The Open Box Stile SD Espresso Grinder refines on the basics you need for excellent espresso. An on-demand only grinder, the Open Box Stile SD forgoes a timer and screen to offer solely portafilter-actuated grinding. Inside, you'll find the same stellar 58mm steel burrset found in the Stile, alongside a collar-style adjustment with unique micro-steps to make dialing in easier. Rancilio completes the package with a well-insulated case and low-static grinds path for hassle-free operation.
