Square Hole Drill Bit

I guess people can try and make a custom one for ww:

pretty cool ideas

I sorta doubt if that would have much application in woodworking. The motion of the cutter requires a serious clamp/holddown device, and I suspect that it would do more shredding than cutting in most wood. It might do ok in something like hard maple, but I doubt if it would do well in pine.

If this is a new design then it will take a little while before others can use the pat but once that happens I would imagine a lot of companies making these… Looks really neat.

I was thinking about possible use in M&T and/or square dowel joinery.

Hmmm … In one of the old Woodwright Shows that the Create channel was running this summer, Roy Underhill was using a manual device (can’t recall the name of it) that could actually create squares and well as diamonds and some other patterns. It was used for brass inlays.

Roy did a very ‘boring’ episode that shows it in use:

It is called a Passer Drill

Wow, that video is rather amazing. It sounds like that is also what cr1 is describing as well. I would never have thought that such a tool was invented that long ago. Thanks guys.

It’s stuff like that keeps me watching Roy Underhill’s shows … I’ll probably never use most of what he demonstrates, but I enjoy the historical perspective on the woodworking craft. Plus, I’m sort of a ‘keeper of odd knowledge’ (history major). It really gets deep when my brother-in-law (retired history professor) and I get together.

I see we have two threads of the same thing… pretty interesting but I wouldn’t hold my breath in the old woodshop just yet.

Mortise chisels make a square hole. Sum what limited on my mortise machine bud someone with a little machine shop ingenuity should be able to come up with a hand held version or at least one with more flexibility
