Includes press adapter and one mandrel.

Virgin/competition Brass isn't quite ready to Neck Turn when you buy it. And the commercial die manufacturers have no set standards for the Expander button in their dies.
Large variations from manufacturing to manufacturing and even within a given manufacturing makes it necessary to properly size the inside diameter before turning.
Don't be fooled by slick talk. The turning pilot cannot be used to correctly expand the case neck because of the elasticity of the brass; it will spring" back and be too tight for proper Neck Turning.
The 7/8-14 Threaded Adapter fits your Normal Reloading press and the interchangeable Mandrels are sized to be the perfect companion to the K & M MICROADJUSTABLE Neck Turner. The EXPAND MANDRELS will iron out (smooth) and slightly expand the case neck so the brass will spring back to the correct size needed to neck Turn your Pet Brass.

This tool can also be used to expand up to a larger caliber; great for the Wildcatters.
To remove the DREADED DOUGH-NUT, adjust the bottom screw to stop the NECK EXPANSION just short of the DOUGH-NUT. Then the neck is the correct size for the K & M FLUTED CARBIDE neck turner pilot to remove said Dough-Nut.

Mandrels are available in cal. .17, .19, .20, .22, 6mm, .25, 6.5mm, .270, 7mm, .30, and .338. Each Mandrel has an adjustment screw to bottom-out in the Brass before the case mouth can hit the mandrel's shoulder.
