hex 4mm. Center drill, drill, rotary broach, drill just for clean the hole. Enjoy.

Interesting. One thing though you really need to align your tailstock, as you can see when you drill or broach the tool pulls over to centre as you contact the workpiece.

Did you make a video of you making the broach itself? I would love to see that!
