Comandante C40 MK4: Specifications
| Specification | Detail |
|---|---|
| Burr size | 40mm conical |
| Burr material | High-nitrogen stainless steel (Nitro Blade) |
| Jar capacity | ~40g each |
| Included jars | Brown glass × 1, clear polymer × 1 |
Nitro Blade and Brewing Methods
Comandante describes the burr material as high-nitrogen stainless steel. This does not establish a surface nitriding treatment. The manufacturer covers coarse brewing through espresso and cezve/ibrik. Adjust clicks for your beans and brewing method.
No comparative particle measurements or taste tests are reported here. Consider materials, adjustment, and spare parts when judging the price difference.
Build Quality: A Grinder You Keep for Life
The C40's physical quality is immediately apparent on first handling. It feels substantial — more like a precision instrument than a consumer product.
The aluminum body is CNC-machined with tight tolerances. The included glass jar (brown, UV-resistant) produces less static than typical plastic jars, meaning ground coffee slides out cleanly. The clear polymer jar is provided for situations where you want to see the grounds.
The click-based grind adjustment system operates with a positive, tactile click at each step.
MK4 vs. MK3: The Improvements
| Feature | MK3 | MK4 |
|---|---|---|
| Burr precision | High | Higher (improved clearance tolerances) |
| Included jars | 1 | 2 (brown glass + clear polymer) |
| Handle ergonomics | Original | Ergonomically refined |
| Overall grind quality | Excellent | Marginally improved at fine settings |
The MK4's primary improvement over the MK3 is tighter manufacturing tolerances in the burr assembly, which improves consistency at finer grind settings. If buying new, always choose the MK4.
The C40's Limitations — Honestly Assessed
1. Espresso adjustment
The manufacturer provides espresso settings. Check the standard click increments and RED CLIX option if fine dialing is a priority.
2. Manual — no getting around the labor
Manual grinding time varies with beans and settings. Consider whether the effort fits your morning routine.
3. The price barrier
At ~¥48,000, the C40 costs four times a TIMEMORE C3S. Whether that four-times investment produces four times the enjoyment is entirely personal. For many specialty coffee enthusiasts, the answer is yes — but it requires genuine coffee engagement to justify.
Pros
- +Nitro Blade burr delivers near-commercial grind uniformity
- +Engineering and build quality built to last decades
- +Click adjustment system enables repeatable fine-tuning
- +Exceptional pour-over, AeroPress, and cold brew performance
Cons
- -~¥48,000 — four times the cost of the TIMEMORE C3S

Who Should Buy the C40
Buy the C40 if you:
- Brew pour-over or AeroPress with single-origin specialty beans regularly
- Have exhausted what your current grinder can achieve
- Want to own a grinder once and not upgrade for 10+ years
- Care about the ownership experience alongside performance
Don't buy the C40 if you:
- Are new to specialty coffee
- Need continuously variable espresso adjustment
- Have a budget under ¥30,000
- Plan to transition to an electric grinder in the near future
Final Verdict
The C40 combines Nitro Blade burrs with click adjustment. The manufacturer covers a broad range of brewing methods. Consider manual effort, adjustment increments, and spare parts alongside the price.
