With fixed center design, multi-port spiral flow design, and gum space adjustment, Bullet II eliminates need for fastening hardware. It takes 1/2 turn of cam lock to remove and install deflector and tip, while threaded retaining ring for die and threaded tip retainer accelerate tool changes. Tooling retainers also serve as means of gum space adjustment. While dies are removed from front, tips are removed from rear. Air/vacuum connection is designed to minimize required effort.
