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 5.2 on the J-Max 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.

Dialing in the J-Max
The J-Max trades coarse range for espresso resolution, and the click density near the fine end is the whole point of the grinder. If you are using it for pour over you are working in the middle of its range and will find it forgiving; if you are pulling shots, expect meaningful taste changes from two or three clicks. It will reach French press, but it is not what you bought it for.
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.
