Gorilla Gear EK43 Black T4 Burrs (98mm)
The Gorilla Gear burrs for the EK 43 are fully machined to create an even and smooth surface from start to finish. Our EK 43 burrs have 4 pre-breaking teeth that aids in breaking down the coffee faster and easier, allowing the finishing area of the burr to deal with smaller sections of coffee and reducing the force needed to grind the coffee.
Turkish style cut for finer grinding, best for espresso and still with a great range for filter.
All Gorilla Gear burrs are pre-seasoned during the manufacturing process. Once pre-seasoned they are hardened and then treated with a low friction coating to drastically reduce surface friction. This aids in reducing equipment operating temperature, static and excessive heat.
Hardness - The life of your burrs is important to us, as well as using a high-quality tooling steel our burrs are also hardened.
Hardness - HV ( Vickers Pyramid Number )
Standard Steel Burrs - 800 HV
Gorilla Gear Black Burrs - 2,500 - 3,000 HV
Friction - Through thorough testing, we have been able to gain higher extractions and clarity in the cup through reducing surface friction. Our low friction coating is the final stage of production and also gives our burrs a stunning black finish.
Friction Factor
Standard Steel Burrs - 0.8-1.0
Gorilla Gear Black Burrs - 0.1
