PRODUCT DESCRIPTION The TIMEMORE Chestnut C3S Manual Coffee Grinder is a premium, all-metal manual coffee grinder that bridges the gap between portability and professional-grade performance. It is specifically engineered to eliminate plastic components, offering a more durable and stable grinding experience than its predecessor, the C3. Precision Engineering & Performance PATENTED S2C660 "SPIKE TO CUT" BURRS: Features 38mm CNC stainless steel conical burrs that pre-cut beans into smaller fragments before grinding. This design reduces fines and produces a cleaner, more complex flavor profile with higher clarity. ALL-METAL INTERNAL SUPPORT: Unlike earlier models that used plastic frames, the C3S features an aluminum alloy unibody and internal supports for the central axis. This enhances structural integrity and ensures the burrs stay perfectly aligned during use. DUAL-BEARING SYSTEM: The central shaft is held by two precision ball bearings, providing a smooth, effortless rotation and highly uniform grind size. Versatility & Portability UNIVERSAL BREW RANGE: In terms of precision adjustment, the C3s features a dial plate with 12 clicks per rotation. It offers roughly 36 levels of point-to-point coarseness adjustment. The C3S is geared toward users who mostly make filter coffee, Moka pot, pour-over, Aeropress or French Press. The 12-click system is faster to navigate for coarse adjustments. TRAVEL-READY DESIGN: Weighing approximately 530g with a 52mm diameter body, it is sized for a comfortable grip even for those with smaller hands. ENHANCED STABILITY: The "S" in C3S denotes the new silicone base, which provides an anti-slip grip and a soft touch when placed on tabletops. BEAN CAPACITY: The re-engineered interior allows it to hold up to 25g of beans, which is roughly 25% more than the original C3, making it ideal for brewing 1–2 cups per session. PRODUCT DETAILS MATERIAL: Aerospace-grade aluminum alloy body with HRC58 hardened stainless steel burrs. DIMENSIONS: The body measures approximately 147mm x 52mm.
