Comandante C40 MK4 vs Kinu M47 Phoenix
The two hand grinders people step up to, and their dials disagree.
| C40 MK4 | M47 Phoenix | |
|---|---|---|
| Brand | Comandante | Kinu |
| Scale | Clicks | Clicks |
| Dial range | 0 clicks – 50 clicks | 0 clicks – 100 clicks |
| Burrs | Conical | Conical |
| Espresso → filter | 18 clicks | 35 clicks |
| Filter → coarse | 14 clicks | 40 clicks |
The same number means different things
Both grinders use a clicks, which makes it tempting to copy a number straight across. Setting 25 clicks sits at grind index 37.3 on the C40 MK4 but 18.4 on the M47 Phoenix — far enough apart to change the cup.
Converting a setting

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 C40 MK4
The reference hand grinder for filter, and its click scale has become a de facto standard — plenty of published recipes quote "C40 clicks" as though it were a universal unit. It is not, which is the reason this site exists. The MK4 runs coarser than most people assume relative to electric grinders: if you are converting a recipe written for a Baratza, do not simply match the number.
Dialing in the M47 Phoenix
The Phoenix is the more affordable M47 with the same burr set and grind character in a simpler body. Dial behaviour matches the Classic closely enough that notes transfer between them.
