The round steel is turned into a flat point to simplify the cut. Insert the round die into the round die holder and take care that the groove of the round die is fixed with the middle screw of the round die holder. Fix all screws with attached screw driver so that the round die won’t slide. You can use the round die from both sides. It has a cut on both sides.
Pay attention to apply the round die even and use cutting oil. Now turn the round die under low pressure on the bolt. Rotate the round die back from time to time to break the chip.
