The short answer
Choose the Timemore C3 for a compact, light first hand grinder for filter coffee. Choose a 1Zpresso for espresso: the K-Ultra if you switch methods daily, the JX-Pro if you brew espresso first. The 1Zpresso grinders use larger 48 mm burrs, and the JX-Pro the finest steps per click.

1. Choose this for a compact first hand grinder
Timemore Chestnut C3
Manual tier · The budget hand grinder that made stainless conical burrs cheap.
38 mm S2C steel burrs in a light aluminum body.
The Chestnut C3 uses S2C steel burrs in a 38 mm size, taken from Timemore's more expensive Chestnut X, in an aluminum alloy body with a textured grip.
Timemore describes it as suited to everything from espresso to pour-over and French press, with roughly 36 settings at about 23 microns per click.
It is light and compact, which makes it an easy travel grinder.
Its smaller burrs are the trade: at 38 mm against 48 mm, it has less cutting surface than the 1Zpresso grinders here.
Specification
- Burrs
- 38 mm S2C stainless conical, 55-58 HRC
- Settings
- Roughly 36, about 0.0233 mm per click
- Capacity
- 25 g
- Weight
- About 530 g
- Build
- Aluminum body, double-bearing axis, no plastic internals
What it does well
- Filter-grade grind quality at a genuinely low price
- Metal internals and double bearings, not a toy
- Small and light enough to travel with
Where it gives ground
- 38 mm burrs make an espresso dose slow work
- Espresso resolution is marginal
- 25 g capacity limits you to one brew at a time
Skip it if
Skip it if espresso is your main drink. A 48 mm grinder with published fine steps suits espresso dialing better.
2. Choose this for espresso and filter
1Zpresso K-Ultra
Manual tier · A 48 mm hand grinder with external adjustment, built as an all-rounder.
48 mm heptagonal burrs and an external 100-click ring.
The K-Ultra uses a 48 mm heptagonal conical stainless burr with an external ring at 100 clicks per rotation, listed at 20 microns per click. It weighs 685 g.
One full turn moves the burrs about 2,000 microns, so moving between espresso and filter settings is quick.
Its magnetic catch cup holds 35 to 40 g.
Specification
- Burrs
- 48 mm heptagonal conical stainless (K burr)
- Adjustment
- External ring, 100 clicks per rotation
- Resolution
- 20 microns per click
- Weight
- 685 g
- Catch cup
- Magnetic, 35-40 g
What it does well
- External adjustment - you change grind without opening anything
- Seven cutting edges rather than six speeds the grind up noticeably
- Genuinely good across espresso, filter and French press
Where it gives ground
- 20 microns per click is coarser than the JX-Pro espresso resolution
- Heavier than a travel grinder should be
- Premium price for a hand grinder
Skip it if
Skip it if you only brew filter and want the lightest grinder to carry. The C3 is smaller.
3. Choose this for espresso steps
1Zpresso JX-Pro
Manual tier · A 48 mm hand grinder with internal adjustment fine enough for espresso.
48 mm burrs at 12.5 microns per click.
The JX-Pro uses a 48 mm steel conical burr with internal adjustment at 40 clicks per rotation, listed at 12.5 microns per click - the finest published step here.
Fine steps are what espresso dialing needs.
Internal adjustment makes switching methods slower than an external ring.
For espresso-only brewers, that is a small price for the resolution.
Specification
- Burrs
- 48 mm steel conical
- Adjustment
- Internal, 40 clicks per rotation
- Resolution
- 12.5 microns per click
What it does well
- 12.5 microns per click is finer resolution than most electric grinders
- 48 mm burrs make short work of an espresso dose
- No power, no static, nothing to break
Where it gives ground
- The adjustment dial sits inside the hopper - you lift the lid to change it
- Grinding espresso by hand every morning gets old for some people
- No dosing aid: you weigh in, you weigh out
Skip it if
Skip it if you switch methods every day. The K-Ultra's external ring is quicker.
Burr size and what it means
Larger burrs have more cutting surface, which is one reason the 48 mm grinders are favored for espresso. The C3's 38 mm burrs are well suited to filter brewing and keep the grinder small and light.
Microns per click make adjustment easy to reason about - about 23 on the C3, 20 on the K-Ultra and 12.5 on the JX-Pro - see 1Zpresso vs KINGrinder K6 for another 48 mm comparison.
