Equipped with the Commandante C40 MK3 Nitro Blade Coffee Grinder Red Sonia C40 Nitro Blade, Comandante is a new level of professional coffee hand mills and further improve its proven quality. The new factory grinder is completely made of stainless steel which is manufactured with a patented process. The result is a very durable material with knife steel quality. The end of the grinding disc is hardened and "cut" after the coffee beans are sharpened. Thanks to the unique grinding technology, this mill produces extremely precise and consistent grinding results with virtually no "fine powder" at every grinding degree. The power transmission during grinding is best and the double ball bearings make crank smooth. Repeat, but it indicates that the professional works. The Comandante development team focuses on key abilities and attention to detail. The result is a "Germany" hand mill. The heart of this mill is a high nitrogen martensite stainless steel grinding machine with high hardness (about 58 Rockwell) and high toughness for high edge retention. After curing, the super sharp Z blade becomes sharp. The newly developed grinding machine has a very consistent grinding result. Grinding speed about 1 rotation/rotating sealed axle, double bearing with stainless steel ball bearings The crank knob made of oak wood is removable and secured with crank pressure lock. The magnetic connection secures the crank to the axle. Eastman Tritan copolyester all plastic parts
