La Marzocco Swift Ceramic Grinder Burr Set One matched set of ceramic burrs for the La Marzocco Swift espresso grinder, ceramic burrs run cooler than steel and hold their edge longer under heavy daily volume. SPECIFICATIONS Ceramic construction Sold as a matched set COMPATIBILITY Fits: La Marzocco Swift espresso grinder INSTALLATION Burr replacement is a technician-recommended job, proper seating and dose recalibration after the swap matter for consistent extraction. PRO TIPS Ceramic burrs are more heat- and wear-resistant than steel but also more brittle, never run the grinder empty or let a foreign object (staple, small stone) pass through, since ceramic burrs chip rather than dull gracefully. For more on when to replace burrs and how to tell they're worn, see Espresso Parts' grinder burr maintenance guide.
