Balanced extraction flavors start with the right amount of grinds. So how do you ensure a consistent grind every time? Conical burrs ensure a more even grind while the adjustable Razor™ dosing tool helps to trim the coffee puck before each extraction for an even dose of coffee grinds every time. Fully adjustable, the Razor is suitable for 58 mm, 54 mm and 50 mm portafilter baskets. Grind directly into the portafilter using the hands-free grinding cradle and cleaning is made quick and easy with a removable grinds tray. Portafilter not included, sold separately See less
