Japanese drill bit creates square holes

The YouTube caption: "Amazing — but from the sound of the impacting cut, I'd bet the mill head is short lived. It can't plunge that fast and needs to be roughed out first. If the corner radius is less than 0.0625 and greater than 0.500 deep, then I bet this application would work pretty well."

Note added at 5:18 p.m. today: The original post read "Chinese drill bit...," as does the title of the YouTube video. Reader Chuck K. commented, "You know it's all Japanese, right?" I do now.

Googling Dijet Industrial Co. Ltd.  — the company whose name appears at the beginning of the video — yields the company's homepage as the first result; upon visiting, one learns the head office is in Osaka, Japan.

Shame on me.

This is sad Joes.

They do make Mortise Bits for drill presses...probably only works on wood where this seems a little more versatile.

My luck for forwarding it too quickly.

I was amazed at the shine more than substance.

Thanks for the correction.

Oy. I didn't know that when I created the post but I do now. Chuck, Thanks VERY MUCH for the heads-up. I will correct the post and add a note to that effect.

What's really sad is that I lived in Japan for nine months and spoke and read enough to get around.
