This toolhead is designed to be a direct bolton upgrade for your Dillon S1050 / RL1100. It uses a standard 7/8-14 UNF thread so all industry standard dies and locking rings can be used.

This toolhead features a modified 3mm thinner die base that allows you to mount dies with super short threaded portion with no problem. The thinner base also gives room for the new big feature of this toolhead. The Free Float system. You can now use our super popular Free Float Rings to mount your dies. This system allows each die to self-center on each case, without transfering small vibrations and movements to the other dies. The result? More consistent, concentric and precise ammo.

This Free Float system also allows super fine die depth adjustments and die change. Because the lock ring is locked onto your die, it also allows the die to sit in the exact same position every time you mount it on the same toolhead station.

This toolhead also offers an extra 7/8-14 UNF threaded die station (nr.4) over the timer seating mechanism. This allows you to add an additional die like a Hold Down die or a Flare & Expander die. 

The kit comes with all the pins preinstalled, and 2 different ratchets, depending on if you use the machine on the  S1050 or RL1100. We also include an upgraded Shellplate Lock Nut that uses a single brass tipped retaining screw instead of the original 4 fiddly top plastic pressure plates. This makes shellplate removal and proper shellplate tension setting supper easy and quick.
