Compatibility
It is crucial to verify the compatibility of these burrs with your specific Sage/Breville coffee machine model. These burrs are specifically designed for models such as 870, 878, 880, 860, 840, 810, 450, and 500, particularly those with a "Pre 1926 PDC" designation and a 5-point lower burr design.
Important Compatibility Notes:
- These burrs are NOT suitable for older machines featuring non-adjustable burrs.
- These burrs are NOT compatible with Etzinger burrs, which typically use a 6-point lower burr design.
Before purchasing or installing, please compare your existing burr set with the images provided below to ensure a correct match. Pay close attention to the number of points on the lower burr.

Installation Guide
Replacing the burrs requires careful attention to detail. While the plastic assembly is not included with this set, the burrs are designed for straightforward installation into your existing assembly. For a visual guide, many users find online video tutorials helpful for the specific model of their Sage/Breville machine.
- Remove the Nut: Use a 10mm hex wrench to remove the nut securing the burr. Note that this nut is typically reverse-threaded, meaning you turn it clockwise to loosen.
- Release the Upper Burr: Gently pry the highlighted tab on the burr assembly to release the upper burr. This tab usually requires a flat screwdriver or similar tool to disengage.
- Replace Burrs: Carefully remove the old burrs and insert the new upper and lower burrs, ensuring they are seated correctly.
- Reassemble: Reattach the nut, turning counter-clockwise to tighten (due to reverse threading). Ensure all components are securely in place before operating the machine.

Maintenance
Regular maintenance of your burrs is essential for consistent grind quality and the longevity of your coffee machine. While these burrs are durable, proper care will ensure optimal performance.
- Regular Cleaning: Periodically clean the burrs to remove accumulated coffee oils and grounds. Use a stiff brush or a vacuum cleaner designed for small appliances. Avoid using water directly on the burrs.
- Grind Adjustment: Ensure your grind setting is appropriate for your brewing method. Incorrect settings can put undue stress on the burrs.
- Avoid Foreign Objects: Always ensure coffee beans are free of foreign objects (e.g., small stones) that could damage the burrs.
- Inspect for Wear: Over time, burrs will naturally wear down. If you notice a decline in grind consistency or an increase in grinding time, it may be time to inspect or replace your burrs.
Troubleshooting
If you experience issues after replacing your burrs or notice a decline in grinding performance, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent Grind Size | Burrs not seated correctly; residual old coffee grounds; burrs not fully tightened. | Re-check installation, ensure burrs are properly seated and tightened. Clean any remaining debris. |
| Grinder Jams or Slows Down | Excessive coffee oil buildup; foreign object in grinder; incorrect grind setting for beans. | Perform a thorough cleaning. Inspect for foreign objects. Adjust grind setting. |
| Poor Espresso Extraction / Taste | Grind size is incorrect (too coarse or too fine); burrs not performing optimally. | Adjust grind setting incrementally. Ensure burrs are clean and installed correctly. |
| Burrs Don't Fit | Incorrect burr type for your machine model (e.g., 6-point vs. 5-point lower burr). | Refer to the Compatibility section and verify your machine's burr type. These burrs are for 5-point lower burr systems. |
