www.ultimatehan... shows you how to tap a hole using a cordless drill and a taper tap. This is useful if you have a lot of holes to thread, or if you require holes tapping quickly.
As long as you use torque control on the drill, you should never break the tap ;-) They are much easier to drill out using diamond coated hole saws- ruclips.net/video/7JCfEMrCjhc/видео.html Thanks for the comment 👍
I tap using a drill almost daily. Ever heard of "GIGO"? It refers to how a machine does exactly what it is supposed to do, and only the user can cause an error. "Garbage In Garbage Out". You don't have any clue what you're doing.
Thank you!! I tried drilling/tapping a whole yesterday, and the spot is so tight I cant fit a tap wrench inside well, which essentially screwed up my work. I've gotten a size larger tap and drill bit, and now I am more confident because I know the drill will fit perfectly. Thanks again!!
Oh, forget the comment I just made on your video about tapping acrylic, where I talked about using a cordless drill instead of a tap wrench. You're already doing it (as should be expected of an ultimate handy man ;) ). Another good addition: put the cordless drill into a drill stand. No crooked threads that way and applying even (or no) pressure is very easy with it.
@ Jerry Maguire would it be okay to use this method for a m8x1.25 Yes, as long as the drill is powerful and you use the drills torque control correctly.
I also think the taps have some limited ability to self-center if the misalignment is slight. The first ever time I tapped a hole it was by hand and I didn't use a tap guide - and the thread still came out perfect - so if I could do it OK with zero practice then there must be something in the taps themselves to cancel out misalignments regardless of operator skill.
i look forward to seeing them and learning new things. i built a forge and bought a anvil. i plan on learning new skills to save money. i think it is good because you can build tools better than you can buy them with higher qulity for about the same price as cheap made tools. it beats trying to find nice older tools 2nd hand and you never know when or if you are going to find the item you are looking for.
nice instructional video you got there :) at work were normally not so carefull when tapping, having the drill in "drill" mode or no torque limit and just go for it .P for holes 16mm and bigger we use taps welded on 1/2" sockets and an impact wrench.
If taping a single hole smaller than 6mm on an expensive part, avoid a drill as they may break tap due to human error...With more experience all drill tapping is fine.
Wow! I never thought of using a drill to tap! I'll be trying this method. I will definitely be careful! Thank you for taking the time to make, and post this and other videos! Have a Super Blessed Week!.......Gus
@@tylerlacasse5756 sounds like SoMeBoDy😉 has tried multiple projects time and time again, and has found out that they are nothing but shit at metalworking. And has nothing better to to do than to try to beat down people that are good at it. 🤭😆🙄😂 So what is ur profession? Or if u don't have it, what it ur ideal profession?
@ultimatehandyman with a normal sized mag drill you might be able to do M16 maybe M20. i have a video of the machine we have at work threading M36. that machine is the biggest portable mag drill available worldwide. it is capable of drilling 200MM diameter and tapping M52. and we have machine number 1 and 2 :)
Thank you for the vid. How do you Tap a 2 inch diameter pipe for about 6 inches? I'm trying something new with a walking cane I am wanting to make and this would help.
cordless drill, or drill press works perfectly to thread, if you're a little carefull :P i tried out our new portable magnet base drill at work the other day. ended up drilling and threading 24 M36 holes with it. at about 8minutes per hole. works quite well, but it's a lot of work drilling with manual feed.
Forgot to mention-1st step is to clamp the work piece properly haha!! It’s such a good way though for bulk applications. Have forgotten to turn the torque down and snapped a few more this way than usual traditional methods haha
This is the fastest and reasonably safe way to tap a bar. Slow forward, but fast reverse saves time on multiple holes. Use certain taps where no reverse is needed.
When Tapping a hole in Cast Iron do you use a different method, say for a M12 1.25 Fine thread, only the part on my axle I want to do doesn't have much access/ room, cheers.
I'm a bit puzzled- the tap has a square end; all the drills I've seen have a three jaw chuck- yet I see the tap turning without a wobble. Can you explain how this works? Cheers
very good video and i like it alot. i also do most of tapping using drill machine same like you.if you will use spiral tap then it would be more fast.they don't stuck like hand tap so you can go all the way without getting back.
Thanks for video because I put the tap wrong and not all the way in so it wobbled instead but I got a regular drill not the ones that I may set anything
As a future machinist I would not personally do this but whatever truly works is fine. I recommended power tapping a spot then hand tapping the rest. But hey as long as the threads are nice and smooth you should be fine. You did handle it well. Well articulated as well. You want to go back and forth so you can clear out chips and not cause your tool to break. DO MAKE SURE IT IS STRAIGHT AS IT WILL BREAK BY BINDING.
i wanna do the same for my 17mm aluminium i think through axle can i do this easily without problems?i want to install 2 squer sized bolts to atach a mtb trailer that uses i think 12mm axle mounts but my axle has a very large allen key one end and threaded other end.it should have enough thickness but its the pulling weight on the axle im concerned about.it seems like aluminium.
this is cool one more thing i can add to my shop. it will come in very handy all so great video im getting into fitting stuff up metal and steel work. i really like learning new things im going to check out you channel 5/5 stars
I have to tap a #10-24 hole tight in a corner of L brace. I can't turn a Tap handle or use a ratchet socket....I need a thin extender. Is there such a tool?
Is there smaller threads for smaller holes your trying to make internal threads for..if there is I would like to know if the drill would still for it??
I would not use a drill for anything smaller than a M4 size and even then I would be very careful as it's easy to break small taps. Thanks for the comment
Got to love these know nothing dickeads saying "Good way to break a tap" I've been tapping holes with a drill for more than 30 years, the key is the right hole size. If I use the same tap on aluminum and stainless steel the hole size will be different. Smaller hole on aluminum because it's soft material, slightly larger hole on stainless because it's hard. The drill is nothing more than a tap-matic (Google it) that you would use in a drill press, both have low speed and a clutch. Have I ever broken a tap? Sure, but it was usually do to my error, that's why I try to do a practice hole in the same material I'm using. Here's a tip: Taps are not fussy, you don't need fancy cutting fluid, motor oil works just as good. 🇺🇸
Hey ultimatehandyman, How is your success rate with small taps, say M3, or M4. Those are usually the ones I break easily, especially when using a drill.
No, for a M4 screw you would need a 3.3mm drill bit and a M4 tap, there is a chart on this page for drilling and tapping sizes- www.ultimatehandyman.co.uk/how-to/metalworking/tap-and-die I would not use such small taps in a drill though, as they are easy to break. Thanks for the comment 👍
good job man! this is basically what machinists do with a mill. It looks like your using serial taps. If your going to tap a ductile material you can use a thread forming tap. I do this all the time but with machine taps.
I would be scared to death of breaking the tap. I always feel like I have more control with a tapping wrench. I have considered getting a tapping chuck for my drill press, but I am not sure if it has enough torque and speed control to drive a tap all the way through in one shot without breaking it.
Hello, can you tap a new, bigger diameter thread, in an already threaded hole? I'm thinking of tapping a 7/16" thread in a threaded hole which appears to be around 13/32" (a 10mm bolt fits in perfectly, but you can pull it out without turning it, so threads not gripping).
Yes (assuming there is plenty of material to tap into) , but you will need to drill the hole to the correct tapping size first. Thanks for the comment 👍
@@lukejones1244 You need to follow a tapping chart, that will have the correct size drill diameter for the tap that you are using, example here- www.ultimatehandyman.co.uk/how-to/metalworking/tap-and-die
I dont get it why do we have to reverse the tap when doing tapping I've seen it in many videos but i dont get it why it is done so can you please tell me why it is done??
You always have to reverse the tap to break off the chip that is cut when tapping, even when hand tapping you still have to reverse the tap every now and again. Thanks for the comment
Spiral taps are amazing yet few if anyone rave them. They cost about 10-20% more than a normal tap...the amazing parts is the chips comes out spiral result in clean holes. On a typical tap if you don't reverse, the chips locks up then tap breaks. Some OSG coated taps don't lock up....so no reverse needed as well.
If the screw size is M1.6 diameter and thread pitch 0.35mm, do I use a 1.25mm diameter drill bit and a 1.6mm tap bit for creating the threaded hole? Thanks.
Was laughing watching him just send it in multiple threads at a time without breaking the chip. :) Just came from the garage after breaking a tap into one of my projects using power drill. I was careful going in only 0.5 thread at a time before reversing. Tens of direction changes but still was enough to break a chinese STIM6 tap. Oh well 1 hour later most of the tap out of the hole and time to order a bit more expensive Xquest (chinese) taps. ;)
Very useful video - thank you! FYI, at the very end, you described the tap as tough, but also brittle... I think you mean hard and brittle? ;) Thanks again.
had to do this as there wasn't enough room to do it by hand. can't believe it actually worked but its def worth trying when you've got no other options!
@ultimatehandyman because trying to "tap" holes like that is ridiculous. If the tap bites the drill will rotate quickly twisting your wrist around. If you've ever sprained a wrist you'll know exactly what i mean!
I use my Impact Drill & now , withe the combo Bits, I can drill & tap in the same stroke.... Thanks for your tips... & don't for get the cutting fluid...
@deckelpc you fool,hes using low torque,it'll stop well before any arm wrenching! You have obviously never used a cordless drill properly in your life! This guy knows what he is about,and has what i would consider to be the best instructional DIY videos on RUclips bar none.
@@ultimatehandyman ahhhhhh ok. I spent an hour yesterday trying to find an "adapter " hahahaaaa . Thank you so very much!!! I only have 1 arm so a drill method is my only option. Thank you again.
@@carterscustomrods Blimey, it might be a bit difficult to tap with one arm, as there is quite a lot of torque generated. You can get taps that work in impact wrenches, or impact drivers, which do not generate any kickback torque. ruclips.net/video/96LwwycOhPI/видео.html&t Best of luck with it ;-)
+Vishal Mevada This is the Dewalt DC988 but any cordless 18v machine will work for the odd hole as long as it has torque control.If you need to do a lot of threaded holes a dedicated tapping drill such as the Bosch GGW-10-E Thread Tapper is preferred.
how do you choose which tap to use lets say i have to re tap a 7/8 '' hole cause it's striped do they have sizes on them ?? im totally new to this &don't know nothing about taping so please forgive my ignorance ..
+nick diaz No problem at all, we all have to start somewhere. Yes, people often use a Zeus guide which tells you which size hole you need to drill for which size tap, or you can search online for a imperial tapping chart. That will tell you the drill size needed for a 7/8 tap. There is some information here that you might find useful, although this is for Metric taps as they are the commonest over here in the UK. www.ultimatehandyman.co.uk/how-to/metalworking/tap-metal
+nick diaz : If the 7/8" tapped hol is stripped you cant re tap it, there will be no metal to re tap, the only way forward is to re drill and tap to 1". Or fit a Helicoil insert.
+nick diaz : If there is still a thread in there you may have a chance, but a 7/8" tap is going to be very expensive, around £50, you could, if you are lucky, get another bolt, (I have no idea what it is on in your case), and cut two grooves longitudinally along the threaded portion of the new bolt, then, very carefully try threading it in, this will clean the thread, depending in what metal it is in, enough to get the bolt in, what is this thread in ? Just measure the number of threads per inch to see what it is, if it is an Imperial size bolt.
it would be hard for me to count cause it's in a manifold it's for a oxygen sensor but worst comes to worst i will weld a bolt to it i think it would the best solution ..
Im trying to drill out an existing hole in a car’s subframe so i can tap and put a thread insert. The drill jams and can’t go forward. What shall i do to make the hole bigger? Is my drill underpowered?
Probably, if the drill keeps stopping. Or perhaps the drill bit is not sharpened correctly, sometimes if the angle is not correct the bit bites too hard into the material causing the drill to stall. Thanks for the comment
Thanks for this! I'm looking at tapping a dozen holes. This helps a lot. Question for you: where can I find a soft-jaw C-clamp like you have? I've looked and have found lots of plastic junk. Thanks again!
Dear Handyman, I'd like to hear your opinion about this kind of power tapping. My question is about the device. What do you think what is the better device to do this job, what you are doing on video ? What do you recommend : 1 - DeWalt DCF-887 Impact Drive , 204 Nm torque, 3 selectable speed, with Impact Ready 1/4'' tapping tools or 2 - DeWalt DCD-991 Brushless Drill-drive, 90 Nm torque, similar to the drive on this video (but without hammer), but 2016 modern version, not from 2010. I cant decide. 1.) the device is cheaper though, but its harder to get 1/4'' tapping bits, and those are not cheap. 2.) the device is slightly more expensive and heavier, but we have selectable clutch force , and a general chuck, good for any tools. And of course they (impact drive vs. drill-drive) work in different way. Which one is better ? Regards, Laci
If you are tapping a lot I would go for the first machine, but to be honest I would get some speedtaps and use a impact wrench as they are ten times faster- ruclips.net/video/96LwwycOhPI/видео.html I have used these on site for tapping M12 holes in some 10mm thick plate and it taps the hole in seconds!
Thank you ! And no I don't need impact wrench, that would be overkill, I won't cut so big threads, but only 4...8mm. And its a big heavy machine. I ordered the DCF887 instead, thanks again.
It's normally down to time. If I'm at work and a machine has broken down it costs the firm money, the sooner it is fixed, the less money it costs them, so if possible I would use the drill to tap the holes. Speed taps are brilliant for re-tapping holes in steel floor plates as you can do them very quickly and easily! Obviously if you are making something for a critical application, you might want to tap it by hand, but in a lot of cases you can save a lot of time using a drill or impact driver. Thanks for the comment
I have never broken a tap yet, although I tend to use Speedtaps in the impact wrench now- ruclips.net/video/96LwwycOhPI/видео.html Thanks for the comment
8.5mm but I would not recommend tapping holes that size unless your drill has a lot of torque. There is a guide here for drill sizes- www.ultimatehandyman.co.uk/tap-and-die.html
Thanks! Simple, but so useful!! It’s the little details about doing small things like this that are super useful!
Glad it was helpful!

Absolutely.
Thanks for the comment ;-)
If you want to tap a hole that doesn't go completely through the metal plate, would there be any difference in the process?
I also think the taps have some limited ability to self-center if the misalignment is slight. The first ever time I tapped a hole it was by hand and I didn't use a tap guide - and the thread still came out perfect - so if I could do it OK with zero practice then there must be something in the taps themselves to cancel out misalignments regardless of operator skill.
Well, it’s tapered. Quite sure that and the rotating actiom are the only thing aligning it in the hole your threading

I want to know same. I couldn't found answer after going through 100 videos.
Can you make a video and used your impact driver. may be M12mm or M14mm. thanks :)
How much torque is required for this operation I mean I have 100nm impact drive is it enough for tapping in aluminium 40 mm deep ?????
That should be fine, but it depends on the size of the thread. A M20 tap needs considerably more torque than a M8 tap etc.
Excellent presentation! Thank you for posting it!

@ultimatehandyman because trying to "tap" holes like that is ridiculous. If the tap bites the drill will rotate quickly twisting your wrist around. If you've ever sprained a wrist you'll know exactly what i mean!
i'm gonna try this method to tap threads for my aluminium rod. thanks!
I use my Impact Drill & now , withe the combo Bits, I can drill & tap in the same stroke.... Thanks for your tips... & don't for get the cutting fluid...
Thanks for the comment 👍
does this method wark on fiberglass??
@deckelpc you fool,hes using low torque,it'll stop well before any arm wrenching! You have obviously never used a cordless drill properly in your life!
This guy knows what he is about,and has what i would consider to be the best instructional DIY videos on RUclips bar none.
Thats clever. Thank you for putting this up.
No problem!
Please put one more video for large dia tapping in vertical and horizontal position
Speedtaps are good for most positions but they only go up to about M16 in diameter. - ruclips.net/video/96LwwycOhPI/видео.html
But wont the square shank of the tap damage the 3 clamping teeth on your drills chuck?
No, you grip the round part of the tap. You can't grip anything with a square end in a drill chuck, as it will nut run true.
Thanks for the comment
@@ultimatehandyman ahhhhhh ok. I spent an hour yesterday trying to find an "adapter " hahahaaaa . Thank you so very much!!! I only have 1 arm so a drill method is my only option.
Thank you again.
@@carterscustomrods Blimey, it might be a bit difficult to tap with one arm, as there is quite a lot of torque generated. You can get taps that work in impact wrenches, or impact drivers, which do not generate any kickback torque. ruclips.net/video/96LwwycOhPI/видео.html&t
Best of luck with it ;-)
which model no of the drill used for this video
....
can you suggest some such good drill for threading purpose
+Vishal Mevada This is the Dewalt DC988 but any cordless 18v machine will work for the odd hole as long as it has torque control.If you need to do a lot of threaded holes a dedicated tapping drill such as the Bosch GGW-10-E Thread Tapper is preferred.
how do you choose which tap to use lets say i have to re tap a 7/8 '' hole cause it's striped do they have sizes on them ?? im totally new to this &don't know nothing about taping so please forgive my ignorance ..
+nick diaz
No problem at all, we all have to start somewhere.
Yes, people often use a Zeus guide which tells you which size hole you need to drill for which size tap, or you can search online for a imperial tapping chart. That will tell you the drill size needed for a 7/8 tap.
There is some information here that you might find useful, although this is for Metric taps as they are the commonest over here in the UK.
www.ultimatehandyman.co.uk/how-to/metalworking/tap-metal
+nick diaz : If the 7/8" tapped hol is stripped you cant re tap it, there will be no metal to re tap, the only way forward is to re drill and tap to 1". Or fit a Helicoil insert.
no there is thread on it just a little worn &can't seem to get the bolt in ,it's not completley stripped ,
+nick diaz : If there is still a thread in there you may have a chance, but a 7/8" tap is going to be very expensive, around £50, you could, if you are lucky, get another bolt, (I have no idea what it is on in your case), and cut two grooves longitudinally along the threaded portion of the new bolt, then, very carefully try threading it in, this will clean the thread, depending in what metal it is in, enough to get the bolt in, what is this thread in ? Just measure the number of threads per inch to see what it is, if it is an Imperial size bolt.
it would be hard for me to count cause it's in a manifold it's for a oxygen sensor but worst comes to worst i will weld a bolt to it i think it would the best solution ..
Best explanation I found. Thank you sir.
You are welcome
Thanks for the comment
Im trying to drill out an existing hole in a car’s subframe so i can tap and put a thread insert. The drill jams and can’t go forward. What shall i do to make the hole bigger? Is my drill underpowered?
Probably, if the drill keeps stopping. Or perhaps the drill bit is not sharpened correctly, sometimes if the angle is not correct the bit bites too hard into the material causing the drill to stall.
Thanks for the comment
Ultimate Handyman thanks for the response. What drill bit material would you recommend?
Is there any tools or stud for external thread using drill ..??
Not that I am aware of.
Thanks for the comment 👍
would it be okay to use this method for a m8x1.25
Good Work,Nice Instructional but it's easy to break the tap in there with a drill.Use the little T-bar and save yourself the headache matey.
what drill use?
there fluid form tapping?
Thanks for this! I'm looking at tapping a dozen holes. This helps a lot. Question for you: where can I find a soft-jaw C-clamp like you have? I've looked and have found lots of plastic junk. Thanks again!
Well ..its been 6 years later since you asked your question...Hope you found your clamps
What is the name of that fluid u just sprayed?
Metal working spray, sometimes called drilling/tapping fluid 👍
@ultimatehandyman Because all the 12 y old CoD players are so thrilled by hearing a scottish voice outside of CoD ;)
VERY NICELY MADE
hello...could i use other kind of oil,(machine oil ) instead of buying the tapping-drilling fluid?
Thank you
6 years later ...I'm not sure ?
what model is your great dewalt?
whats the mode of dewalt drill your using?
Dewalt DW988
Dear Handyman,
I'd like to hear your opinion about this kind of power tapping. My question is about the device.
What do you think what is the better device to do this job, what you are doing on video ?
What do you recommend :
1 - DeWalt DCF-887 Impact Drive , 204 Nm torque, 3 selectable speed, with Impact Ready 1/4'' tapping tools
or
2 - DeWalt DCD-991 Brushless Drill-drive, 90 Nm torque, similar to the drive on this video (but without hammer), but 2016 modern version, not from 2010.
I cant decide.
1.) the device is cheaper though, but its harder to get 1/4'' tapping bits, and those are not cheap.
2.) the device is slightly more expensive and heavier, but we have selectable clutch force , and a general chuck, good for any tools.
And of course they (impact drive vs. drill-drive) work in different way.
Which one is better ?
Regards,
Laci
If you are tapping a lot I would go for the first machine, but to be honest I would get some speedtaps and use a impact wrench as they are ten times faster- ruclips.net/video/96LwwycOhPI/видео.html
I have used these on site for tapping M12 holes in some 10mm thick plate and it taps the hole in seconds!
Thank you !
And no I don't need impact wrench, that would be overkill, I won't cut so big threads, but only 4...8mm. And its a big heavy machine. I ordered the DCF887 instead, thanks again.
Thanks for the comments ;-)
Power tap vs hand tap? Speed tap vs normal tap?
These questions are why A lot of us are even watching bud! Anyone care to elaborate?
It's normally down to time. If I'm at work and a machine has broken down it costs the firm money, the sooner it is fixed, the less money it costs them, so if possible I would use the drill to tap the holes.
Speed taps are brilliant for re-tapping holes in steel floor plates as you can do them very quickly and easily!
Obviously if you are making something for a critical application, you might want to tap it by hand, but in a lot of cases you can save a lot of time using a drill or impact driver.
Thanks for the comment
what drill bit should I use to tap for m4 bolt
3.3mm
There is a guide here- www.ultimatehandyman.co.uk/how-to/metalworking/tap-and-die
Thanks for the comment
More often than not you'll break the tap , It's really not something that is rushed
I have never broken a tap yet, although I tend to use Speedtaps in the impact wrench now- ruclips.net/video/96LwwycOhPI/видео.html
Thanks for the comment
subtract the pitch from the bolt size if metric hell of a lot easier
Stewart Holmes can you explain
that a bit more....sounds like a good tip
Excellent video. Cheers!
Gus Wilkens
You are welcome
Thanks for the comment
This method will help me.
Because I'm tired of tapping by hand everyday.
what size of tap for a M10 Hex Hd Bolt?
thanks in advance.
8.5mm but I would not recommend tapping holes that size unless your drill has a lot of torque. There is a guide here for drill sizes-
www.ultimatehandyman.co.uk/tap-and-die.html
I have cordless and 110v pistol gun. Ideally I would like to avoid tapping, but can't find fixings for job which has,added time to job
