Cast Iron Specialist | UC5115 Abrasive Resistance | 55° Diamond
High-Performance Turning in Cast Materials
UC5115 Grade (The Iron Workhorse): The UC5115 is Mitsubishi's premium CVD grade specifically optimized for Gray and Ductile Cast Iron. It features a specialized thick-film coating technology that provides exceptional resistance to flank wear and cratering. This grade is designed to handle the abrasive nature of graphite and the heat generated during dry high-speed machining.
DCMT Geometry (Positive Profile): The 55-degree diamond shape provides high versatility for profiling, facing, and longitudinal turning. The positive rake angle lowers the cutting force, which helps prevent "break-out" at the edge of brittle cast iron workpieces and reduces heat transfer to the tool holder.
0.4mm Radius (Precision Precision): The 0.4mm (04) radius is the perfect balance for finishing. It provides a sharp enough edge to prevent chatter in slender components while remaining robust enough to withstand the micro-shocks of abrasive cast iron surfaces.

UC5115 (Iron Specialist): Engineered for abrasion resistance. High Speed + Iron = UC5115. Using this on steel will cause rapid chemical wear.
US735 (Stainless Specialist): Engineered for toughness. If your material is Stainless Steel or has high-impact interrupted cuts, switch to US735.
