Weber Workshops EG-1 Mk.3 Coffee Grinder with Core Burrs

Precision single-dose grinding with 80 mm flat burrs for espresso and filter coffee.

The EG-1 Mk.3 is built for serious home baristas and professionals who want one grinder that handles both espresso and pour-over. Its 80 mm hardened-steel CORE flat burrs cover the full grind range, and 5-micron adjustment steps let you move between brew methods without purging or recalibrating. Variable RPM control and a tool-free magnetic grind chamber give you full control and quick cleaning.

Key Features

• 80 mm CORE flat burrs: hardened steel for a uniform grind from espresso to filter.
• 5-micron adjustment: precise, repeatable settings for fast switching between brew methods.
• Variable RPM (500–1800): tune grind speed to the coffee, roast, or workflow.
• Magnetic burr mount: no screw holes to trap old grounds; burrs come out quickly for cleaning.
