83mm Conical Burr Hand Grinder
Regular price $1,750 USD $
Regular price USD Sale price $1,750 USD
Finish | Onyx Finished in Onyx


The HG-1 represented a true revolution in hand grinding, but we firmly believe every tool can be iterated on and improved. With the benefit of lessons learned ourselves and from our customers, we went back to the drawing board to completely redesign and re-engineer the HG-1. The result? The new gold standard of hand grinders: the HG-2. New orders ship immediately.

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 upper funnel can be lifted away to reveal the top of the burr set. A few strokes with the brush that's always ready to deploy from the handle removes any stray coffee grounds. 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.

Burr Alignment

The HG-2 comes factory pre-aligned, and cleaning or normal use will not disrupt this. If you do a full teardown and clean, you may want to re-align your grinder. The HG-2 is designed to be accurately aligned to an incredibly precise level in a matter of minutes.

For a simple but accurate alignment, just do the following:

  1. Adjust the grind setting to its coarsest level

  2. Using the 5mm hex key included with every HG-2, lightly loosen the two bolts below the Burr Mount. These bolts are visible when looking up at the bottom burr, near the main body. The outer burr and its holder should still be able to move along the flat surfaces when pushed, but should not be so loose they sag.

  3. While slowly cranking the grinder, slowly adjust the grind setting finer until burrs begin to rub.

  4. Continue adjusting finer until just before the burrs are no longer able to spin. At this point, the burrs have reached peak concentricity.

  5. Tighten the two bolts below the Burr Mount to lock the alignment in place.

  6. Loosen the grind setting to un-bind the burrs. You’ll need a full-turn away from the locked position to be in a usable range.

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.
