1Zpresso X-Ultra vs KINGrinder K6
Two hand grinders cross-shopped at the same money. Both count 240 clicks — and the same number is not the same grind.
| X-Ultra | K6 | |
|---|---|---|
| Brand | 1Zpresso | KINGrinder |
| Scale | Clicks | Clicks |
| Dial range | 0 clicks – 240 clicks | 0 clicks – 240 clicks |
| Burrs | Conical | Conical |
| Espresso → filter | 73 clicks | 50 clicks |
| Filter → coarse | 131 clicks | 80 clicks |
The same number means different things
Both grinders use a clicks, which makes it tempting to copy a number straight across. Setting 120 clicks sits at grind index 47.2 on the X-Ultra but 71.5 on the K6 — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.
1Zpresso X-Ultra
KINGrinder K6
Dialing in the X-Ultra
The X series is 1Zpresso's more affordable line, and the X-Ultra is its all-rounder — positioned between the espresso-focused J-Ultra and the filter-leaning K-Ultra, and happy at either end without being optimised for one. The external dial gives 60 clicks a rotation across four rotations, so 240 settings at 12.5 microns each: the same step size as the JX-Pro and half that of the Q2, which is why espresso is genuinely dialable here. Seventy-three clicks separate espresso from filter, so small moves really are small. The one practical annoyance is that nothing tells you which rotation you are on — lose count and you return to zero and start again, though the dial lifts off to recalibrate.
Dialing in the K6
KINGrinder's all-rounder, and the value benchmark hand grinders get measured against. External adjustment, 60 clicks a rotation, at 16 microns a click — a coarser step than the 1Zpresso J and X series manage, and the one place you feel the price: espresso is dialable, but in slightly bigger jumps than a stepless grinder gives you. The 48mm stainless heptagonal burrs are what separate it from the rest of the KINGrinder line. If you only ever pull shots, the K4 is the espresso-specific sibling with titanium-coated burrs; the K6 is the one that covers pour over through espresso without being built for either.
