64mm 12th Inner Big Breakers Flat Burr: Original SUS420J2, TiN Gold & TiCN Gray Black Coatings,which the surface treatment best ?
You could see the anotations between three of them before making a selection.
When building a high performance coffee grinder, burr geometry and material coating directly determine grinding consistency, heat generation, service life and final cup flavor. Our 64 mm 12th flat burr uses the same core geometry for all three variants — Original SUS420J2, TiN Gold coating, and TiCN Gray Black coating — giving users flexible choices for home hobby, heavy use home and commercial cafe environments.
Base Raw Material: Original SUS420J2 (3Cr13)
Made of SUS420J2 (3Cr13) high-hardness, high-toughness, high-quality stainless steel, ours own specialized precision machinery ensure the coarse and the fine tooth profile maintains consistent and smooth flow lines from the inside to the outside.
Key features
- Pure metal silver finish, no surface coating applied.
- Classic durability, reliable for daily home level workloads.
- Reveals the original cutting character of the 12th Big Inner Breaker teeth flat profile: produces flaky shaped grounds, great for unlocking bright acidity from light to medium-to-dark roasted beans.
- Best for home users with moderate grinding volume, who prefer natural steel performance and cost effective replacement.
- Extremely high powder output efficiency, with excellent powder fineness uniformity , extremely extraction effect , Distinctive flavor layers .
- Note: Without a hard coating, the cutting edges will experience normal wear under high-volume, continuous commercial use.
TiN Gold Coated Burr (Titanium Nitride)
TiN is the well known golden hard coating widely adapted from machining cutting tool technology onto coffee grinding burrs. Deposited on top of SUS420J2 substrate.
Key features
- Distinctive bright gold metallic appearance.
- Higher surface hardness than bare steel, improves wear resistance and extends usable burr life.
- Lower surface friction during grinding: smoother rotation, less frictional heat build up, higher efficiency grinding performance.
- Excellent for espresso focused setups, consistent fine grinding performance for regular home or light cafe workload.
- Taste benefit: reduced grinding heat helps preserve bean aroma compounds during high frequency espresso grinding.
TiCN Gray Black Coated Burr (Titanium Carbonitride)
TiCN is an upgraded high hardness composite coating, appearing in matte gray black tone. It sits at the top tier among these three options for heavy duty usage.
Key features
- High hardness surface treatment, significantly higher hardness value than TiN and bare SUS420J2 steel.
- Ultra low friction coefficient, minimizes heat accumulation even under continuous high volume commercial grinding. Less heat means your coffee flavor stays intact, no burnt or baked notes from over heated grounds.
- Outstanding anti abrasion performance, greatly prolongs burr service life for busy cafe, roastery or heavy use homee baristas.
- Maintains the original 12th tooth flat burr particle distribution, only improving surface physical properties without altering the fundamental grinding geometry.
How To Choose Between The Three
- Pick Original SUS420J2: If you are a home coffee enthusiast with medium daily output, want original steel cutting character and budget friendly spare burrs.
- Pick TiN Gold Coated: For home espresso lovers or small volume cafes, seeking better wear resistance and cooler grinding with attractive visual finish.
- Pick TiCN Gray Black Coated: For commercial cafes, roasteries, heavy usage home users. Prioritize maximum service life, minimal grinding heat and stable long term grinding precision.
Important note: All three burrs share exactly the same 64 mm 12th Big Breaker tooth flat geometry. Coatings enhance surface hardness and friction performance; they do not change the core particle cutting profile of the burr set. Your bean flavor foundation comes from the burr tooth design, while coatings protect sharpness over time.
Final Summary
This 64 mm 12th inner big breakers flat burr series gives one geometry with three material coating tiers. Starting from proven SUS420J2 stainless steel, upgraded TiN gold coating, up to top spec TiCN gray black heavy duty coating. Whether you are a home barista or running a coffee business, there is a suitable version to match your grinding volume, budget and flavor pursuit.
While specific steps can vary slightly by model (e.g., Barista Express, Pro, Dual Boiler), the process for replacing the 44.6mm conical burr set (the upper and lower burrs) is generally the same for most Breville espresso machines.
Important: Before starting, unplug the machine. You will likely need a flathead screwdriver, a Phillips head screwdriver, and a 9mm or 10mm wrench (or socket).
