Porlex Grinder Spare Parts Part:Inner Burr Both items are built withExtend the life of your manual coffee grinder with spare parts from fresh Ceramic Burrs for Porlex grinders to handles and grinds cups. The conical burrs are built with the same durable ceramic that the grinders ship with brand new. Dull and chipped grinders produce inconsistent grounds, which results in unbalanced coffee. A new set of burrs is the solution. We suggest replacing the burrs every 12 18 months, or when the burrs become dull or damaged.
