The K+M large calibre neck turner body has a very unique cutter adjustment mechanism that allows for a very precise cutter adjustment. This design incorporates very fine pitched threads of a screw within a screw concept which yields 0.002” cutter advance for each rotation of the adjustment nut.

As a point of reference and comparison, a micrometer advances the spindle 0.025” for every revolution of the thimble. There are etched markers on the neck turner body around the circumference of the cutter adjustment screw hole placed every 30 degrees radially and as a reference, there is one punch mark on the face of the adjustment nut. When the adjustment nut is rotated one increment the cutter advancement is 0.0002”.
