Introducing the Hypernova Ultra Burr set for improved top end range for espresso particle distribution at finer sizes. Medium body, increased clarity and high definition of flavour, improved balance and a high acidity. 440 Stainless Steel Base material improves edge hardness to HRC65. An extra process is added to polish the burr on a micron level to remove any tiny imperfections and an added dual coating titanium and thermal plasma is added to create an edge hardness of HRC67. Features Durability & Heat Sinking. The plasma coated burrs will have an increase in durability and also heat resistance. The burrs will stay cooler on the cutting edge during grinding and as a result this will impact the overall durability and sharpness of the cutting edge. Grind Consistency. The hypernova ULTRA has an updated pre-crushing geometry and the plasma coating helps to achieve a much shorter grind time. The plasma coating will also offer an improvement to the consistency of particle sizes. Extra finishing process to remove surface imperfections. Coated with a thermal plasma spray technology. Improved top end range for espresso particle distribution at finer sizes. Medium body, vibrant clarity and definition, balanced profile and higher acidity.
