Overview

The Key Mk.1 was our first foray into conical burr single-dose grinding and the SCAA 2021 Product of the Year.

The design of the Key centered around fitting a massive, 83mm conical burr set into the most compact, space-saving design possible. The burrs and mount define the Key's width, so it takes up a fraction of the space required by grinders with burrs only a fraction of the size.

While the Key Mk.1 is capable of grinding most roast levels for espresso, if you intend to grind light or nordic roasts for espresso at the lowest RPM, we recommend you take a look at the Key Mk.2 which was re-engineered to cut through the lightest, densest coffees no matter how fine the grind.

What is Renewed?

Renewed offers gently used Weber Workshop gear at discounted prices. Items may have minor cosmetic imperfections but are fully functional and perform like new.

All sales are final. Please read our Renewed Warranty promise before purchasing.

Key Features

Created by the engineers and designers behind the iPod nano, we took great care to pack a lot into a small package.

  • Built-in Cleaning Brush with Replaceable Head
  • Easy RPM Adjustment Knob
  • Compatible with both Standard (49mm & 58mm) and Magic (58mm) Tumbler Configurations
  • Magnetic Tumbler Centering on Hardwood Landing Pad
  • Tumbler configurations are interchangeable with our HG-2 Hand Grinder

83mm Burrs

The KEY is built around the massive 83mm conical burr set. We source our burrs exclusively from Mazzer, but apply our own unique secondary processes to partially season them so they are usable out of the box, and then seal in the edge with a life-prolonging and completely food safe TiN coating. Perfect for the single-dosing café or the home.

Items Included

Every KEY Grinder ships with the following in the box:

  • KEY Grinder Main Unit (SNOW or ONYX) 
  • Bean Feeder for KEY
  • No fuss plug-in-anywhere-in-the-world (90-240v). Ships with US-style 3-prong, but can use C13 cable (same as a computer) for localization in your country if needed.
  • Our proprietary food safe Titanium PVD-coated Mazzer burrs, installed and factory pre-aligned.
  • Magic Tumbler (Patented, fits 58mm) OR new Standard Tumbler (fits 49mm & 58mm)
  • Magnetic Hardwood Landing Pad
  • Hex wrenches for assembly and maintenance

The Key Mk.1

The Key's burrs and mount define its width, giving it the punch of Goliath with the footprint of David. That makes the Key the most precise, repeatable, and cleanable conical grinder in the world.

Magic Tumbler Wiper Installation

The Key with Magic Tumbler will arrive with the Magic Tumbler installed, but not the integrated Weiss Distribution Technique (WDT) wiper. We've put together the following video to help with installation. You'll need the included 5mm Hex Key included in the box, the included stainless steel retaining washer, the wiper itself, and a bit less than 5 minutes.

Maintenance and Cleaning

The KEY has been designed from the start to be both simple and easy to clean. No tools, and a full clean in seconds, not hours.

The upper funnel can be lifted away to reveal the top of the burr set. A few strokes with the brush that's always ready to deploy removes any stray coffee grounds. The lower funnel is held in place by 12 strong rare earth magnets and can be removed with a simple twist of the wrist. Once exposed, the lower burrs can be brushed clean in seconds.

We believe that a good product is a clean product, and designing them to be easy to clean is fundamental to improving the quality of your coffee and the hygiene of your countertop.
