High-Speed Performance | UC5105 CVD Grade | Gray Iron Specialist
Engineered for Maximum Surface Speed
UC5105 Grade (CVD Coating): UC5105 is the premier grade for High-Speed Turning of Gray Cast Iron. It features a specialized Alumina (Al2O3) coating with a refined grain structure that provides industry-leading resistance to crater wear and plastic deformation. This grade is designed for high-productivity environments where cycle time reduction is critical.
CNMG Geometry & Chipbreaker: This 80-degree diamond insert utilizes a multi-purpose chipbreaker optimized for cast iron. It effectively handles the unique chip formation of Gray Iron, preventing "powdering" from interfering with the tool life while providing four distinct cutting edges for maximum economy.
0.8mm (1/32") Radius: The 08 radius is the global standard for CNC turning. It offers excellent edge stability for semi-roughing while being capable of producing high-quality finishes at standard feed rates.

Shop DCLNR 12 HoldersPro-Tip: UC5105 vs. UC5115
UC5105 (The High-Speed King): Best for continuous finishing or semi-roughing of Gray Iron where tool life is limited by abrasive wear.
UC5115 (The All-Rounder): Best for general-purpose use, interrupted cuts, or when machining Ductile Iron that requires higher fracture toughness.
