  • Enjoy the Grind

    Engineered for precision and performance, the ROK Grinder GC features hardened steel conical burrs, a long & stable axle, and a fine-pitch stepped adjustment to provide a consistent grind with great control—from ultra-fine to coarse.

    Enjoy gently milling your beans with ROK's more ergonomic vertical action and extra long crank arm, designed for utmost comfort and feel. With a simple hand-turn adjustment wheel, glass composite base, and bamboo composite grounds cup for reduced static charge and easier dosing, the ROK Grinder GC puts you in control of a truly hands-on experience and is the perfect complement to your rise and grind ritual.

  • Features

    Double bearing drive shaft and 48mm hardened steel conical burrs provide excellent stability and grind particle size consistency.

    Stepped & calibrated hand-turn adjustment wheel allows for complete range of precision grind size settings—from Turkish to Cold Brew; each click of the wheel represents a 58-micron adjustment.

    Manual control of grind speed allows prevention of heat build-up in the burrs (which can degrade the flavour of your coffee).

    Bamboo composite grounds cup allows for easier filling and dosing with reduced static charge; base of grounds cup doubles as a tamp for the ROK Espresso GC portafilter basket.

    Ergonomically designed with long handle, wide non-slip base and long-lasting acetal bevel gears for maximum comfort and efficiency.

    Precision die-cast aluminium body and glass composite (GC) base.
