Mitsubishi Materials | The Specialist for High-Efficiency Cast Iron Turning
The Mitsubishi TNMG160412 UC5115 is a high-performance CVD coated carbide insert engineered for heavy-duty turning of Gray and Ductile Cast Iron. Utilizing the UC5115 grade with a thick Alumina ($Al_2O_3$) layer, this insert provides extreme thermal protection and crater wear resistance. The large 1.2mm nose radius makes it a definitive long-tail industrial tool for high-feed roughing and stable finishing in abrasive K-class materials.

UC5115 CVD Turning Grade
The UC5115 grade is a specialized CVD turning material. It balances extreme hardness with enough toughness to handle light interruptions. This indexable turning insert is the first choice for machining cast iron components where heat-induced wear is the primary concern.
TNMG Robust Geometry
The double-sided TNMG geometry provides 6 usable cutting edges, offering excellent cost-performance for CNC machining. The 1.2mm radius on this model ensures the cutting edge remains stable under high feed rates, reducing the risk of edge chipping on abrasive casting skins.
Recommended Cutting Parameters
