    Looks pretty neat, not sure how often you need a square hole though....

    Here's something that should be really useful though!

    Oh... I didn't know how much I could drool...

    Wonder if can think of a reason I need to drill a square hole... Runs off to make a square peg

    As a side note... I think I need help
    You only need two tools in life:
    Duct tape if it moves and it shouldn't.
    WD-40 if it doesn't move and it should.


    Brute force and ignorance always prevails.
    Failure comes from too little brute force, or
    too little ignorance.

    Dad used to have a drill that drilled square holes in wood about 40 years ago. It had a square shroud in a square shape that went around the drill bit. The shroud was more like a chisel and the drill bit only took away the cuttings and the centre of the hole.

    That's called a Mortice Chisel and you can still buy them, FWIW.

    That's pretty smart. Kinda reminds me of a rotary engine

    I'd imagine a square hole wouldn't handle stress as well as a round one, no? See: Comet air disaster (metal fatigue).
