Product Description

Made possible by a dedicated community of crowd funders from Indiegogo, the ROK Coffee Grinder is a revolutionary manual grinder for all forms of coffee preparation.

The grinder boasts durable die cast aluminum construction with engineering grade components for ergonomic operation and long lasting performance. Your coffee is ground by a set of 48mm hardened steel burrs with a double bearing drive shaft and a Acetal plastic gears. The grinder can also be adjusted between stepped and stepless grinding by fitting the adjustment wheel with a washer for infinite grind settings.

Unlike most manual grinders, beans are evenly ground with minimal effort. The non-slip ring located below the base ensures complete stability while the grinder takes only 62 revolutions (approximately 30 seconds) to prepare a double shot of espresso.

Each ROK Coffee Grinder also ships with a metal cup/tamper that can be used to measure whole beans, catch ground coffee, and tamp the portafilter of the ROK Espresso Maker.

Great Grounds, no Workout

The ROK Grinder requires less than half the revolutions of a standard manual grinder, clocking only 62 revolutions (roughly 30 seconds of grind time) to grind a double espresso. This speed is comparable to a quality electric grinder while significantly quieter (75 decibels).

Stepped / Stepless Grinding

With the ROK Coffee Grinder it's your choice whether you prefer stepped or stepless grinding. A pair of washers can be installed or removed from the double bearing drive shaft to transition the grinder from stepped or stepless grinding. Stepless grinders have an infinite number of grind settings allowing you to dial in your exact fineness for the perfect extraction parameters.

Engineering Grade Acetal Gears

The gears that power the ROK Coffee Grinder are made from Acetal, an engineering plastic that possesses qualities of both plastic and metal. With high tensile strength, low friction, light weight, and durability, it was the perfect choice for a reliable, long lasting set of burrs.

Left Handed Conversion Instructions

Are you a lefty? If so, each ROK Coffee Grinder ships with a set of instructions to quickly switch the base around and refit the grinder for use with your left hand.

48mm Hardened Steel Conical Burrs

Your coffee is ground fresh every time with a set of 48mm hardened steel conical burrs that were hand picked by the engineers at ROK for use with this grinder.

Non-slip Base

The non-slip ring located underneath the base guarantees stability while grinding on any flat surface. Secure it to your counter or tabletop for a semi-permanent fixture in your kitchen.
