Our espresso only grinders are strictly dedicated for commercial espresso and cappuccino machines. There are many choices, and the prices are usually relative to the motor and grinding burr sizes. As your grinding demand increases, a larger motor and larger burrs are desirable to make certain there is less heat retention which can destroy the quality of your grinds.
Our commercial espresso only grinders usually have superior structural integrity than an all purpose grinder. They are however, typically limited due to the doser section (which limits clearance for ground coffee exiting) or the adjustment for grind fineness, which does not have the 'easy' ability to go from one extreme grind setting to another.
