We've had plenty of requests for this little gizmo. This tool is threaded 8-32 on one end to accept case neck brushes and 1/4" drive on the other end to adapt to use in a power screwdriver.
Works well, It doesn't fit as tightly as I would like but that might be my Ryobi power drivers drive socket.
Well made quality item for reloading. It should last a lifetime. Another quality product from PMA.
