The KEY – Mk.2
83mm Conical Burr Electric Grinder
Overview
From espresso to filter coffee preparation, the KEY is Weber Workshops’ compact 83mm conical burr single dose grinder for specialty coffee. The Mk.2 builds on the original with a series of workflow and usability upgrades, while keeping the same tight footprint on the counter.
Built around a massive 83mm Mazzer conical burr set with Weber’s own secondary processing and food-safe TiN coating, the KEY is made for those who want the body, texture and ease of a conical burr grinder without sacrificing precision or repeatability. It is a grinder that feels small in footprint, but serious in every other sense.
With features like easy RPM adjustment, 5 micron stepped adjustment, a built-in cleaning brush, and magnetic tumbler centering on a hardwood landing pad, the KEY is designed to make a high-end single dose workflow feel fast, clean and considered.

The KEY is available in Snow and Onyx.
