher) - no rings on the saft But in here these are not the same as in US, because the nr. 1 and 2 are not have the full thread profile. They cut out first ~55%, then ~25% and for finishing the last 20% of the material. In machine thread cutters we have: Straight flute: Egyenes élű (same as in english) Spiral flute: Csavart élű (~twisted flute) Siral point: Terelőhornyos egyenes élű (~deflector grooved straight flute)

What an awesome introductory class! It was exactly what I needed! Well, more than I needed, as I’m merely cutting threads for bolts in a cast iron table saw top by hand. But, that was an excellent, easy to follow, yet informative instruction guide! Thank you!

I'm not a machinist and I've never tapped before, and now I know enough about taps that I can if I need to on a project in the future! Awesome video!

geez, the quality of these videos is amazing. Not just the vision, but the content and level of explanation. great work!!

One of my less than capable corporal aircraft engine mechanics broke off a tap in a burner nozzle flange, broke a HSS drill in the hole trying to drill it out, broke a cobalt drill trying to drill that out, then came and told me. There was a wheat grain size lump left in the hole. He asked if I can remove it. My first question was why did you not call me when the screw was tight. Then the next 60 questions flowed like, where did the swarf go? What condition do you think the threads are in now, and yes i can fix it, by doing an engine change.

I absolutely loved your video ! You must have spent an awfully long time preparing it ! At about time 8:10 it shows a build up of chips . After 4 decades of working in aircraft/aerospace I remember that problem too well ! Too many self a claimed technicians were using wrong taps or should have drilled all the way thru but didn't ; or at least drilled deeper to accommodate chip clearance . This brings back old memories of parts being returned by customers wherein chips absolutely jammed internal threaded holes. We ended up drilling all the returned parts thru , with specially made/purchased extra long drill bits with slightly smaller than the min I.D. of the internal thread . FINAL NOTE : Again , I loved your video ! In my opinion a lot of guys should be getting more education just like your video ! Have good one ! John H. Toronto , Ontario in Canada .

Thanks for the comprehensive guide. This video saved me from doing a mistake as I have no experience in tapping. I needed to tap a corroded thread on blind hole. I was going to use straight plug tap while I was supposed to use spiral flute bottom tap. I didn't know the difference when purchasing the tap. Thanks again.

Thank you. Since this was made by a large company I thought it would be more of a commercial than an informative video. I was wrong. Great info that was concisely delivered and clearly explained.

What a great visual explanation. Thanks to everyone at HAAS! These vids are such a great resource for young people like me.

Crazy how much effort is going to these videos! Thank you. Keep it up !

It blows me away that this video was released for free. This is the kind of quality I always expected from those online subscription course sites, only to get some dude who doesn't know how to teach, droning on, occasionally using a whiteboard

Man you made one of the best KZfaq videos ive seen. Perfect!

Can't get enough of these tutorials. Keep them up.

Greatl video. Textbook example of how to explain something very clearly to anyone. Well done!

Awesome video! With my manufacturing class closed I've been watching the video's from this channel and I'm learning so much

Came here to watch Formula 1 cars. Taps didn't disappoint, watched the whole video and found it really interesting and well explained, I actually learned something. Thanks

What a wonderful high quality video. I've learned a lot of this the hard way, but still learned some things - and this is VITAL for anyone new to taps.

Thanks for a great video. Definitely learned a thing or two from that. Here in Sweden, taper tap = förtapp, plug tap = bottentapp, spiral tap = spiraltapp. The general term for "tap" is gängtapp, where gäng means thread.

Solid instruction for anyone needing basic tap-related information. Thanks Hass Automation and Mark Terryberry.

I clicked like after two minutes in because I could tell this was a quality video. Was not disappointed.

So how long did you play with the snowplow after shooting the video? Great video 👍🏻

Hi. In the UK, with 44yrs workshop experience, I have only heard the 3 taps being refered to as: 1) taper tap. 2) 2nd tap. 3) plug tap. In other words what you refer to as the "plug tap" is the last tap to be used in a blind hole to finish of cutting the thread.

I was just thinking about When the shavings get stuck at the bottom of the hole when ur tapping threads , and then I see ur thumbnail, it was the same image I had in my mind , what a trip that was to see at the same time I was thinking it

Mark: so many things I have never heard ! Great class., so many things to learn. You are an expert technician and great communicator .
