83mm Mazzer Conical Burrs and Integrated Bean Feeder

These 83mm conical burrs are the largest for home/commercial grinders, ensuring exceptional grind quality across brew methods. 5,000Kg rating for outlasting several lifetimes of heavy use. Pre-aligned, pre-seasoned for great flavor extraction. TiN coating enhances longevity while food-safe. Integrated bean feeder maintains consistent grind quality.

Transmission Gearbox

Transmission Gearbox

A first in a manual grinder, we designed and manufactured our own 2-speed transmission. Lighter roasts are no longer a burden to manually grind. Drop down to 1st gear and let the gearbox cut your effort in half. For darker roasts jump up to 2nd gear for a faster grind.

Magnetic Dust Lid

Magnetic Dust Lid

We've brought the KEY's popular anti-popcorning and dust lid to the HG-2. Magnets allow the lid to pull apart and off for cleaning, or straight up and suspended with magnets for loading beans into the burr chamber. Once loaded, the cover easily drops right back down into place, preventing any fragments from bouncing out during grinding.

Magic Tumbler

Magic Tumbler

Our patented mechanism for automated WDT grounds homogenization. Zero overspill, ready to drop into your portafilter, aeropress, moka pot, or pour-over apparatus. Mk2 improves upon this with EG-1 inspired wipers that further reduce retention and static, all but eliminating the need for RDT.

Integrated Cleaning Brush

Integrated Cleaning Brush

Solid teak handle, solid brass ferrule to protect the bristles when they go back into the handle, and a hidden magnet to hold it in place. Unparalleled details that show your dedication to cleanliness. The brush head screws out and can be replaced individually.

Maintenance and Cleaning

The HG-2 has been designed from the start to be both simple and easy to clean. No tools, and a full clean in seconds, not hours.

The dust lid can be removed or suspended above with magnets to reveal the bean feeder aperture at the top of the burrs. A few brush strokes and blasts of air on top can dislodge any powder above the burrs. The lower funnel is held in place by 12 strong rare earth magnets and can be removed with a simple twist of the wrist. Once exposed, the lower burrs can be brushed clean in seconds.

We believe that a good product is a clean product, and designing them to be easy to clean is fundamental to improving the quality of your coffee and the hygiene of your countertop.

03

Burr Alignment

The HG-2 comes factory pre-aligned, and cleaning or normal use will not disrupt this. You should never need to touch this. At the factory, we make sure that each axis is aligned and centered to the best capability of the set of burrs being used. We then tighten it all down, grind an espresso shot for verification, and clean the burrs before boxing it up. This means you may see a tiny amount of coffee dust in the product, but it is not "used."

04

Burr Replacement

The HG-2's pre-seasoned 83mm Mazzer Conical Burrs are rated for over 5,000Kg of coffee, theoretically they should last you several lifetimes. Small pebbles in your bag can throw a wrench in their longevity, however.

If you do need to replace them, we stock our burrs that come with our proprietary partial pre-seasoning and life-prolonging food safe TiN coating. Find them here.
