Suitable Environment

Suitable Environment

The innovative Bunn G9WD-RH Weight Driven Grinder is truly a one-of-a-kind. Instead of using a timer to determine the grind volume, this unit utilizes weight-based portion control to accurate achieve the desired amount of coffee. Base on its impressive 6 pound capacity and precision, this grinder is recommended for high-volume commercial use.


Requiring very little training, the G9WD-RH has an extremely straightforward interface. Simply fill the hopper and program the amount of coffee you’d like to grind, by selecting the appropriate weight, and the grinder will do the rest.

Feature Details

Programmable Options

The Bunn G9WD-RH allows users to preprogram three different batch sizes for push-button delivery. Just choose the volume (weight) you would like to grind and program the machine; it will remember your setting for future use. Grinder controls are all accessible from the front for easy day-to-day operation.

Smart Funnel

A state-of-the-art microchip is embedded into the funnel, allowing it to recognize the grinder settings and recall them once attached to a BrewWise brewer. Information such as the type of coffee and batch volume allows the brewer to automatically select the appropriate brew cycle for your grinds.

Durable Burrs

The G9WD-RH’s metal burrs are rated at a Rockwell hardness of 66C, ensuring exceptional durability and performance. These precision burrs are designed to cut, not crush, coffee beans for consistent grind fineness and distribution.

Front Loading Hopper

The front-loading hopper has a six-pound capacity, allowing for easy operation and making it appropriate for use in busy establishments.


Daily Maintenance

Use a mild detergent on a clean, non-abrasive cloth to wipe away residue from the exterior of the machine. If possible, use stainless steel cleaner on all stainless steel surfaces.

Periodic Maintenance

About once a month, it is recommended that you clean the grinding burrs with Urnex Grindz. These food-safe tablets can be ground just like coffee beans to absorb coffee oils and loosen buildup inside of the grinding chamber.
