Say hello to the perfect grind.

The 1Zpresso K-Max is the ultimate tool for every coffee connoisseur’s kitchen, designed to deliver flawless results every time. Featuring an ultra-precise external adjustment ring, this grinder offers complete accuracy when creating exceptional espresso and pour-over coffee.

The K-Max combines the excellence of its cousins, the K-Pro and K-Plus, with a slimmer magnetic catch cup for the grind collection. Grinding coffee will never be a chore again thanks to the K Burr feature, created with the large 48mm specialized stainless steel for consistent performance. Since the K Series is designed for excellence, you can clean easily without professional tools. Enjoy a bright, clean-tasting brew with every fresh grind.


With 9 numbers and 90 clicks on the dial, each click shifting the grind by 22 microns. This allows you to use a fine grind when brewing with an espresso machine and to find the "sweet spot" when dialing in your espresso.
Higher numbers signify a coarser grind. The design allows for a quick adjustment to your preferred grind setting.
