My first rule for taps: Don’t buy “high carbon” steel taps from the hardware store (like the Irwin brand everybody carries when you need one on the weekend). Now I only buy high speed steel taps from a reputable source like Greenfield. That has made all the difference for me in my home shop. BTW I’m still learning about the various coatings they add to the HSS. Not yet sure where the hype begins on those.

Very true Tom! For those reading I'll second Tom's comment and I should have noted that in my video. Don't waste your money on high carbon steel hardware grade taps. Buy high speed steel. Even the high speed steel taps I have used that were made in China were better then the carbon steel taps.

I think it's worth the extra cost. You may need it again some day. If you've ever extracted a broken tap from a hole you already know the value of not using a brittle material for a tap. What is an extra $5 or even $10 dollars compared to hours dealing with a broken tap. Or worse, you can't get the broken tap out! Stick with HSS.

I think the coatings are useless in the home shop. Same with twist drills, coatings are only really for high production work. When getting the maximum life out of a tool is needed.

Adam, please let me thank you for providing these videos. I am a 70 year old retired computer programmer who volunteers at my local railroad museum. I work in the steam locomotive restoration group and have been learning how to be an "old school" machinist. Our shop is equipped with machine tools dating from WWII vintage all the way back to an 1874 planer. Your videos have taught me so much about setups and procedures that I am now working nearly independently. So thanks for sharing your skills with all of us!!

Great to hear!

Wonderful video, please consider more educational videos like this one and pass your knowledge on

Thanks, great stuff. FWIW, a while back I asked an old machinist why he called it a gun tap. His response, "Well, my daddy told me it was because it shot the chips out the front of the hole like a bullet" made sense to me. Thanks again!

Adam thanks for taking the time to make this video. I learned something from it as i normally do from all your videos.

THIS! This is what I love about KZread. I'm far too old and far too far into my career to have the time to go back to school and learn the basic skills I want to apply to my hobbies. Thank you for spending your time to teach, even the basics. Bit by bit, in my own spare time, I can increase my skill set. I've not tapped a hole in 30 years. Thanks to you, Adam, and folks like Kieth Rucker, I'm able to do the things I dream of.

Another succinct explanation and demonstration of practical machining!! Thanks Adam

Thank you, Adam. You have the tools and experience to point us in the right direction. I have been waiting for this video, again thank you so much. Keep the shop talks coming.

Outstanding demo and explanation. I have see you and others use different taps but never really understood the functions clearly. Love to see more of these Shop Talk teaching moments. Thanks.

Thanks Adam. Very nice lesson. Keep up the great work. Your videos are appreciated by many!

One of those subjects that has been covered many times over, but always worth repeating from the creators views and experience from each of the creators vids. You can't learn enough. Great vid Adam, and thank you.

Hey Adam. Thanks for this video. It’s nice to get those info. Keep on. Always love to see your videos. You explain everything very understandable.

Great shop talk! Merry Christmas Adam and to yours. Look forward to Saturday!

Your videos are so educational, I learn a lot from you. Thx Adam!

Thanks Adam for the talk on Taps. I'm one of those that didn't know anything about them. I have a tap and die set and about all I've ever done with them is chase a thread with them. I have a couple of spiral taps but didn't know what they were used for and how to use them. Thanks again for your shop talk on Taps.

Hi Adam, nice little course on tapping tips & techniques. It makes perfect sense... Whether it's Milling or Grilling, you da man!

you're a good teacher, abom! i always learn a lot watching your videos, shop talk or otherwise. you're great at explaining what you're doing and why, and are very methodical about how you work. i say that good teachers had good teachers, so you must've had a very good teacher.

Great video Adam. I never new the dif, just used whatever I had. Now I get it. Very thorough and well presented.

Thanks, Adam. This is helpful for us guys who have never had access to a large tool inventory. Now I'll know when to spend extra money on taps!

Very clear and good explanation of how to use taps! Thanks Adam!

I'm one of the people that didn't know much at all about tapping and taps. Thank you for taking the time to post. Reading comments below, it appears that there's even more to learn.

Great explanation, very easy to understand. I don't do any machining or metalworking personally, but I like learning about how the processes work - just for expanding my understanding of the systems we all depend on. Thanks, and keep on posting these well-produced videos.

Thanks for continuing to make videos with good information in them, both your Shop Talk videos and the Saturday Night Specials. I'll also wholeheartedly concur with Thomas Utley's comment - a few weeks ago after sitting for 1-1/2 hours with a Dremel and a small burr to grind out a broken cheap carbon steel tap from a hole (where it broke on the way OUT), I won't use them in anything harder than aluminum. Now saving for a set of HSS taps and dies.

Not being a machinist this was very valuable for me. I have a bunch of different taps, but honestly, was not always sure what the differences were or when to use them. Thanks very much. This was a big service to those of us who are not in the know.

Almost a word for word lesson on tap basics I received as an apprentice on my first rotation through drills. Dennis Armstrong on the neighboring machine and a veteran of 30 years or more in the machine shop was my mentor. He taught me the basics of drilling to the layout, drill selection, hand sharpening drills (slightly different from my Dad's way,) drilling out broken studs, etc, along with a body of information about taps including what you discussed here. You younger guys and early learners pay close attention to Adam. He knows his stuff and teaches it well. Best of all, unlike yours truly, he doesn't hose you down with too much information when teaching the basics. He gives you an excellent start on the topic then expects you to apply it learning the lessons experience will bring to you. Well done again, Adam.

I really like this format! I'd love to see most educational videos like this.

Adam Great video. In the fab shop I worked in right after high school, we used nothing but spiral pointed taps in our tapping guns. perhaps that is why they are called gun taps. For lube we used nothing but Anchor Lube on both the drill bits and taps. It amazed me the amount of life we got out os small taps and drill bits. This was back in the early '70's.

@Abom79

I have Anchor Lube and use it sometimes but it's harder and messier to apply then using my cutting oil from my Eagle, so I just use what makes my job easier.

This kind of information is priceless, I grew up without the benefit of the internet and home computers were not much more than expensive toys, a time where shop class was being phased out. One of the things you learn early on when you find yourself thrust into the real world and you're forced to make repairs on your own because you have no money (because the crap they taught you won't get you a good job), is that there are no suitable tools to extract broken taps.

Thanks for this video, and especially for mentioning gun taps. I've never quite known what a "gun tap" is and always assumed it was the same as a plug tap. I'm glad to have this clarification. Great video as always!

Great video from a great man. Thanks for the really nice video. I would like to add that there's another one used for aluminum and soft material. It has a lot of names like fluteless tap, roll tap, conforming tap. And like the name it doesn't cut, it forms the thread from cold deformation which makes the thread stronger in softs materials.

Where I am at the 3 tap set is designated, Pointy, middle, bottom. The spiral fluted tap is normally referred to as, Machine tap. And the spiral pointed tap I have plain never seen before. Thanks for the video, no matter what we already know, or don`t know, it is always important to bounce knowledge off each other, it keeps us sharp.

fantastic video abom very informative, keep um coming thanks I've learnt a lot from it

Thanks, Adam. Excellent basic info.

As always a great video. Any chance you could talk about drill sizes for different taps. Also, could you talk about die's and major/minor thread sizes. Thank you for sharing your knowledge and skill with us.

I have never had a hand tap go in so easily. It always seems like a battle - quite often w/ me losing said battle. Quite frustrating to watch someone else use a tool successfully, that just hasn't worked for me. C'est la vie! You are so much easier to listen to than your Canadian counter-part; no mumblings and oddity phrases that translate like Greek to me.

Adam, we use Dormer spiral taps at work and they work great. They are a little pricey but when you can power tap a few dozen holes before you see any changes (rough threads or binding up) is worth it to me. Nicely explained in this shop talk. Keep up the good work.

Thanks. Nice to get that basic info.

Another great video for those just starting out. One type you didn't cover is form taps (roll taps.) They are great for blind holes in brass, copper, aluminum and mild steels. They don't work well in plastics or cast metals. We use them all the time on our CNC mill. The tap does not cut. It roll forms or cold forges the thread. Because of that they call for drill sizes different than cut taps. Example: with a 1/4"-20 cut tap. You drill a number 7 (0.201") hole. With the same size form tap. You drill a number 1 (0.228") hole.

You would have made an excellent shop teacher. Glad you chose to be a machinist !

Great video Adam. I've used the basic "plug" hand taps for most of my life since that's all that came/come in the hardware-store-type tap sets. If you decide to do a follow-up to this video, please explain for those who don't know, the reason for using a spring-loaded follower and also (especially for manual machines with no digital readouts) why it's a good idea to drill & then tap each hole before moving to the next hole to be drilled & tapped. Watching you do these close-ups of spiral-pointed & spiral-fluted taps makes me want to add some to my tap sets. I think my oldest tap & die set came from Western Auto, so I'm probably dating myself a bit here, ;)

Thanks as always! Looks like I am moving down your way soon for a new job.

Well done. Good teaching presentation.

I've only broken taps in stainless, and I don't usually power tap anything except aluminum.Hand tapping is much easier if you go a little larger on the tap drill than the "chart" says. For example, using a #7 drill instead of a #9 for an M6 tap. If you have more than minimal amount of thread length it will still be strong, although a little sloppier feel when starting.

Cool video Adam!!

Ah ... a man that uses Edge Technology tools ...I have a Pro Lathe Gauge. Haven't used it yet - fits in my 3 -jaw chuck and enables me to set my tool height in my Lylak lathe. I have a bare bones tool post so I will use my Pro Lathe gauge to set my tool height using shims or precision ground key stock. I will then keep each tool and shim combination as a set. I think you get the idea - no more hunting for the right tool for my tool post. Obviously I have space for 4 tools in the tool post, with a fifth choice being a centre drill; I will use Edge Technologies Tool post chuck for drilling. This should cover most jobs with this lathe; other tools will already be a tool post 'set' if I need them. One uses what one has!

A suggestion to a follow up video would be the H Limit and class of fit. This may out of the norm for most home gamers, but sometimes it can have some practical applications. For example, I used to have to tap 300 series stainless bars that would work harden and snap taps like crazy. I found that if I used an H0 tap instead of the common H3 it would tap like butter since it was 3 thou smaller. Of course that changed the class of fit, but the standard hardware had plenty of clearance and did not pose an issue in this circumstance. Anyway it is something people can keep in mind when ordering their taps and drills for each job. I'm sure you could make it interesting for us!

Great info - Thanks adam

AvE sent me here, or us here. Only seen a few vids but enjoying and learning.

Excellent tutorial, thanks.

I love how the data on spiral flute taps have a maximum tapping depth, and that it's always just the length of the threads cut on the tap. Even though you can take it down way deep, because the shank is slightly smaller than the tap drill size. If they have a fatter shank up top where it gets driven, then that, to me, is the maximum tapping depth.

Good basic info. Thanks

Thanks sir, for precious information

You are master of machining

Thanks! I learned something.
