The Kinu M47 Phoenix is a lightweight, high-end manual coffee grinder known for its precision, consistency, and travel-friendly design, using Black Fusion-coated 47mm burrs and a micrometric, stepless adjustment system that allows for 0.01mm increments in grind size.
Country of origin: Kinu is a family owned German company.
I understand the grinder is made in Romania.
About $260 AUD
It features a stainless steel body, ABS plastic components for hopper and catch-cup, and is designed for both espresso and filter brewing, offering a smooth, stable grinding experience ideal for home or on-the-go use. This is the lightweight version .. more plastic. But there are more expensive versions of the M47 with more robust casing (still identical internal burrs).
Versatility:
Suitable for various brewing methods, from espresso to French press, delivering consistent results for different coffee styles.
Smooth Operation:
Utilizes four fixed steel ball bearings to ensure a smooth, stable, and wobble-free grinding motion.
The build quality is excellent. relatively fast grinder
Features a stepless, micrometric grind setting that allows for precise adjustments in 0.01mm (10 microns) increments, providing excellent control over the grind size.

Grinder adjustments for Espresso:
Many grinders have a 30-micron increment that can be too coarse for dialing in espresso.
In general, the lower the the microns per click, the better your grinder will be for espresso.
By increasing the threads on the adjustment axle, we can increase the number of available adjustment settings thus making it easier to achieve the very precise grind sizes needed for espresso.
A good grinder adjustment for espresso is a step size that's between 5 and 15 microns per click to allow for precise dialing in the shot. Though some grinders are stepless, offering infinite adjustment. The best adjustment size depends on the specific grinder and the sensitivity of your espresso setup, as a single click can significantly affect your shot time and flavor.
Examples of Grinder Adjustments
Jmax: 8.8 microns per click
Comandante C40: 25-30 microns per click
Comandante C40 with Red Clix: 15 microns per click
Timemore C3: 83 microns per click

There are 2 Burr styles. Both 47 mm
Pour over
While the main parts are made in their factory, the burrs, a critical component, are I understand sourced from an Italian company
(Italmills ??).
Made from Black fusion steel.
Standard
I use this grinder mostly for espresso so have stuck with the standard burr.
On a setting of 1.0 it takes about 50secs.
I think this burr has really high clarity .... really sharp tasting... possibly fewer fines that I'd usually expect from a cone burr
There are quite a few very similar grinders using 47mm conicals from Italmills.
These might perform similarly. .... though I don't own any of these and can't compare.
You might like to try the 1zpresso Je-plus or the Bplus Apollo.
This type of burr set is known for producing a bimodal grind distribution, which creates a thick, intense, and sweet espresso profile, often compared favorably to traditional Italian espresso and milk drinks.

The Kinu M47 offers stepless micro-adjustment, with each full revolution having 50 divisions, resulting in a precision of approximately 5 microns per click, not 10 as mistakenly mentioned in some sources. This allows for extremely fine-tuned adjustments to achieve the perfect grind, which is crucial for dialing in espresso shots and brewing methods like French press or filter coffee.
Understanding the Kinu M47's Adjustment System
Stepless Adjustment:
Unlike grinders with fixed steps, the M47's design allows for continuous adjustment, providing actual control over the burr distance.
Precision:
The burr movement is so precise that the M47 can make adjustments as fine as 5 microns at each of the 50 divisions per full revolution.
Benefits:
This level of precision is especially beneficial for:
Espresso Dialing: It helps avoid over- or undershooting the sweet spot, giving you the control to repeatedly dial in your shots.
Brewing Stability: The consistent and repeatable settings ensure consistent brew quality day after day.
Grinding Dense Beans: It provides a smooth and stable grind, preventing the muddiness or astringency that can result from inconsistent settings when grinding difficult beans.
