Drilling A Square Hole, MUST SEE

[JoeLee]

Has anyone here used one? I have a question. How do you "index"
the square?

Thats a good point. You would have to locate an edge of the cutter in relation to where you want your corners to be or no telling where your corners will end up.

Was everyone asleep?

There was a thread on this a month or so back!

well hes turning in his grave now that the chinese are selling them.

That's Dijet -- a Japanese company. Their headquarters is in Osaka.

[Toolguy]

I called them and tried to buy one. The person at Dijet told me they are only sold in Japan, not available here.

Look at this video to see how it is done. The cam rides in a form that establishes the path of the cutting edges.

Not the Watts method, but a method that is "inside out" from the Watts method. May be better, actually, since no guide is needed at the work.

The Watts has the shape of drill, but with a rounded corner. No cam, the cam IS the drill, turning in the guide which is the round piece inside the holder in the picture. Guide is harder than the hobs of H###

Drills a good enough hole for many things, including socket wrench square drives.

Turtle Creek was the home of George Westinghouse, at that time. Yeah, that Westinghouse. WABCO, or Westinghouse Air Brake Company. Back when great things were being built in the Steel City of Pittsburgh. I wonder if Mr. Watts worked for George. Keith

It figures that it was invented here and reinvented years later across the pond.

Used to be anytime this subject came up the guy from Slater tools showed up hawking his wares, but I have not seen an appearance from him in a long time.
