Material & Geometry Mastery
UC5115 Coating Technology
The UC5115 CVD grade is engineered for extreme wear resistance. Its thick Alumina (Al2O3) coating provides a superior thermal barrier, allowing for stable, high-speed dry machining of abrasive cast irons without the risk of plastic deformation.
MA Chipbreaker Logic
The MA (Medium-range) chipbreaker is the workhorse of the industry. With a 1.2mm radius, the DNMG150612 version offers enhanced edge security, preventing chipping even during light interrupted cuts or when dealing with scaly cast iron surfaces.
