The TIMEMORE Chestnut C3 is a manual coffee grinder built for consistent grinding across pour over, espresso, French press, and other manual brewing methods. It uses 38mm S2C660 stainless steel conical burrs, a dual-bearing shaft, and a 25g capacity to deliver even grounds in a compact travel-friendly size. Compared to basic hand grinders with plastic internals, the C3 uses an all-metal aluminum alloy body for better durability and stable grinding. S2C660 patented conical burrs made with 5-axis CNC machining and rated 55-58HRC for cleaner cutting and fewer fines About 36 grind settings with 0.0233mm adjustment per click for fine tuning from espresso to French press Double-bearing central axis helps improve alignment for smoother grinding and more uniform particle size Aluminum alloy body with no plastic internal parts for strength, heat control, and daily use Compact 52mm diameter, 138mm height, and about 530g for home, office, travel, hiking, or camping coffee setups Tool-free disassembly with included brush for quick cleaning between fresh ground coffee sessions This model is a practical upgrade from the C2, especially if you want better burr geometry and more clarity in the cup. The textured body improves grip while grinding lighter or denser specialty coffee beans. For one or two cups at a time, it fits neatly into portable coffee gear kits and works well with a moka pot, ceramic coffee dripper, pour over dripper, or travel brewing setup.
