An upgrade from the K-Max, the 1zpresso K-Ultra features finer settings, better ergonomics, and a foldable handle to help you save space whether at home or when travelling. Equipped with the 1zpresso K burr, the K-Ultra is a fast and capable hand grinder for all brewing methods. Plus, it comes with a travelling case, making it practically ready to go with you anywhere!

Finer settings

The K-Ultra offers 100 clicks per rotation with an adjustment of 20 microns per click. Its easy-to-read dial features numbers from 1-10 to make it easy to remember where you’re at. When you open the grinder, the underside of the dial also features a white marker to help place your settings.

Compared with the K-Max which has only 90 clicks per rotation (22 microns/click), the K-Ultra lets you grind finer and helps you find the sweet spot for your coffee with better precision.

Better ergonomics

Several design improvements make the K-Ultra more of a joy to use. For starters, it is 20 grams lighter than the K-Max. Although that seems like a small difference, it is a significant improvement once the grinder is in use. It also has a slimmer profile which makes it easy to grip and its curved edges give it a more modern appeal.

Foldable handle

One of the highlights of the 1zpresso K-Ultra Hand Grinder is its foldable handle. The ergonomic handle has a curved form with an outer end that rotates downwards, reducing the total width of the unit. This is a great feature for a smaller kitchen where counter space is at a premium, and also great when travelling with your brew kit.


Made with stainless steel, the K burr was designed to handle a wide range of grind settings -- from filter to espresso. It has a heptagonal design which at 48mm cuts with efficiency and precision.
