Unlike the least expensive coffee grinders that use spinning blades to slice uncontrollably the coffee, our grinder features burr grinding rings for milling coffee beans to an adjustable, uniform size. The grind size is adjustable for a large range of settings from the finest powder for espresso to medium grinds for drip coffee makers to coarse grinds for urns and percolators. The grinder also features a Quantity Selector that allows you to grind 2 to 16 tablespoons of coffee with one-touch operation and pulse. Thanks to the unit's Dual Safe System feature, the grinder stops if either the ground coffee container or bean hopper is removed.
