Our Verdict
The 1Zpresso K-Max is a premium all-rounder that bridges the gap between filter-focused grinders like the Comandante C40 and espresso-capable models like the JX-Pro. Its 90-click resolution gives you more than enough precision for any brew method, and the 48mm burrs keep grind times fast.
Pros
- + 90 clicks per rotation provide exceptionally fine grind adjustment for dialing in
- + Large 48mm burrs grind fast with excellent uniformity across all settings
- + Foldable handle and external adjustment dial make it convenient for travel and storage
Cons
- – Stepped adjustment means you cannot land between clicks for ultra-precise espresso tuning
- – Heavier than compact travel grinders at 700g, making it less pocket-friendly
Our Take
The 1Zpresso K-Max sits at the top of 1Zpresso’s versatile K-series lineup, designed as an all-purpose hand grinder that handles everything from espresso to French press. Its 48mm stainless steel conical burrs deliver fast grind times and excellent particle uniformity, rivaling electric grinders that cost significantly more.
What sets the K-Max apart from competitors like the Comandante C40 is its 90-click-per-rotation adjustment system. This stepped mechanism offers far more granularity than the Comandante’s 33 steps, making it easier to dial in for different brew methods without feeling like you are stuck between settings. The external adjustment dial is intuitive and holds its position well during transport.
The foldable handle is a nice touch for storage and travel, though the 700g weight means this is not the lightest option for backpacking. For home use and occasional travel, the K-Max is one of the best premium hand grinders available, especially for brewers who want one grinder to do it all without spending Comandante money.

Frequently Asked Questions
Is the 1Zpresso K-Max good for espresso?
The K-Max can grind fine enough for espresso with good consistency, but its stepped adjustment with 90 clicks per rotation means you may occasionally land between ideal settings. Dedicated espresso grinders with stepless adjustment offer more precision.
How does the 1Zpresso K-Max compare to the Comandante C40?
The K-Max has larger 48mm burrs for faster grinding and nearly triple the adjustment clicks per rotation, while the Comandante is lighter, has a more refined filter grind profile, and carries a stronger heritage brand reputation. The K-Max costs less and is more versatile.
What is the difference between the 1Zpresso K-Max and K-Plus?
The K-Max and K-Plus share the same 48mm burr set and body design, but the K-Max uses a slightly different burr coating optimized for a broader range of brew methods, while the K-Plus leans more toward filter brewing with its burr geometry.
