The KINGrinder K4 and K6

For our tests, two models stand out:

KINGrinder K4 and K6 Tests

We tested these two models under different conditions.

Handling

• Sturdy aluminum body with non-slip rubber grip
• 60-click adjustment ring, easy to operate
• Screwed container with large thread pitch, solid and durable

The Crank

• Attached to a plastic cap allowing the grinder to be closed
• Ergonomic wooden handle
• Special feature: detachable cap for use with a drill

The Container

• Heavy and stable metal container (unlike the lightweight plastic of the Kinu M47 Phoenix)
• No internal edges → prevents ground coffee from being retained

Disassembly

Disassembly is complete but technical. Less simple than a 1Zpresso Jmax, but it allows for thorough cleaning.
