The Timemore C3s is a brilliant addition to Timemore's range of hand-held coffee grinders. Featuring an improved Spike-to-Cut (S2C) 660 grinding wheel set, based on the Chestnut X's popular S2C 860 burrs, the Chestnut C3s offers improved cutting performance, ensuring your coffee beans taste better with a consistent, fast grind, preserving the flavor of your coffee beans. The Timemore C3s hand grinder has also been upgraded to an all-metal aluminum alloy body, with no plastic parts inside, designed for precise grinding and durability. Fixed with a double-bearing design, the C3s makes the grinding process more detailed and the coffee grounds more uniform. With a diameter of 52 mm (2.05 inches) and a weight of 530 g (18.7 oz), the Chestnut C3s is easy to hold and carry, and has a generous capacity of 20 g (0.7 oz), enough for a cup or two of coffee. The C3s uses a reliable spring mechanism to lock the inner cutter in position and ball bearings to hold the grind shaft in place, to ensure you don't lose even a little grind quality. The well-designed handle connection gives this grinder exceptionally precise grinding and a smooth rotating handle with every rotation. Finally, the new and improved grounds container is made of aluminum for greater durability and a static-free grinding experience.
