How to cut and thread steel conduit

- How to cut and thread steel conduit easily and quickly. Steel conduit in the UK is often found in 20mm and 25mm diameter, which can be galvanised or painted black. In order to fix boxes to the conduit, it is necessary to thread the end using a stock and die of the correct thread. Normally conduit threads are metric, whereas pipe fittings for steel pipe are Imperial sizes.

You make me want to buy tools I don't need :D
I do apologise 🤩
Thanks for the comment 👍
@@ultimatehandyman I must say, I bought one of them Bahco mini socket tool sets you appraised and fitted it under my motorcycle seat for our recent tour of Germany etc. One of the riders in our group had a leaking clutch cylinder on the second day and that tool set was perfect for the job of bleeding the system and topping up the fluid. We had to use it every day too so it was worth every penny. Thanks very much :)
That Bahco socket set is one of my favourite tools, it is mega useful for some jobs and well worth having one!
I'm glad that you found yours so useful 👍
Ha Ha me too
This was a nice and easy video to make, which is a real change after some of the tap changing videos- which have taken hours to film and days to edit!
I hope everyone has a great Sunday (it’s a bit wet here) 🤩
Thanks for the video, always top notch instruction,as usual, wet here too in w,yorks, absolutely hammered it down last night. Hope your keeping well ,regards to you and your's. Stuart
@@stuartlockwood9645 It's put some rain down here over the last couple of days! I'm great, thanks ;-)

Another one who thought about Trefolex when I saw this, and being an apprentice.
Threading conduit's a useful thing to know how to do.
Shows it well in the vid. Cheers
It's weird how some Trefolex appeared in the workshop on site last week and now a couple of people have mentioned it 😀

Good to see your channel growing,your help me out a few times thanks man 👍🏼🏴
You are welcome

I've seen an old school sparky thread a pipe in a rush with a hacksaw blade, twas impressive!
How long did it take him?
Thanks for the comment 👍
@@ultimatehandyman can't say for sure as it was a good few years ago but I'd hazard a guess at about 10 minutes with a good bit of sweating!
Thanks for the reply ;-)
Takes me back to the days of installing LCS pipe. That was hard work! Great video!
Thanks 👍
I do a lot more pipework than conduit, when I'm on site.
I enjoy cutting and threading pipe, some of my fondest memories of working on site are when I was installing compressed air pipes with big John (R.I.P) a few years back.

Ultimate Handyman RIP to your friend.
Mr Ultimate Handyman- thank you for you great tips. Highly appreciated mate.
You are welcome
Thanks for the comment 👍
My wife: why haven't you done the washing up?
Me: I was learning how to thread conduit, ready for the zombie apocalypse
LOL
Thanks for the comment 👍
Great tutorial as usual 👍🏻 maybe show bending conduit with that vice.
I'm not sure if I can use it as a bender, due to the position of the steel cupboard at the side of my bench. I'll give it a go, when I get chance ;-)
Thanks for the comment 👍
Top!
good information
congrats!
Excellent!
It's a very useful instructions. Thanks so much.
You are welcome

Yeehaa !
It’s Sunday.
Time for another Great video, thanks for sharing.

You are welcome Ash, Thanks for the comment 👍
Great vidoe . As always Chaz .☕
Thanks for the comment 👍
found this video very informative and useful.
Thanks for the comment 👍
I get a lot out of your videos, even here in the US. Our conduit's wall are really too thin to successfully cut threads into. For your information. Thank you once again.
Thanks for watching the videos ;-)
If I visit the US in future I'm looking forwards to seeing how things are done over there, as they are so different to over here!
Thanks for the comment 👍
No we have EMT (the thin walled) you can't thread, BUT THE IMC AND RMC (intermediate and rigid conduits) YOU MUST thread, that's a big portion of what electricians do in big commercial jobs here in the US.
I was always taught to cut the first couple of threads dry, then remove the dies and add the cutting compound to cut the rest of the threads. Helps the dies 'bite' at the beginning
The die will bite regardless, but it's better to protect your investment by ensuring the dies are lubricated.
Thanks for the comment 👍
Yea gods this takes me back to my time as an apprentice, I remember we used Trefolex for cutting paste, horrible green stuff it was.
I'm sure we have a tine of that in the tool store at work ;-)
Thanks for the comment 👍
Great video , Good entertainment, thanks , Keep em coming
Thanks for the comment 👍
Well explained video - you would make a good teacher at technical college if you decide on a career change 👍
Thanks for the comment 👍
This is very nice!

Looks cool.

Great video. It will help me put up my outdoor light but I don't know how to install a fused spur. Any tips?
This might help- ruclips.net/video/47fkKdBjqvI/видео.html

Is your pipe vice also a bender? I noticed it had roller guides, I've never seen one like that before. I've got an old Record 92 pipe vice.
I think you can use it for bending, but I've not tried it yet.
I bought it at auction a few years back and only fixed it to the bench last week- when I needed to thread the conduit.
Thanks for the comment 👍
Fair play mate, you are probably more skilled than a lot of sparkies I've worked with in my time. This type of work is my bread and butter. It's comical seeing a Billy Bullshitter realising he's going to get found out when you get the conduit bender out 🤣. There's no shame in not being able to do it as a Spark. Everyone has strengths in different areas of electrical work. If i went to work with house bashers, they'd think I was shit because i can't lift carpets and floorboards.Galv Containment is like the ultimate bragging right, though, for some reason 🤦.
Thanks 👍
To be honest, I rarely install conduit. I’m more of a pipe installer and have done tons of steel pipe from ½ inch up to 2 inch threaded. I’ve bent plenty of pipe using a hand operated, hydraulic bender, which will do up to 3 inch.
Thanks for the comment 👍
That’s great - thanks.
Thanks for the comment 👍
Nice video. Quick question, would that pipe cutter work on stainless hydraulic / seamless tubing?
It should do. I use a similar cutter at work to cut stainless pipe from 1/2 inch up to 2 inches in diameter. Obviously cutting fluid/coolant is essential.
Thanks for the comment
awesome!!
Thanks for the comment 👍
Thanks. Is conduit for protecting wires? And is that tapered thread like on water pipe?
Yes, the conduit protects the wires. Normally if a socket was being installed in a factory etc. the conduit would be installed and single electric wires would be used (singles) instead of twin core and earth (which is used in most houses).
The threads on conduit are parallel, unlike pipe threads, which are tapered.
Thanks for the comment 👍
Real good!
Thanks 👍
Wow, this vid took me back !! In the early eighties I spent 6 years as an apprentice electrician learning to cut , thread and bend tube !! It reminded me of a job I once worked on, a prison in Banstead, Surrey, we left our tools out over night knowing they would be safe, security was tight even though there were no prisoners as yet, the building had been used as an asylum I think, anyway when we came in in the morning the guard dogs had eaten all our tallow fat that we used to cut the treads !! lol. Oh, and not to be pedantic but its a coupler not a connector , sorry for being an arse !! Thanks for the trip down memory lane, I always enjoy your videos !!
I struggled calling it a connector, I normally install pipe and to me it is a socket ;-)
Thanks for the comment 👍
would a angle grinder with a metal cutting disc be good for cutting the pipe
Not really! It would easily cut it, but galvanised steel can give off fumes, which can be harmful, so it's best to use a hacksaw or a steel pipe cutter.
Thanks for the comment 👍
is there a threader for threading INSIDE the conduit? If yes, what's the brand name? I intend to use it in building bottom brackets and head tubes of bicycles. Because of the pandemic, bikes became very popular. So now it's hard to find old frames in my country where I can just cut off the bottom bracket and head tube of old frames, So I'm thinking of making my own bottom bracket and head tube. I know a metal lathe would do the trick, but I don't have space for a metal lathe,
I guess you could just use a tap and die, to thread it internally. That is providing you can get the correct size tap for the internal diameter of the tube
great video, do you know where can i buy that type of threader?
You can buy them at most electrical wholesalers, or you can get them from eBay etc- fave.co/3pOVnfE
hi great vid . Any links to the pipe cutters used or alternative which will cut conduit. Many thanks
One of these should will cut conduit- fave.co/32mstES
Or they sell smaller ones, but I'm not sure how effective they are- fave.co/2zOJjQi
Thanks for the comment
@@ultimatehandyman would this be suitable?

Not sure, I have one similar to that, but it can only be used to cut copper pipe.
Pllease can I hv the link where to purchase the Tap and Die set for 20mm and 25mm
I bought mine from eBay- fave.co/3erX8I0

Can I use ½ iron water pipe instead of the pirposely made conduit pipe?
I got a lot of fittings and pipe left from previous plumbing jobs.
You could do, but you would have to use pipe fittings instead of conduit fittings. In the UK conduit and fittings are metric, whilst steel pipe is still Imperial 👍
@@ultimatehandyman Thank you for the reply!
Ah ok t , the intersection box has metric thread so It's going to be a mish-mash of imperial and metric perfect for the next guy who has to deal with it (Me).
After that can you connect that with a metal junction?
I used this to install a metal clad socket- ruclips.net/video/iBdkNxYtrEY/видео.html
But you can get lots of accessories that fit the conduit- bit.ly/2IwqitA

which is the best size conduit to run compressed air lines, 9 bar
You need steel pipe for that, not conduit.
Conduit is only suitable for protecting electrical cables from damage.
Thanks for the comment
Is there an alternative to cutting paste? I need to do one job at home and don’t want a whole tin of the stuff
A bit of oil will be fine, just make sure you wipe it off afterwards
Thanks for the comment 👍
@@ultimatehandyman thank you for the reply 👍
can you cut solid round
bar with that tool ?
I’ve never tried, but I think it will damage the cutting wheels. We use them on site for cutting steel pipe up to about 3 inch diameter and 6mm wall thickness
Thanks for the comment
No
Hi pls where did you by yr vice from?
I bought it at auction a few years back from bidspotter.co.uk
I've not seen any for sale since, I did have three of them at one point, as I was bidding on three of them and won them all, but I only have the one that is fixed to the bench now. You can get them on ebay but they are not cheap- fave.co/3iqa8PL
Thanks for the comment
So the pipe is held down by a piece of chain?
Yes, it is a Chan vice. It's not a normal piece of chain, it has longer rivets that stick out at each side of the chain, they engage with slots in the vice, you then tighten the handle and it pulls the chain tight- which is great for gripping round objects.
Thanks for the comment 👍
@@ultimatehandyman there must be other ways of clamping round stock, such as a Workmate with a double V-groove?
That might work, but I’ve never tried it.
Conduit is actually properly sold in 3.75m lengths - not 3m.

Those prices for hiring are insane. 40 for one day??
Yes, but often these would be hired by electrical contracting firms, so the price will be added to the job. It's much cheaper if you hire them for a week etc.
Thanks for the comment 👍
By a contracting firm? If you would do this often (as I expect a firm to do), wouldn't it be logical to buy your own? I mean, there's also competition there, so you'd be cheaper
I don't own an electrical contracting firm, all I know is that some firms hire in equipment. As you can see from the video, I have my own stock and die set.
If people did not hire the equipment, the hire shops would not stock them.
can this be better? no :)
