Add to Wishlist


The EK 43 has been the modern go-to grinder for filter coffee & single dose espresso for a little while now, coffee pro’s have been tweaking & modifying them, painting & printing custom dials to individualise & push the boundaries of coffee brewing.

It was only a matter of time before it was taken a step further, the Gorilla Gear Black G4 for the EK 43 are fully machined creating an even and smooth surface from start to finish.

The G4 refers to the 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.

All Gorilla Gear burrs are pre-seasoned during the manufacturing process.

Once pre-seasoned they are hardened, post-hardening the burrs they are then treated with a low friction coating to drastically reduce surface friction. This aids in reducing equipment operating temperature, static and excessive heat.

The life of your burrs is important and as well as using a high-quality tooling steel, after their custom pre-seasoning treatment the burrs are also hardened.

Standard Steel Burrs - 800 HV

Gorilla Gear's aim is to produce products that aid in attaining as close to a unimodal grind as possible.

Through thorough testing, Gorilla Gear have been able to gain higher extractions and clarity in the cup through reducing surface friction. Their low friction coating is the final stage of production and also gives their burrs a stunning black finish.
