This toolhead has lock rings that allow the sizer and seater dies to float. This floating action allows the dies to center themselves exactly over each cartridge for the best possible alignment and more concentric ammunition.
What is concentricity and what does it matter?
Concentricity refers to how straight the bullet is on top of the loaded round. A bullet that is straight will enter the rifling in the barrel that way. Bullets that enter the rifling slightly crooked do not shoot with their highest accuracy.
What's wrong with using the OEM toolheads?
The Dillon presses are great machines made to high quality standards. However, the cast toolheads have limitations. How do we know if the toolhead flange is flat? How do we know that each threaded station in the toolhead is in perfect alignment with the shellplate? How do we know that the stations are equally spaced? All of these areas compound for possible misalignments and lead to ammunition that isn't quite as concentric as it could be. The toolhead is the final link between your dies and your press so it only makes sense that quality is extremely important. With over $100.00 of dies, powder measure, and other accessories mounted in your toolhead, don't you want to know it's the best available!
What is different about the new CNC Machined Toolhead?
These toolheads are made to the highest standards. The are CNC machined from 6061-T6 aluminum, which is much stronger and has less flex than a cast toolhead. All critical dimensions are machined in a single operation, ensuring that all surfaces are true and aligned relative to each-other. The die holes are positioned with a very high degree of accuracy and the 7/8-14 threads are machined to a Class 2 fit, yielding dies that are more precisely centered in each hole and better aligned to the cartridge cases in the shellplate. The flange is also flatter than can be achieved with a cast toolhead.
Will this system really load ammo good enough for 1000 yard shooting?
"Absolutely. I have been loading all of my competitive ammo, for practice and matches, on a 650 with a floating die toolhead since 2003. The ammo that I will be taking to the World Palma Team Championships and World Long Range Individual Championships will be loaded on this machine. You have my personal guarantee that this will load the best ammo your dies can produce. If you're not 100% satisfied, send it back for a full refund."

What is the UniqueTek Toolhead Clamp Kit™ and how will it help?
These toolheads come with the UniqueTek Toolhead Clamp Kit™ parts pre-installed. The "clamped" toolheads mount with Grade 8 alloy screws (provided with the toolhead) instead of the original locator pins. With the toolhead clamped, you will achieve reduced cartridge OAL variation. The floating dies will also work more effectively without the added, and unpredictable, movement of the toolhead during each press cycle. You can read more details about the benefits of clamped toolheads on the product page for the UniqueTek Toolhead Clamp Kit™.
— 550 Floating Die Toolhead = $74.95
— 650 Floating Die Toolhead = $79.95
* Each Floating Die Toolhead comes with 2 special die lock rings and with the UniqueTek Toolhead Clamp Kit™ parts preinstalled.

Q: I'm loading only pistol ammunition. Will the floating dies help me?
A: No. Since typical pistol bullets are not pointed and are fired at relatively short range, runout is not a significant factor in accuracy. The full benefit of floating dies will be realized only when loading spire point bullets, where runout can significantly effect accuracy ... especially at long rages. For loading pistol cartridges, and rifle cartridges for short range and "plinking" we recommend using our CNC Machined Toolheads without the floating die feature.
