Data from official source
The J-Ultra is the manual grinder 1Zpresso places at the top of its J series, the line built around espresso. The manufacturer states a 48 mm burr with "8-micron adjustments for fine to ultra-fine grinds", described with an advanced coating but without specifying its geometry (conical or flat) or the exact alloy: two figures left out of this listing because they are not stated.
The stated container capacity is 35-40 grams of ground coffee, while the total weight given by the manufacturer is 700 grams. Adjustment runs through an external stepped ring, consistent with the fixed 8-micron increment per click stated on the product page.
Compared with the rest of 1Zpresso's manual grinder range, the J-Ultra is marketed specifically for espresso: the manufacturer does not, however, give a stated grind range for other brew methods on this page.
