Mitsubishi Materials | The Specialist for High-Efficiency Cast Iron Turning
The Mitsubishi TNMA160412 UC5115 is a heavy-duty CVD coated carbide insert engineered for high-performance turning of Gray and Ductile Cast Iron. Utilizing the UC5115 grade with optimized alumina coating, this insert provides extreme thermal protection and crater wear resistance. The 1.2mm nose radius combined with a flat-top (No Chipbreaker) design makes it the definitive long-tail industrial tool for high-feed roughing and stable finishing in K-class materials.

UC5115 CVD Turning Grade
The UC5115 grade is a specialized CVD turning insert material featuring a thick layer of Al2O3. This provides superior heat insulation when machining abrasive cast iron. This grade is optimized for stable turning in high-speed, continuous cutting conditions where flank wear resistance is vital.
TNMA Flat-Top Geometry
The TNMA geometry is a flat-top design (no chipbreaker) that provides maximum cross-sectional strength for this indexable turning insert. Because cast iron produces brittle chips, the flat-top design is ideal, offering a robust edge that resists chipping even under heavy interrupted loads or variable casting skins.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
