Milling a hex on round stock in a vise
Jun 21, 2015· If you are just milling short hexes like bolt heads, one of those hex 5c collet blocks is made for that task, so long as the work will fit in a 5c. Can also use a 60 ° double angle cutter if the long part has to be held in the vise jaws. Set round on parallels, leave enough sticking up, and mill from both sides to make one corner.
