This is a basic discussion about three of the most common tap styles, Hand taps, spiral point taps, and spiral flute taps. I seem to get many comments requesting info on taps so here you go.
Hand taps are great for all general purpose tapping needs.
Spiral point taps are great for through hole tapping.
Spiral flute taps are great for blind holes, and power tapping.

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!!

THIS! This is what I love about KZfaq. 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.

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.

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.

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.

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!

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.

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.

Thanks Adam. The casual (mainly armchair based!) machinist in me never thought about this before but, presumably one issue with the partially threaded spiral flute tap is, if you go all the way through the work-piece such that the threads of tap are no longer engaged you have to be careful getting the tap back up and out again? Best not to let it go right through in the first place I guess!
@Abom79
@Abom79 6 жыл бұрын
You are correct. For my manual machining I visually inspect the tap as it clears the bottom of the hole then reverse it. But for through holes best to use a spiral point tap.

Spiral flute and spiral pointed work better for machine tapping as they give a shearing action as they cut . Takes a lot less torque to turn them. Any tap cuts much like a broach . Each thread cuts the thread a little deeper till the last full thread with clearance makes it a full thread . The GH number marked on the tap refers to how many half thousands above the nominal size it is. Or how much clearance it will cut for the screw . Everything you was spot on . I sharpen cutting tools for a living . A sharp tap cuts way better, less likely brake and cuts a much better thread . That's how a lot of taps are broken trying push a dull tap .

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.

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.

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!

Just FYI, in the UK we call them " taper, second and plug. A bottom is something entirely different!

Tapping guns are kind of like an air drill with forward and reverse on the trigger first click goes forward and then the second click instant reverse. There used on assembly lines in production work. Gun Taps are normally harder to break off than other kinds of taps.
