This is the automatic sizing head that engages with the automatic sizing tool. It uses a square drive to interface with the tool and it features a subtle helical design. You can think of it almost like a very fine thread. With the help of your drill, these sizing heads essentially screw themselves into the bushings. Since that completely eliminates the physical pushing necessary with manual sizing tools, it means that you can insert even large sizing heads into bushings with very little effort.
Look how quickly a sizing head gets through a bushing on my Youtube.
