It's taper tap, plug tap and bottoming tap For starting the hole, enlarging it a bit at the end of the blind hole, and finishing it with bottoming tap for full threads to the bottom. If using a device to keep it straight (a thick plate with straight holes in it, a spring loaded center in the drill press or lathe, etc) a plug tap can be the first to be used and then the bottoming tap. Taper taps are good for hand taping and eyeballing squareness. The taper makes it go straighter and self align.

For metric taps, you can determine the tap drill size by subtracting the pitch from the diameter. In this case it is a M10-1.5 thread. 10-1.5 =8.5 no table needed.

Yet another advantage of the metric system

Thanks - I never quite understood about the reason for having to use the three taps as opposed to just the one. Really helpful video. Very clear explanation and demonstration.

Handyman, thanks for the advice. I started out with small size bits, then moved up to the final size, I used 3 increments. It worked perfectly. To be fair, I don't think it was cast iron, I think it was just "aged" steel to make it look like that. Basically rusted. Your video and advice helped, I haven't had to tap holes for 30 years so your refresher was just what I needed.

Thanks! I made my first three taps today. M6 through two 1/4” steel plates. I only had one type of that taper so it was a great guide to get it right the first time. Now I have my foredom rotary tool attached quick change tool holder for my lathe. Cheers!

brit, man.

I was taught the taps are called a Taper Tap for beginning and a Plug Tap for finishing and dead holes. Never seen a set with 3 taps. Good video.

if you want a reliable way to do a straight tap without using a square, you can use a squared ?"x?"x1" thick block of aluminum and drill a 10mm or 10.1mm hole in it (for a M10 x 1,5 obviously).Then you just put the block over the hole you want tapped.I suggest this because you only checked one axis with your square (that we could see). Your tap could be off in the other axis and you wont notice it unless you check all around.Just drill all the common tap size you need on one block to save time.

What I use as a tapping guide to help make perfectly perpendicular holes are pre-tapped pieces of steel (done with a drill press) which I start the tap inside and align with the hole, clamp it in place if possible and start tapping the piece. This is when the piece I am tapping is too awkward to tap on the press. Give it a try and if you like the method, feel free to post a demo.

You're an excellent teacher-thanks-Michael-Australia

The third is called a bottoming tap on this side of the pond. It's good for starting holes but also for tapping blind holes because it allows the thread to terminate at the very bottom of the hole.

Thanks for the great video. This is all new to me but now I feel like an expert. :) I agree that having the right tool makes a huge difference but having a quality tool is essential for this kind of work. My other tools are the best quality I can afford and I've never had a tool break or bend etc.

amazing video im looking a good way to do it and this is the way to do it

For SAE, the body drill is the major diameter +.030". So a 1/4-20 thread= .250+.030=.280". Find a drill and tap chart either online, on your phone, consult a book(yes they still exist) find .280" and that's your drill size, in this case it's a 9/32nds. Also, if you like budget friendly tools, I'd recommend a half turn fwd, quarter turn backward and it should save some stress on the tool. Often times taps and wrenches break because the chip gets too long and gums up the hole. Thorough video thx

@bestamerica always good to know the old way of doing it, never know when you won't have electricity.

Tap wrench probably cracked because you were applying too much pressure when turning the tap, best to turn tap through half to three quarter turn before reversing to break off chip, especially when using smaller diameter threads.

Thanks for the video I have to do this tomorrow, hope its ok 👍

Great video but I have a question. How difficult is it to drill and tap into an iron railing? I have a gate that I need to drill and tap to add a lock to. I'm a little concerned about drilling and taping holes into iron. It's been years since I've had to drill and tap something and the iron adds a degree of difficulty.

For metric, subtract the thread pitch from the tap size. 10M-1.5 = 8.5mm hole. 6M-1.0 = 5. So a 5mm hole for a 6mm tap ONLY works if the thread pitch is 1.0. If the thread pitch was .75, you would need a 5.25 hole for a M6-.75

ULTIMATEHANDYMAN...Love your work mate. Just a few questions:1). I'm about to tap a hole in a car - the plenum chamber really and I need to tap into about 10mm approx....now the hole size I want is 4mm but the thing is that I've already drilled the hole and it's exactly 4mm...I don't really want a bigger hole size. Could I get away with this and do you also think I only need to use the initial tap in order to go through 10mm instead of using the 3 taps. Thanks in advance. Cheers

Use a drill press, turn it on and then turn it off again and let the momentum of the drill press make the tap work its way down untill it stops by itself. Now you can use a tap-holder to do the rest of the work and it ensures that the thread is perpendicular to the workpiece.

@ultimatehandyman...It ain't a blind hole....I drilled through the other side.So U reckon if the hole's too big then I should use a Plug tap or a Helicoil insert? Cheers

There is a chart on this page- www.ultimatehandyman.co.uk/how-to/metalworking/tap-and-die If you are ever stuck and don't have a chart, you can deduct the pitch of the thread from the diameter of the thread and that will give you the drill size. Example- M10 X 1.5 pitch 10 - 1.5 = 8.5

Do you know if those taps can be put in a drill press?

@ultimatehandyman

9 жыл бұрын

Yes, but you must grip the round shank and not the square on the end. It's common to use them in a drill press to get the tap started and ensure that it's parallel, you can't of course switch the machine on to tap the hole unless you have a special tapping head attachment.

@@corporaterobotslave400 Oh, OK (no problem) Taps are made from a very hard steel, but hard steels are often brittle. So, whilst they are very hard, the steel can easily be broken, as it is not flexible like a mild steel. If the tap breaks, you need to ensure that you are drilling the correct diameter tapping hole. There is a chart on this page for metric tapping sizes- www.ultimatehandyman.co.uk/how-to/metalworking/tap-and-die Once the correct sized hole is drilled, you need to start off slowly and ensure that the tap is kept as straight as possible, don’t forget to reverse the tap every few turns to break off the chip.

It's all fun and games until you have to tap 3x holes in 70 piece of metal :\

I've found that you have to push down on the tap as you turn it, especially to start with. Otherwise at the start, the tap just eats out the metal before finally getting to threading. That's my experience anyway. I push as hard as I can until the tap's halfway in. Using taper taps.

Never use cheap taps and dies for steel...
