Data from official source
The K-Ultra is the flagship of 1Zpresso's K series, positioned as an all-round grinder rather than one dedicated to espresso alone. The manufacturer states a "heptagonal conical" burr, described as built to suit multiple brew methods, but does not give its diameter in millimetres or its exact material on any of the official pages reviewed.
Adjustment is stated across 100 clicks per rotation (10 numbers, 10 clicks each), with a 20-micron increment per click: a system of fixed positions, not continuous. Container capacity is given as 35-40 grams, total weight as 700 grams.
Compared with the espresso-focused J-Ultra, the K-Ultra is presented by the manufacturer as the more versatile choice in the upper range, covering more brew methods with the same burr.
