Description Details

The Astoria 28003421 Grinding Burrs Set is a premium replacement component engineered to restore the precision and consistency of your commercial espresso grinder. Featuring a substantial 68mm diameter, these flat burrs are crafted from high-grade hardened steel to ensure long-lasting sharpness and heat resistance during high-volume operations. By installing this genuine Astoria part, you ensure a uniform particle size distribution, which is essential for achieving the perfect extraction and full flavor profile from your coffee beans.

Designed for durability and professional performance, the Ø 68 Grinding Burrs Set (Part #28003421) helps maintain the operational efficiency of your grinding equipment. Over time, dull burrs can lead to inconsistent grind sizes and increased heat generation, which can negatively impact the aroma and taste of your espresso. Replacing worn blades with this specialized set reduces motor strain and improves the speed of the grinding process, making it an ideal choice for busy cafes and specialty coffee shops looking to minimize downtime and maintain high quality standards.

This 68mm burr set is specifically compatible with the Astoria Supra 68 series and corresponds to part number C00046014. These burrs are easy to install as part of a routine maintenance schedule, ensuring your grinder remains at peak performance. Technical specifications include a 68mm outer diameter and precision-cut teeth designed for fine espresso grinding. Choosing authentic Astoria components from Kaldi.com guarantees a perfect fit and preserves the longevity of your equipment, keeping your coffee service running smoothly and consistently.
