The conical milling head is made for precision (milling) technique, where a defined taper angle produces convergent surfaces on telescope and attachment work. The pre-shaping cut removes stock quickly in the first milling pass and is followed by the fine and super fine cutters. With a 2° taper it mills surfaces that are nearly parallel, for telescope crowns and attachments with minimal draw.
