Timemore Chestnut C3S Pro Hand Grinder

The Timemore Chestnut C3s PRO is a standout among premium hand grinders, offering impressive performance in a sleek, portable design. Its stepless grind adjustment makes it simple to fine-tune your grind size for any brew method—from espresso to pourover to French press—giving you total control over your coffee experience.

Designed for performance and convenience, the C3s PRO features a space-saving folding handle and the upgraded Spike-to-Cut (S2C) 660 burr set, inspired by the acclaimed S2C 860 found in the Chestnut X. With a hardness rating of HRC 55–58, this burr system delivers fast, consistent, and precise grinding that helps retain the full flavor of your beans.

Crafted with an all-metal aluminum alloy body and no plastic internal components, the C3s PRO is engineered for durability and consistent performance. Its dual-bearing stability ensures uniform grounds with every crank.

Compact yet capable, the C3s PRO measures 51mm (2.01”) in diameter, weighs just 473g (16.7oz), and holds up to 20g (0.7oz) of coffee—perfect for one or two fresh brews on the go.

Additional design upgrades include a reliable spring-loaded burr locking mechanism, ball bearings to stabilize the grind shaft, and a newly improved aluminum grounds bin for reduced static and increased durability. Each turn of the handle is smooth and efficient, making grinding feel effortless and precise.
