The Rocket R58 “Cinquantotto” is the most popular dual boiler coffee machine sold by Rocket. The secret for its success is simple: high quality, incredible looks and packed with the latest technology. Now on its 3rd generation, this coffee machine has a totally re designed PID with multiple functions.

Overview

About the product:
The Rocket R58 Cinquantotto, Italian for “58”, is Rocket’s flagship dual-boiler espresso machine, hand-built in Milan. Separate brew and steam boilers let you pull shots and steam milk at the same time, while a heated E61 group head and PID control keep temperatures rock-steady. A quiet rotary vane pump delivers café-quality pressure, and the clean stainless body suits any kitchen.
How to use:
  • Switch on, or schedule the auto-on timer so it is up to temperature before you wake.

  • Set brew and steam temperatures on the PID display.

  • Grind, dose, and tamp into the 58 mm portafilter, lock it in, and start the shot.

  • Use the steam wand for milk, and power off the steam boiler if you only drink espresso.

The Weber Workshops Key Mk.2 is a compact coffee grinder with 83 mm conical burrs finished with a food-safe TiN coating, for consistent grinding across espresso and filter brews. It adds an RPM adjustment knob, 50% more torque, a roughly 40 g loading chamber with magnetic dust cover and 5-micron stepped adjustment. Includes Magic Tumbler, blower, RDT bottle and stainless steel dosing cup.

The Key Mk.2 from Weber Workshops redefines what a compact, high-performance grinder can be.  

Building on the legacy of the original Key, the Mk.2 maintains the same ultra-efficient footprint while introducing major improvements in workflow, usability, and precision. 

At the heart of The Key is a massive 83mm conical burr set, originally manufactured by Mazzer and then enhanced by Weber’s unique treatment process, including pre-seasoning and a food-safe TiN coating. 

This ensures optimal performance right out of the box, delivering outstanding grind consistency and flavor clarity across espresso and filter brews. 

Despite housing such large burrs, The Key’s design remains impressively space-saving. 

Designed by the team behind the iPod Nano, every detail is engineered for performance and elegance. 

New in the Mk.2 is an integrated cleaning brush with a solid oak handle, brass ferrule, and replaceable bristle head, neatly stored via a hidden magnet. Also added is an intuitive RPM adjustment knob, allowing users to fine-tune motor speed for different brew styles. 

The Key Mk.2 features a 50% increase in torque compared to the original model, thanks to a new gearing system and upgraded power supply—allowing it to grind even the lightest roasts with ease. 

A redesigned magnetic dust cover now sits atop a 30% larger loading chamber with approximately 40g capacity, making dosing cleaner and more efficient while preventing coffee fragments from escaping. 

Grind adjustment is simple and precise, thanks to 5-micron stepped settings, allowing you to move seamlessly from Turkish-fine to pour-over ready. 

Every KEY Mk.II Grinder ships with the following in the box:  

  • KEY Grinder (SNOW or ONYX)   
  • No fuss plug-in-anywhere-in-the-world (90-240v) C13-type power cable (US, AU, EU, UK styles only)
  • Magic Tumbler & Lid (Patented, fits 58mm)
  • Air blower bellows for cleaning
