The most common way to fasten the arbor in the milling machine spindle is to use a draw bar. The bar threads into the taper shank of the arbor to draw the taper into the spindle and hold it in place. Arbors secured in this manner are removed by backing out the draw bar and tapping the end of the bar to loosen the taper.

Making a square broach to fit in the mill spindle might be a way to approach the square corners. A piece of 1/2" drill rod, for example, milled to a square shape on one end and then hardened could be used in the mill spindle as a broaching tool moving the spindle up and down by hand while feeding the X and Y axis in small increments.
