How to drill a square hole [in wood]
 

Someone posted this on Imgur: https://i.imgur.com/zPh341R.mp4

I don't know how to make MP4s or GIFVs work here and they did not link the source.

Have a low-quality GIF!
No no no, that isn't animated and not only did the poser not pose a source, but the square video is 9x16 for no reason!

I couldn't find another version, so I used Vance to enlarge (and enhance) and cropped it:

Of course, the forums shrank it.

So, it shows the squircle rotating inside the square, shows a laser cutting flutes in each side, slightly beveling the tip, and shows it being attached to a shaft and drilled into wood, leaving... a squarer squircle.

This isn't the source, but it is similar: https://www.youtube.com/watch?v=L5AzbDJ7KYI One or two people shared this: https://www.youtube.com/watch?v=rjckF0-VeGI Is that the same concept? I don't know, he never once mentioned "Squircle!"

Of course, once they made the flutes it wasn't a squircle anymore, it is a 3-sided drill bit--in a square collar, which doesn't wear out?

Of course, even I knew about mortise bits! https://www.youtube.com/watch?v=rjckF0-VeGI I just didn't know their name, but that was the first result when I searched for "How to drill a square hole."

Edit! Two of those don't show up here, so I am trying to find something similar--and hoping they show up here.

This guy tries to make his own bit, which wasn't perfect, and he said said he could improve it further: https://www.youtube.com/watch?v=8mscZEe7vr0 He talks kind of funny, so I needed to read the subtitles. This guy used $20,000 worth of equipment to cut a slot in a rod, pin a piece to close in the open side, and then trim it down to have a square hole.

Should I have specified wood? :)

I don't even understand. He milled a tapered square end, which put corners on a round hole?! https://www.youtube.com/watch?v=DgB1psCFC7o Also, he has a special machine that looks like a scroll saw with a square file instead of a blade.

This guy showed how to file by hand, use a machine he made, a mill to make a squircle, and then he makes a tapered square end like Tony, but tempers it, grinds a concave face, and uses it to chip away at corners of a round hole. Then he uses a bunch of equipment to put corners on a round hole: https://www.youtube.com/watch?v=ASz-Ayo6-xM this is AvE, but before he was cool? https://www.youtube.com/watch?v=M3Ul-s9_MA0&t=0s This one seems like it requires the least expensive equipment, he put a square file in an arbor press and squared a round hole: https://youtu.be/wpD_3UJXzSI?t=27 Are vastly more people putting square holes in metal than in wood?! :)

Made me look. :)

I don't know how to put this.
But a squircle doesn't have flat sides.

I finally finished adding videos. For some reason the previews weren't showing up at all until I posted, so I posted one video at a time.

The last video, which is short, has a still of a VW work truck!

I have used a square hole drill for wood and it didn't look anything like that.

Once you see them you can't unsee them. A squircle for comparison:

No flat anything.

A mortise bit?Did Apple patent squircles?

Once again, two different things.

A Squircle is a continuous curve.

Are you claiming this isn't a squircle?!

Well?!

I don't care to [continue trying to] explain it, let's ask Wikipedia:

It has three sides!

Kin ye nae count?! :)
