About the Timemore C3 Pro

The Timemore C3 Pro is a manual hand grinder with 38 mm conical burrs and stepped adjustment. At its coarsest it reaches about 1080 µm, so Percolator, French Press, and Cold Brew sit partly beyond its range. Each click moves the grind by roughly 30 µm.

What we found on this machine

Checked against

Timemore's Chestnut C3 Pro / C3 Max Pro manual, "How to Adjust". Read September 03, 2026.

The most useful thing on this document is its title page. It covers the C3 Pro and the C3 Max Pro, and it does not cover the plain Chestnut C3 — a trap this catalog had already been warned about once, and the reason the C3's page still carries no maker-backed number while this one does.

The settings are already in clicks, counted from the start point the same page defines. Timemore also prints a warning worth repeating: "To protect the burr, please DO NOT grind coffee beans at the finest 0-6 clicks." That is where this page's usable range begins.

Methods the Timemore C3 Pro covers

3 of these 19 settings are Timemore's own published figures. The rest are worked out from this grinder's range. Start there and adjust to taste.

The Timemore C3 Pro is a manual hand grinder with 38 mm conical burrs.

How much does each click change the grind on the Timemore C3 Pro?

Each click on the Timemore C3 Pro changes the grind by about 30 microns, so you can dial in small steps.

What grind sizes can the Timemore C3 Pro produce?

At its coarsest the Timemore C3 Pro reaches about 1080 µm, covering 19 of the brew methods we chart. Its finest setting isn't published, so we don't state one.

Can I copy grind settings from another grinder to the Timemore C3 Pro?

Not directly — every grinder's scale is arbitrary, so a number that works on one model won't match the Timemore C3 Pro. Match the micron range instead, using the chart above.
