Mazzer 64mm Flat Burrs: Key Parts for Commercial Grinders

If your espresso shots taste inconsistent or your pour-over brews lack clarity, the issue might not be your technique—it could be the burrs. In any commercial or high-use coffee grinder, the burrs are just as critical as the motor. They’re the part that physically grinds the beans, directly shaping particle size, extraction yield, and ultimately, flavor.

Mazzer’s 64mm flat burrs, made by Italian manufacturer MAZZER and stamped with the official logo, are a go-to upgrade or original part for grinders like the Faema 900N and Xima JX-600. These burrs measure 64mm in diameter and are built for heavy-duty use in coffee shops.

What Are Flat Burr Grinders and Why Do They Matter?

Flat burr grinders use two parallel, horizontal rings—one stationary, one rotating—to crush coffee beans into uniform particles. This design is favored in specialty coffee for producing a more even grind size, which leads to balanced extractions. Unlike conical burrs, flat burrs tend to highlight clarity and brightness in the cup, making them ideal for single-origin pour-overs and precise espresso blends.

The Role of Burr Size and Material

The 64mm measurement refers to the diameter of the burr discs. This size strikes a balance between grind consistency and throughput, making it common in both commercial and high-end home machines. Mazzer’s 64mm flat burrs are made from high-quality steel and are designed to maintain sharpness over long production cycles. Their construction directly impacts how finely or coarsely your coffee is ground, influencing factors like surface area, extraction speed, and flavor profile.

Compatibility with Popular Grinder Models

These MAZZER 64mm flat burrs are not only original equipment for certain Mazzer models, but are also compatible with other widely used commercial grinders. Specifically, they can be used to upgrade or replace parts in the Faema 900N and Xima JX-600. Whether you're maintaining a workhorse machine or upgrading an older unit, these burrs help restore or enhance grind precision.

The burrs are sold as original MAZZER-manufactured parts, ensuring authenticity and reliability. If you’re managing a coffee shop or maintaining multiple grinders, using OEM or compatible 64mm flat burrs can keep your equipment performing at its best.

Frequently Asked Questions

What is a 64mm flat burr?

A 64mm flat burr is a type of coffee grinder burr that measures 64mm in diameter, featuring two parallel, flat grinding rings. It is designed to produce uniform coffee grounds and is commonly used in commercial and high-end espresso grinders for its balance of grind consistency and output capacity.

Are Mazzer 64mm burrs compatible with the Faema 900N?

Yes, Mazzer 64mm flat burrs are compatible with the Faema 900N, as well as the Xima JX-600. They can be used as original parts or as upgrades to improve grind consistency and performance in these machines.

What’s the difference between flat burrs and conical burrs?

Flat burrs use two parallel, horizontal discs to crush beans, typically producing a more uniform and consistent grind suited for bright, clear flavors. Conical burrs use a cone-shaped burr inside a ring, often resulting in slightly faster grinds with more body and less clarity.

Why are burrs important in coffee grinding?

Burrs are the part of the grinder that actually breaks down the coffee beans. Their shape, size, and sharpness determine the uniformity of the grind, which directly affects extraction, flavor, and aroma. High-quality burrs ensure consistency shot after shot or pour-over after pour-over.

Can I upgrade my grinder with Mazzer 64mm burrs?

Yes, if your grinder model—such as the Faema 900N or Xima JX-600—is compatible, upgrading to Mazzer 64mm flat burrs can improve grind quality, consistency, and overall brewing performance. Always check compatibility with your specific machine model.
