Description
A manual coffee grinder built for precision, not compromise
Uneven grounds ruin extraction before water ever touches the coffee. This manual coffee grinder solves that at the source, with a stable, weighted body and a sifting system that separates fines from your dose.
Built around consistency
Every component of the Precision R3 Pro is chosen for stability and repeatability. The 725g weighted body keeps the grinder planted during use, so grind speed and pressure stay consistent from the first bean to the last. A silver-finished body with a walnut handle accent brings warmth to a precision instrument, equally at home on a café counter or a kitchen shelf. The compact 20g chamber keeps grinding sessions focused on single servings, so beans are never sitting around losing aroma before brewing.
Engineered for clean extraction
- Food-grade SUS304 and SUS420 steel components resist wear and retain sharpness
- Integrated sifter separates fines from boulders during grinding
- 4 dedicated sifters allow particle-size fine-tuning for different brew methods
- Aluminium alloy and silicone parts reduce static and grind retention
- Weighted 725g body for stability during manual grinding
What sets the Precision R3 Pro apart
Precision Engineering
Tight tolerances across the grinding assembly deliver consistent particle size across pour-over, espresso, and immersion brewing.
Premium Materials
Food-grade SUS304, SUS420, aluminium alloy, silicone, and walnut combine durability with a refined, tactile finish.
20g Chamber
Sized for single servings, so beans are ground fresh for each cup rather than sitting in a bulk hopper losing aroma.
Built-In Sifting
An integrated grounds container with a built-in sieve filters fines as you grind, for cleaner, more even extraction.
Travel-Ready Build
Compact and durable enough for hotel rooms, offices, and weekend trips — no compromise on grind quality away from home.
Modern Aesthetics
A silver finish with a walnut handle accent gives this manual coffee grinder a refined look on any counter.

Frequently asked questions
What beans can I grind in the Precision R3 Pro?
Use it only for roasted coffee beans. It is not designed for spices, grains, or any other material.
How much coffee can I grind at once?
The chamber holds 20g, ideal for single-serve brewing methods like pour-over or AeroPress rather than batch brewing.
How do I clean this manual coffee grinder?
Empty and clean the powder container after every use. Use an air blaster and brush on precision parts, and avoid swapping sieves while grounds remain in the bin.
What are the 4 sifters for?
Each sifter separates a different particle-size range, letting you fine-tune grind consistency for different brew methods and reduce fines in your final cup.
Is it suitable for travel?
Yes. Its compact size, fully manual operation, and durable SUS304/SUS420 build make it a dependable travel companion for hotel rooms and offices.
