Description
A Manual Coffee Grinder Built for the Single Cup
Most manual coffee grinder options trade consistency for portability. The Precision R3 refuses that compromise — a 20g chamber and weighted body engineered for one clean cup, whether at a home bar in Mumbai or a café counter in Bengaluru.
Built Around Precision
Every component of the R3 is chosen for stability and grind consistency. Food-grade steels and a walnut handle accent bring durability without adding bulk, while the weighted body keeps grinding motion steady from the first crank to the last.

Engineered Advantages
- Food-grade SUS304, SUS420, aluminium alloy, silicone, and walnut construction
- 725g weighted body for stable, controlled grinding
- Integrated grounds container with built-in sieve for uniform particles
- Four dedicated sifters to isolate ultra-fine particles
- Magnetic walnut handle for smooth, secure cranking
What Sets the R3 Apart
20g Chamber
Sized for single servings, so beans are ground fresh, brew by brew, without excess left oxidising in the hopper.
725g Weighted Body
A heavier frame keeps the grinder planted on the counter, reducing wobble and improving grind uniformity.
Premium Materials
SUS304 and SUS420 steel, aluminium alloy, silicone, and walnut combine for durability and a refined finish.
Built-In Sieve
The integrated grounds container sifts fines during grinding for more even extraction and less mess.
Four Dedicated Sifters
Separate ultra-fine particles with precision, protecting flavour clarity in every brew.
Travel-Ready Design
Compact and durable enough to move from a home kitchen to a weekend trip without losing performance.
