What Is the KINGrinder K6?
The KINGrinder K6 is a manual hand coffee grinder. You turn the handle by hand to grind coffee beans fresh every time. This one comes in iron gray color with a straight handle. It has big 48mm stainless steel conical burrs (the parts that crush the beans). These burrs have a special 7-sided shape that makes grinds very even.
It contains 25-35 grams of beans- enough to make one large cup of coffee or 2 small cups. The interesting thing about this hand coffee grinder is that it’s composed of powerful aluminum and steel thus it is solid and durable. How fine or coarse the grind is is also adjustable using a dial which clicks in just -16 microns (very small!).
There are 60 clicks in one full turn, and you can go from super fine (for espresso) to coarse (for French press).
It comes with a brush for cleaning and a little card that shows good settings for different ways to brew coffee.

My Experience – How I Tested It
I got this hand coffee grinder a few months ago because my old cheap grinder made uneven bits that ruined my coffee taste. I use it almost every day for pour-over and AeroPress.
First, I tried it with medium roast beans. I set it to about 90-100 clicks for pour-over in the hand coffee grinder . Grinding 20 grams took me around 40 seconds – not too hard, and the handle feels smooth because of the bearings inside.
The grounds looked super even – no big chunks or too much powder. When I brewed my coffee, wow! It tasted brighter, sweeter, and fuller than before. No more bitter or weak cups. The flavor pops – like fruit notes in light roasts come out strong.
I also tried it for espresso (around 40 clicks). It works well – my shots had good body and less sour taste. For French press (120+ clicks), the coarse grounds were perfect, no mud at the bottom.
Cleaning is easy. I dismantle it by hand (no tools required), sweep the grounds and reassemble. I do it following every consumption so that it remains fresh. It takes 1-2 minutes.
Weeks after using it on a daily basis, it remains new. No loose parts or rust (I keep it dry). Some people on Reddit say they used it for over a year with no big problems.
