ARMANOV Short Trim Die Zero-Play Toolhead for Dillon XL 650 / 750 for RT-1500 Case Trimmer

The Zero Play toolhead does not use the original toolhead pins supplied by Dillon. It is bolted with two M3 bolts that lift the toolhead into the uppermost position.  When you cycle cases downward, the toolhead does not move, and cases go out in a straight line. Best practice is to loosen M3 bolts slightly before inserting the index shell-plate with case into dies and tightening M3 bolts to the toolhead's best position.
This toolhead is required for use with RT1500 Electric Case Trimmer. 
This combination is commonly used to trim 300 AAC Blackout on the XL650 & XL750
