UniqueTek Whidden CNC Machined Tool Head Dillon RL 550

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. They come with UniqueTek Clamp Kit installed.
