The Largest Drill Thread We've Machined in 60 Years (It's Literally Off The Charts!) 

Just discovered your channel. Great machining stuff. Don't let anyone turn you down by comparing to another channels like Bomber from Florida, Cutter from Australia, Infinite Precision Man from Germany. Remember it's your channel, your shop, your rules. We like them because they are different and you should be yourself too. All the best and keep up the good work.

First time watching your channel, Awesome work! I´m an Industrial engineer from El Salvador, trying to expand my knowledge in machining and channels likes Kurtis and yours are a god send for that purpose. Keep it up, I´ll be waiting for more videos.

Ah yes, the forbidden pink lemonade 👌🏻

I thought it would be boring, turned out to be nuts.

Kong is big but I hate to tell you, Kurtis from Down Under at Cutting Edge Engineering has it beat by 3 miles. . Specifically, it weights 209.5 lbs or 95 Kilo's and is 125 MM (4.9 inch) bar and 1100 MM long (3.6 Ft) with 900 MM (2.9Ft) of reach. . It's King Kong of boring bars. . Has to use an overhead crane to get it off the floor. . It's so big it's funny.

I've machined 8" Drill Joints years ago, But nothing close to that beast ! 👏👏👏

Talk to you regularly great to see my tooling working

People always are shocked by the big stuff. I’ve only ever worked in a heavy machining shop so an M580 nut (a samllish for us) isn’t really that big. Great video. Love a shop made tool also.

Looks beautiful. So very shiny. Can't wait to see part 2 for the other part. . very exciting.

Don't be running yourself down m8, from what I see you're doing fantastic work with the machinery you have.

I recall as a kid watching my Dad cut 7/8 14 tpi for an old Allis Chalmers Combine. To go next size up cause 3/4 was chewed up. soooo long ago. Thank You for keeping the craft up and running 😉👍❤️

Thank you for the video and explanation 👍

"now we gotta cut 30 more of them" 🤣

Cool stuff. Definitely subbed.

Hey dude new subscriber here. Gotta say I really enjoy your content and seeing someone passionate sharing makes it even better. It’s nice to see all the machine work in Australia like cutting edge engineering if you heard of him. Keep up the good work Best regards from Switzerland

Nice work brother !!

I did my Apprenticeship in a Shaft Shop. All we made All Day was Shafts ??? ( what are we making today ??? ) IF you can Turn It. We made or repaired it. The business had it's 100 year anniversary when I was working there. When I first started working there we had a joke running where was most of the Rain ? Outside or Inside the factory 🙄 Not only that to deal with, the floor had large pieces of timber covering the huge pits where the Flat Belts ran the earlier machines. The positive of that was, when it Rained the pits would fill up with water ?? The place was huge and so were the Holes in the Roof and Floor ??? Thankfully after I started there with 4 other Apprentices the indoor swimming pools were finally filled in with concrete and they replaced the Hole Roof. The Old Tradesmen all hated us, because we made the place too comfortable. ( their words, lol ) Adding to that we were the first Apprentices to be hired by this company. The Lady who pushed us into this place was so proud of herself for what she accomplished ??? We only found out about the thing with the first Apprentices in the lunch room about 2 weeks after we started. Trying to find a way to stir up the Tradesmen ( as Apprentices are only good for ?? ) One of the Apprentices called out to the Tradesmen asking ... Have you ever had any Apprentices working here ? The Old Tradesmen started laughing and replied.. Don't wantem and don't need em. The Apprentice who asked the question only lasted till the end of the first month because the Trades wouldn't teach us anything. We were only the go for boys ( go for this, go for that or maybe hold this ?? ) Thankfully the same week as the other Apprentice left they suddenly started teaching us everything. They were Amazing to work with after that first month. We all learnt So Much from these guys. It was a tough job. We learnt the hard way to do it the easy way. ( something they always, kept telling us ) Apologizes for the Long Comment. I just wanted to highlight the Tradesmen who not only taught us Skills. But how to become Men too👍👍

Love the videos, not to many ads, so i watch till the end, Not GREEDY LIKE SOME. no bullshit just great content. Thanks. Look forward to next week.

You make excellent videos.

Just gotta love the incanink! Lotsa talented people out there. Some are really good when it comes to offering up sound advice. Yeah big stuff always attracts interest. Interesting vid. Don't see a lot of Aussie stuff, so all good. In small scale manufacturing myself, but vastly different field.

loving this, cheers from the other Sunshine State, Florida USA...Paulie

Excellent vid bro

I machined part of the Large Hadron Collider. Eight metre long six hundred millimetre tubes in stainless steel.

The only thread I know of that is larger is 8” and 10” BECO thread; they can be cut as 273mm or 343mm O.D. Invented by Bucyrus for blast hole drilling rods. I manufacturer these rods for larger diameter DTH drills. The only other place I’ve seen them used are on Atlas Copco/Epiroc Pit Viper drills. I have custom inserts made to the thread form.

Lovely video

Good intro🎉

Im an auto spark and did a few rewires on drills over the years. The size of the gear on some of the rigs blew my mind. I cant even imagine the rig thats gonna run that

That's insane

Hi Great video, be great to see a wider shot of the machine included whilst its machining. It looks like a Harrison alpha. I bought my first Alpha in 1996 an Alpha 400 so just a small shop lathe with a 55mm spindle bore. Loved that machine, ran it for 10 years and had to part with it sadly. ventually bought another secomd hand 1997 model i rebuilt in 2012 and use hard every day , great for one offs and repair work as you get best of both worlds with manual/cnc combined. look forward to seeing more great content from you

Nice thread, seems a good surface finish, I have now only a 4" lathe. I do boring bars on the opposite site, so the insert faces down. doing it that way, my maschine tends to spiraling and blocking. Biggest i made with this lathe was 60 mm dia, 0.5mm per rev. (around 2 1/2", 0,02" per rev) in early 80 i made a screw, used as pylon with 3.5m dia and 25m long.. 6m thread lenght, pitch 4 inches. 40 tons if i remember correct. took an whole day for fit testing the nut. but it fits smooth :-)

Hi Mate, I did my apprenticeship and worked as a 1st class Machinist at Boart Longyear in Adelaide during the late 80's and throughout the 90's/2000's and cut some pretty big threads especially API threads! Why do people call your coolant the forbidden pink lemonade?

Very nice! I still use a lot of top notch style tools.

Great vid, it really does make 8 1/2-inch Reg look so small and next is the pin 😀. I had a laugh😆 about the comments on the size of Kong and Curti's boring bar, everything is relative to the size of the lathe you have and the work you perform. Where I work our largest boring bar is a Sandvik anti vibe bar and it is 200mm (8 inch) in diameter and has a max working length of 2 meters (79 inches) and that doesn't include the rest of the bar held in the tool holder mounted on the cross slide, so that makes it over 3 meters long and it's still not long enough as we have to turn the component around and bore it from the other side as well.

what loads are calculated for drill string using this coupler -compression and tension?

Thanks for a great video . Is that a Colchester lathe ?

Bore / Core sampling very deep , outer being's would use larger on scale , keep up the good work

Love that Kong boring bar..........

Always a good rule of thumb to bring your hand or some similar into the shot to scale size of the stock

Impressive!!! I do some small manual turning once in a while for maintenance/repair at work. Small question, why not modify Kong to have thru coolant? It may be a wee challenge, but well worth it in the long run.

the lathe behind you,not the one you used for the screw thread . is it a Harrison ?

OMG - That's how Slinkys are made!

when you mention the expected torque for the drilling. How much do you expect it to be?

Hi ,you make nice content, however , i was wondering how do you measure this internal thread ? Do you have a thread gauge or something ? I do some thread milling , like a M162 x 3 or M 184 x 3 ,but at first i make a gauge witch i can meassure with 3 wire measurement to see if the pitch diameter is within tolerance , and then i make the internal thread to slight oversize so it will fit any part of that size any time .

This is pretty cool. There is no API standard for that thread I would assume. (is there a world standard, DIN I suppose, now for drill threads?) I am also going out on a limb and say it was engineered along those lines, however I didn't notice much taper. . I am an former water well driller and we usually used threaded connections around the 3" range. We did have a few tools that subbed on to the drill stem with the 8 5/8 thread and it was pretty large stuff especially for our application. thus seldom used. Looking forward to the pin. Cheers from the Northeast USA.

Think so... anything bigger is likely casing. A go/no-go gauge for this set in the works? Sooner or later, inspection arrives.

what is that pinkie juice . :D its like from different world

Didn't see you gauge those threads.....must've been too busy watching the pretty pink coolant

Kong is incredible

How do you know what size the pitch diameter is? Do you just cut the male thread to fit? I thought I heard you say 30 pcs? Are they interchangeable?

Ground up the Pink panther. LOL.

that answered a question; can you alter the spindle speed to maintain the surface speed (and therefore finish) when taking facing cuts *(hears motor spooling up as it makes the cut)* apparently you can.

One question. Why no through cooling in Kong? Btw if you can prevent or have a guy with some fire suppression gear ready at the machine. Then nothing beats running straight up oil ( like the strub's vulcan futura cf2915 ) and run it as a as close to room temp as possible would be optimal ( witch can easily be done by running it through a normal pc/car radiator/ condenser with a fan taped to it before going through the nosel out to the part. We did it and it worked surprisingly well )

What is TPI and TPF? Is profile similar to API Regular or Int. Flush? I've cut more than a few (hundred) tubing and casing threads, and many of the Spec 7 (API) tool joints, and there are casing buttresses that are quite a bit bigger, but I think you've got the world beat in tool joints. I'm curious what you're doing about gaging?

Channelling Crocodile Dundee? That's not a thread, this is a thread

Love these channels also watch CEE , keep it up

You’re great on camera

My heaviest cut I have ever made was 10 mm in steel but only a feed rate of 0.07mm I got so many burns from that since we are running normal lathes and using a dnmg style insert

have look at Cutting Edge Engineering for his "Large custom made boring bar"

Biggest in the world? What about the drill pipes used on the Glomar Explorer, the ship that raised part of a Russian submarine?

How do you check fit the thread? I'm guessing you check it in the set-up and use a custom gauge and I'm guessing your shop made the gauge.

As a tool and diemaker, I love watching how this heavy work is done. Much of my work had to be verified to ensure the part was within specification. In this case(huge internal thread), how would you verify the threads you have cut? Do you have a part that you can test the thread fit against or a Go/No-Go gage? How do you measure the pitch diameter? Love the videos.

WoW!!!!!!

12:03 Slinky!

You ought to get together with Kurtis from Cutting Edge Enginneering - that would be some real fabrication porn !!

Nice vid. If im not wrong you make 55 or 60 deg threads. Have you considered trapezoid or round threads for those high torque connections?

What was that he was talking about the nose radius of the finishing cut? Junior machinist here.

The biggest threaded joints I heard of were on Howard Hughes ship Glomar Explorer

A 3 metre hole 250mm deep, from the back of a Truck! What ( material) are you drilling into?

Are you able to share what material if is? Pretty please :)

Just a quick question, what happens to all of that coolant? Does it get recycled somehow?

I used to make videos for commercial equipment, you have way too many scene change’s and fades, the thread cutting section was quite good in fact the best part of your video as far as watch ability goes. Take your time with camera movements, nothing turns people off faster than quick shots as it gives them a headache trying to follow the view. Get a camera tripod for some of the shots it will allow stability and help greatly with close ups. Don’t zoom too much as you can overdo it. I see you follow CEE so pay attention to Karens work and how she films Kurtis at work, she is getting very good and her editing is great. I’ll wait and watch a few more of your videos before subscribing. Cheers.

So, are you doing a complete drill string in this diameter and, can you share why you are drilling a 3m hole 250m deep? Surely not to cut up into shorter lengths and sell off for underground tanks or the like🤔🤣

Amazing

👍

If you designed it you get to give it a name. How about HALxxx where xxx is the diameter of the connection

OK, who else had the Pink Panther theme music start playing in their mind at 5:18 ? damnit *>_

CNC you will never be a CEE LoL

I had to go double check the hole size that the drill will be drilling. 3m diameter by 250mm deep ( 0:55 ). Is that actually a footing for something? At 250mm deep it's barely what I'd call a hole. I checked the description and the description says 250m which IS a hole.

How big is the thread gauge 😂😂

What do you mean you wanted a left hand thread? Oops.

like to see real life vid of where these go, dont really get ascale of how big these are, could you show next to say a hand/foot/ bear can 😜

Would have liked to see you gauge it......

I am not machinist, true to say, a medical. Nice chips but is it OK with the chip color. I thought inserts are burning.

Hi, new viewer here, but after 5min…. I subscribed. 👍 Personal question. Where’s your accent from? Seems too soft for a native Q’lander. Anyway, looking forward to your uploads. 👍

4mm pitch?

It would’ve been nice if you would’ve told us how big it was.

We have been running 36" drill bits since the 1970's...

I assume that gets welded to something?

Brilliant problem solving safely ❤❤❤on the job. Should be part of education worldwide #MHLivingHistoryLeapyear2024

3 metres wide by 250 mil deep.... Not millimetres, I guess..

I like your videos but PLEASE: stop with the quick cuts, and stop waving the camera like you're trying to swat flies with it. Those camera moves are OK when the content is boring so the camera operator tries to create drama by moving the camera. Your content is fascinating, please let us enjoy it without all the camera movement.

He's got 40 something but he hasn't do this job in 60....numbers doesn't match here

Couldn't watch the video. Sorry. Too much movement of the camera, zooming and cutting to different views. And all the talk of dimensions in mumblemeters means nothing to those of us who use bleems and bananas as our measuring system.

boring, boring, boring, & annoying
