TNMA160408 UC5115
Mitsubishi Materials | The Cast Iron Turning Authority
The Mitsubishi TNMA160408 UC5115 is a robust CVD coated carbide insert designed for high-efficiency turning of cast iron. Utilizing the UC5115 grade with thick Al2O3 coating technology, this insert offers extreme thermal protection and crater wear resistance. The 0.8mm radius combined with a flat-top (No Chipbreaker) design makes it a top-tier long-tail industrial tool for heavy-duty machining of gray and ductile iron.

UC5115 CVD Grade
The UC5115 grade is a specialized CVD turning insert material featuring a thick alumina coating layer. This provides exceptional resistance to high-temperature oxidation and flank wear when machining abrasive cast iron. It is optimized for stable turning in continuous cutting conditions.
TNMA Flat-Top Geometry
The TNMA flat-top geometry is designed without a chipbreaker to maximize the edge strength of this indexable turning insert. Because cast iron produces brittle, segmented chips, the flat-top design ensures the tool can handle heavy loads without the risk of chipbreaker erosion or edge deformation.
