The Black Diamond Blind Upper Burrs by Eureka are an upgrade for your coffee grinder.

• 65 mm burrs with cryogenic treatment and DLC (Diamond-Like Carbon) coating, for up to +90% longer lifespan compared to standard burrs.
• Geometric profile: All Purpose (Turkish, Espresso, Moka, Filter, Cold Brew).
