The Original CNC Toolheads for Dillon 650 Press
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!
These toolheads are made to the highest standards by Whidden Gunworks. All critical machining is done on one operation, yielding tolerances of 0.0002" on all critical dimensions. This means that all die mounting holes are positioned precisely relative to each other and are exactly perpendicular to the flange. The flange is also flatter than possible with a cast toolhead. The 7/8"-14 die mounting threads are machined to Class 2B tolerance to better mate with the threads on your dies. This results in the dies being more accurately centered in each hole and reduces offset when tightening the die locknut.
The toolheads are machined from 6061-T6 aluminum alloy. The T6 tempering process yields an ultimate tensile strength of at least 42,000 psi. The result is a toolhead that is about 50% lighter than a cast toolhead, but also much stronger. These toolheads are thinner but have no voids or cavities on the bottom.
These toolheads come with the UniqueTek Toolhead Clamp Kit™ parts pre-installed. The Clamped toolheads mount with Grade 8 alloy screws (that come with the toolhead) instead of the Locator Pins. The major benefit of clamping the toolhead is a significant reduction in Cartridge Overall Length (COL) variation.
