The Square Drill Bit

[Ryan]

Now this, my friends, is lunacy... Despite what the video says, this "drill bit" actually hails from Japan - not China....

That is very ingenious!

[Major Ramifications]

Pretty slick. I don't know if it would be worth the trouble, but it is clever.

Your point being? Some people haven't seen it yet, so let them enjoy.

How does something become older as something else?

Yeah!

In all seriousness... If it's old, it's old. I've never seen it... and it's my website, so deal with it you driveling swine!

Kidding again... of course... But I've always wanted to say that.

Anyhow, excuse my tardiness to the party.

That's really cool! I guess it uses the same principles as the rotary combustion engine.

[NASTYZEN]

I love things older than dirt. This one is darn impresive.

[aar0s]

any idea on where you could get one or how much they cost?

If you think that's neat, you need to check out How Round Is Your Circle?

I saw several videos of concept animations, but I hadn't seen one that looked like a shippable product.

I wonder how practical that is, it looks like it requires a special head on the spindle.

This is old technology, and Western, not Japanese or Chinese, as many of us here have posted. Search this forum or Google, but do your homework. You'll also learn the mathematical principles behind it, which will be worth the exercise.

I thought I was older than dirt and I'd never seen one before. Pretty cool.

why make square hole for round bolt??
haha seriously what would be the purpose? im just a mechanic so i cant think of anything i would use it for but would like to here what you would do with it??

[PT Doc]

Carriage bolt, no?

[PT Doc]

"hole" for toolbox drawers slides?

[Coach James]

I've never seen it before. Neither has my dad. My buddies at work have never seen it. Nor has my father in law. My wife and kids haven't seen it. My mom and sister have not seen it before either. The priest at my church said it's new to him. The guys in the Knights of Columbus said they had not seen it before. The autotech teachers at my school said they were not aware of this item. My secretary laughed when I asked her if she had seen a bit that drilled a square hole. The maintenance chief at the school thought I was joking when I told him about a bit that drilled square holes.

So a collective "Thanks" to Ryan for posting this from all of us that have never seen it before.

That concept design and product is called a Watts drill. A little pricey for the garage guy, but they can be had. Here is a Swiss made one for the mill: http://www.youtube.com/watch?NR=1&v=3n9kFqfmwoU

Also, for the lathe: http://www.youtube.com/watch?v=Acq7Vuy5wNc

Depending on the part and access to it, most large shops use large hydraulic punches to punch squares. They can also be made with plasma or waterjet. But you cant always access the part that way or punch an odd shape. So, for a small machine shop operation the above method is great. Also, with an undersized round hole drilled in the stock, a good patient craftsman can make a nice square using good quality files.

An arbor press and square cutting broaches that you press into your previously drilled round holes can make squares also.

That is just plain cool. I've heard of them before, but never seen one in action. I THINK the unit I heard about was used for wood, however.

I'm curious...I note the "arbor" ocillates heavily...does this require a special machine, or would it work in a large drill press? (Is "ocillate" the right word?)

Very impressive.
