The Dormer M Gun nosed die is a solid die for external thread. It is generally for use on lathes, small diameters can be produced by hand with a die stock holder. The gun nose will drive the chip ahead of the cutting edge, increasing performance. The bright finish lapped surface prevents the work piece material from sticking and improves the threading action.
