I have been a qualified production engineer and I must confess I have never seen drill that drill square holes. Thank you for adding to my education. When people ask me how to drill a square hole in metal I will now tell them. All I knew about was mortisers for wood. And to think I used to bribe out holes in metal, drill in each corner and then use a file after drilling a larger hole second. Brilliant !
Hi Eddie thanks for your question, you are correct. The square size is dictated by the square so a 10mm requires a 10mm square die. The trick is the "floating" cutting tool needs one less cutting edge than the shape it is producing, in this case three cutting edges for four corners (square). If you Google "rotary broaching" you will find lots of examples. Thanks for your post.
I just finished building the handrail on my deck ruclips.net/user/postUgkxfQ5_mgwq6PcudJvAH25t-I4D-3cTPz4z and used this great little router to clean up the top rail before the final sanding and stain. It was light weight but packed lots of power. Either size battery didn't seem to make it top heavy and I'm a 64 yr old women so I really appreciated how easy it was to use...................... CORDLESS only way to go !!
This tool in this video is a Watts Drill Bit and floating chuck, using reuleaux triangle method, made by Watts Brothers Tool Works out of Wilmerding Pennsylvania. They do not have a web site nor a online brochure or catalog that i can find. If you would like contact them you must google the company name. Good luck!
The things are the bane of my existence. I’ve used them hundreds of times to put a “drive hole” into the end of a hardened worm gear. We buy the gears set worm & rings and modify them. I’d love to perform the op in an annealed state but it’s not feasible. The end is about 45 Rockwell hardness. We insert the worm into a fixture that has a guide plate over the end. The pilot hole size is critical to make the drill work hard enough to get into the corners. Alignment and squareness of the head, adequate thrust, feed, speed and flood coolant are imperative. The Watts drill typically lasts one to three parts before resharpening. The drill takes two months to obtain or factory resharpen so we do it in house much of the time. Once you start the operation you have very little control over size, taper and corner sharpness so you cross your fingers and pray. Whenever I can I try to use a rotary broach instead but sometimes it’s just not doable because of the extreme thrust that op requires exceeds capacity of my equipment on large holes.
My Mom was the book keeper and shipping department for Watts Brothers Tool Works in Wilmerding PA for 27 years starting in the early 1950's. Her boss, Charles Watts, was the son of the inventor of this technology. They held a patent on the invention, which, as demonstrated in the video, consisted of a floating chuck, a special drill bit and a guide plate. Their customers mainly were Ingersoll Rand and ship builders for the military who needed to make holes in steel plates that were too thick to broach or punch a hole through. The company is still alive today. Side story...one of my Mom's coworkers won lots of bar bets claiming he could drill a square hole. He carried a bar of soap, a small floating chuck, a guide plate and drill bit with him...turned the drill bit with his fingers and drilled a square hole in the bar of soap.
This looks like magic. Even though I watched an animation of how it works before I watched this video, my mind still couldn't comprehend how something spinning could drill a square hole.
Yeah, it would be great if one of those "ultra-slow-motion" RUclips channels could get this on video. Witchcraft should always be captures in ultra-slow-motion video. ;)
If you had known the Reuleaux triangle, it wouldn't have been a surprise: a triangle exists with equidistances along the lines perpendicular to its perimeter boundary...
Sorry for the slow reply. Great question, the cutting action is on the end of the drill and there is a starting hole so as long as the material to be cut isn't harder than the drill it shouldn't damage the drill. The drill floats on the x-y axis, the trick to the sharp corners is having on less cutting edges on the drill than corners required. Thanks for posting. Google rotary broaching.
Yes the process is the same but the die (or guide) is 6-sided. It is shown at the beginning of the video. Yes it will work on a blind hole but it does require a pilot hole. Thanks for your question.
The bit is not "floating" its pivoting on a cam system. It's not spinning in a concentric circle. It's being forced off axis to make square cuts. It's expensive but effective.
The short answer is it depends on how hard the material is, like any drill the harder the material being cut the shorter the time between sharpening. the pilot or guide is hardened steel. The setup in the video has been around and in use for years. Thanks for your question.
This is really interesting! I have a couple of quick questions. First, how come the guide doesn't quickly dull or damage the flutes on the bit? Second, Does the bit float anywhere along the x-y axis or does it move in a specific pattern? I would love to see a high speed slo-mo shot of the bit's motion. Anyway, really cool video, thanks for posting!!
This is a Reuleaux triangle. The only shape other than a circle that cannot fit through its own hole! Sandwiched between 2 plates it will roll completely smoothly, just like a circle. Quite amazing. Remember the Wankel rotary engine in the old Mazda RX-8? Yep, the 'piston' was a Reuleaux triangle. Make a manhole cover out of a Reuleaux triangle and it can't fall through its hole either! And you can use them to drill square holes. Or any even sided polygon hole. Quite amazing. The drill bit to do this was patented a century ago.
@@machiningmoments Thank you for the square hole demonstration. I've never actually seen it done, so very interesting. Something a person would think is impossible - a square drill bit!? Who woulda thunk it!
You are welcome. Although I'm told I sound like Jordan Peterson, I am not him. I wished I had his money though. ;) Thanks for watching and leaving a message.
75 years ago, when I was a lad, my father told me that ,in the machine shop of the shipyard where was manager he had a machine which drilled square holes. I was never sure if he was telling me the truth. Now I know - Thanks.
It would be great if one of those "ultra-slow-motion" RUclips channels could get this on video. Witchcraft activities should always be captures in ultra-slow-motion video. ;) Anyway, thank you so very much for this video and greetings from Portugal.
By using a cutting tool with one less cutting edge than the sides of a triangle (two cutting edges) an triangle shape can be made. You would need a triangle shaped guide. It can also be done by hand.
I'm wondering how the "guide" doesn't damage the bit (and vice-versa)? And what if I wanted to drill a piece of metal that's 1/2" wider or 1" taller -- doesn't seem like that jig would work...
I love the sentiment here but in our Engineer's heart of hearts we simply know we cannot truly call this drilling as it is not cutting the hole from single point of rotation.. I think you would actually call it offset broaching if you were honest with yourself. University of Wisconsin Platteville ME grad here, loving life as a project engineer sizing big-boy mechanical power transmission components. ..and no matter what an EE says, never run a VFD with a fluid coupling 😁 if you know you know!
The cutter is obviously hard or hardened material, as I would assume the guide. How does this not destroy the cutter since both have to be equally hard. Also, what were you using to hold the work piece stationary in the fixture
Amazing. I heard someone talking about this, and I thought they were joking. Your explanation of the process is perfect - easy to understand. So what is the square template/pattern made of - KRYPTONITE?
+Jon Lanier Like what? I want to drill a 1/4" square hole in mild steel that's about 5/8" thick. Slightly round corners Is not that big of a deal, I could use a file and maybe the square HSS tool blank to punch out square.
Great vid, thanks for posting! This is a nice tool! It will cut blind holes, a situation in which broaching is difficult at best! The pilot is hardened tool steel and the triangular drill is very likely high speed steel. The cutting edges of the drill contact the surfaces of the pilot during use. How fast does wear occur?
I've spent a working lifetime in engineering and have never come across or even heard of one of these before now. I'm seriously impressed, who manufactures them?
Can we drill a rectangle using an extended version of this drill? Like for exemple rectangle with width of 5 and height of 10 milimeters? Improvement to the current design would eliminate the guidance template if we can have a stable center guidance drill. This can be achieved if our main drill/milling drill have inside another drill decoupled?
Hola: esto es algo que parece novedoso, pero fue presentado en el año 1972, en la exposición de Fabricaciones de Maquinaria de Buenos Aires, donde se mostró una máquina que hacía agujeros cuadrados, triangulares, hexagonales etc.
Interesting, close but no cigar for me. That's got to cost quite a bit. I need four 1" square holes in 1/8 thick aluminum plate. Still hoping to find a die to place on a press, this is a great tool, just not practical to buy.
The " Square drill " have HSS or Carbide inserts only at the end. The edge further doesn't cut. It only strenghten the drill body, evacuate the chips and allow it to follow the square pattern. The square guide might be harder than the drill flute too.
I mean.. that's a cool little bit, but what do you do when your material you want to drill into doesn't fit in that little slot like that flat stock aluminum you used? I'm also curious how this thing does against steel and how long before your square guide starts to wear out?
The centre mass of the cuting end of the drill bit dances in a circle as if a man and a woman were waltzing and had a container of sand held between their chests, with a hole in it allowing a line of sand to describe an odd figure on the ground. You could rely on the might of a strong mill and strong tool steel to manage the off-centre mass or, and I think this is how the tool in the video did it, there is mass above the cutting tool that is positioned such that a little more mass is above where the missing flute of the cutter is. So basically you have a counter mass positioned to balance the shaft. Maybe the counter mass can be freely attached and centripetal force positions it where it needs to be. If anyone knows where I can find more info on the design of this tool I would appreciate it.
I've seen these before on YT, but never seen it being done "as it happens", and never held on of those cutting tools. Does the tool produce a specific size hole? So if you want a 10mm square hole, you but a 10mm tool, if you want a 12mm square hole, you buy a 12mm tool , etc etc?. Thanks for posting.
I’m sorry, even though I’m seeing it I still can’t comprehend what is happening here. But I don’t need to. I just need to find someone like this who understands it and pay them a small hefty sum of money to make my square holes.
If the drill binded to what it was drilling, could it then start to cut the template? I’m thinking that it doesn’t cut the template because it’s able to bounce off of it. Does it eventually make the drill dull where it touches the template?
Fantastic bit of kit. Is it as effective with steel? Can you give me the trade name of the jig and drill so I can get one please. Many thanks, Gordon, Australia
Been in engineering for years but never really believed you could drill a square hole.That is magic.

HOW TO MAKE A SQUARE HOLE:
Step 1. Start with a square hole
HOW TO MAKE THE FIRST SQUARE HOLE
What came first, the square hole or the drill bit?
Uh that's how tools are made dude. The first tool is always the hardest, and was hand-made.
you can broach the first square hole
***** I mean broaching the first hole for the guide since you wouldn't be able to drill a square hole with out it
I was one of your students at SAIT. Great video, you're a good man.
Same for me.
I wasn’t

@David-rx2to Thank you for this information David. I get a lot of questions about this really cool tool. That is a great bit of history!
IT GOES IN THE SQUARE HOLE
Best comment.. love to see her breakdown in the end. :-)
This looks like magic. Even though I watched an animation of how it works before I watched this video, my mind still couldn't comprehend how something spinning could drill a square hole.
Two things are happening, the drill has one less cutting edge than corners which forces it into the corners and the drive end is a floating eccentric.
So when the drill is cutting a corner, it isnt really spinning in one spot but it’s bouncing in and out of the corner?
Yeah, it would be great if one of those "ultra-slow-motion" RUclips channels could get this on video.
Witchcraft should always be captures in ultra-slow-motion video. ;)
this proces should actually be made in one of those slowmotion 3D animation
If you had known the Reuleaux triangle, it wouldn't have been a surprise: a triangle exists with equidistances along the lines perpendicular to its perimeter boundary...
So how was the first square hole created before you had a square hole to create the square hole.
In the fixture? Likely machined, hardened, and ground.
Just like your sense of sarcasm lol
this guy..
chisel
There are many ways to create a square hole, wire or spark erosion for instance
I knew these existed, but for most of my life, I thought they were a novelty, I had no idea you could actually buy one! NEat!
These are great. We used one for 3" square holes. Chief brought the set out of his office. Love to get one now.
They are handy for jobs such as your use.

Yes, the drill is mounted on a morse taper so it will fit in the tailstock of most lathes. You would need to adapt the die to your headstock/chuck.

Glad you liked it, thank you for posting.
You would need to adapt the fixture to the panel, maybe clamp the fixture to the panel. If you need a larger square you would need a larger die.
Would be fun to see a slow motion video of the process. I have some imagination how it might work, but I'm not fully certain.
That is a great idea. I'll try it next time I video it.
This is really cool! Never seen anything like it.
It's different, kind of neat! Glad you liked it, thanks for saying so.
still has rounded corners. Is this set up worth all the time? Seems other methods would be quicker.
+Jon Lanier One of several options I guess it depends on quantity required, broaching, EDM, or a punch press may give you nicer corners.
+Jon Lanier Like what? I want to drill a 1/4" square hole in mild steel that's about 5/8" thick. Slightly round corners Is not that big of a deal, I could use a file and maybe the square HSS tool blank to punch out square.

The guide controls the shape. So I think if you had a rectangular shaped die (template) and the drill had enough travel off of center, it would work.
No you cannot drill a rectangle with this tooling. All sides of the square, hex, octagon, pentagon, or triangle must be the same length.
wow that's really cool

Why didn't the three lobe bit also cut some of the "guide" ??? or at least mess up the "square" ??
The guide is made of hardened steel. It is harder than the drill.

Yes it is neat to see but not for everyone. Thanks for watching. Good luck with the holes.
If he can do this type of magic, I betcha he can drill a hole without using a drill a well.
Why does it not also eat into the square guide as it turns?
The " Square drill " have HSS or Carbide inserts only at the end. The edge further doesn't cut. It only strenghten the drill body, evacuate the chips and allow it to follow the square pattern. The square guide might be harder than the drill flute too.
Interesting. I'm wondering if you still get a radius on the corners of the hole though, I couldn't tell in the video.
There will be a small radius in the corner.
I mean.. that's a cool little bit, but what do you do when your material you want to drill into doesn't fit in that little slot like that flat stock aluminum you used?
I'm also curious how this thing does against steel and how long before your square guide starts to wear out?
You would need to adapt the jig to suit your scenario.
It goes in the square hole!
Yes it does :) Thanks for watching.

I’m sorry, even though I’m seeing it I still can’t comprehend what is happening here. But I don’t need to. I just need to find someone like this who understands it and pay them a small hefty sum of money to make my square holes.
I'm available! :)
That's pretty awesome!
It is! Thanks

Amazing.
what keeps the bit from eating the template?
The template is hardened.
magic
If the drill binded to what it was drilling, could it then start to cut the template? I’m thinking that it doesn’t cut the template because it’s able to bounce off of it. Does it eventually make the drill dull where it touches the template?
Sorry, just realized the clamp was part of the fixture.
Fantastic bit of kit. Is it as effective with steel? Can you give me the trade name of the jig and drill so I can get one please. Many thanks, Gordon, Australia
