The Lee Cutter with Ball Grip (No Lock Stud) works with all caliber sizes, so you do not need to waste money buying multiple tools or adapters. This cutter was designed to quickly and easily trim your cartridge cases after they have been stretched from being loaded multiple times. Not only is the Lee Cutter with Ball Grip versatile enough for use with multiple calibers, but it can also be turned either by hand or used with an electric drill. This handy tool eliminates the danger of long cases and also squares the case mouth for more accurate seating and exiting of the bullet.
