    YouTube might have something to help, can you drill the hole deeper to allow you to use a square broach. They look to be pricey, but maybe someone here could lend you one?

    Not sure, but broaching might be something @doubleboost has covered in one of his SSS video's?? :dontknow:

    i could drill the hole deeper yes sure. Can I not just use a thin milling cutter and take the corners off

    Was that what you were trying when you snapped that milling cutter previously? What diameter of cutter would you end up using? As long as the cutter you have has sufficient length on the flutes you probably could. but the 'slot' will always be rounded on the corners, of course.

    No I was milling down large T nut the cutter snapped because it came loose due to me not having a spanner to tighten the arbour. I would use the thinnest cutter I have I guess 4 or 6mm, a slight rounding in the corners should be ok I am making a handle for the machine vice

    Creates a wobble. Much like wiggling a drill with a blunt holesaw to rotate what corner the broach cuts on

    Mines a through hole. No reason it needs to be blind

    no it does not need to be blind at all. I can easily make it a through hole then square it off
