New drill bit cuts square holes

[spinningmagnets]

Clever Japanese!...of course its not just the bit, theres an additional attachment that causes the chuck to move back and forth in sych with the odd-shaped bit. In the You-Tube, start at the 0:56 mark. That will give you a couple seconds of real-time, then it goes into a close-up of slow-motion...

This is not new! I witnessed this on my first job in a machine shop back in 1980's . I do not know the manufacture of this square hole drilling tool. I am certain that it was U.S.A. developed and made here. Non the less, way cool !!

Pardon me, I get upset on this not made in the U.S.A. stuff.

I like it thats a good product because usually a SQUARE hole has to be punched with a powerful punch press. I have some RAINJET sprinklers from the 1980's that will water a SQUARE area on your lawn but thay are no longer made because the plastic body of the sprinkler would split open after a year or two of use. finally i started to wrap the sprinkler body with goriller tape and this has worked so far. when thay are all gone i will be sad. anther good product bites the dust.

Some of the comments below the video are pretty funny :lol:

Very interesting! Wonder if they just take too long compared to a punch, or if the mechanisms are too expensive or fragile compared to a punch or similar device?

Thanks for sharing that!

Not sure this type device could be called a drill bit, can't be used in a hand-drill or even a drill-press.
I'd think it'd be a end-mill, used in a Knee mill, boring mill or something like that.
would be nice to have very small corner radius's without needing wire or electrode EDM.

Strangely that was my first thought. I didn't believe the Japanese invented it. Hmmm weird.

Franz Reuleaux- Berlin 1871

http://en.wikipedia.org/wiki/Reuleaux_triangle

Reuleaux was the appointed chairman of the German panel of judges for the Sixth World Industrial Fair opened in Philadelphia on May 10, 1876. He admitted that German-made goods were far inferior to those of other countries and that German industry's guiding principle was “billig und schlecht” (English: cheap and shoddy).

Apparently, the Watts Brothers Tool Works is still alive and well, near Pittsburgh, making bits for square, hexagonal, and octagonal holes. But they are also apparently one of the 0.01% of companies who don't yet have their own web pages. Maybe DiJet buys the setups from Watts Bros. and sticks their label on it.

I strongly agree that one should leave their nationalistic, religious, racist crap out of here. It serves no valid purpose, other than to showcase ones ignorance.

Hey folks here ! No pun intended with that statement. I was merely expressing my concern with the demise of U.S.A. manufacturing.
