CNMG 120412 T5115 indexable turning insert — Tungaloy, ISO-series, for turning

A CNMG120412 T5115 indexable insert for turning applications, designed for reliable chip control and long tool life in cast iron machining.

• CVD-coated carbide for long tool life
• Universal grade optimised for cast iron
• 80° rhombic geometry for versatile turning
• Double-sided chipbreaker, with central hole

Consistent cutting performance through controlled chip formation

The CVD-coated carbide grade T5115 combines wear resistance with edge stability to deliver longer tool life in abrasive workpieces. The insert’s double-sided chipbreaker promotes predictable chip formation, reducing interruptions from built-up edge and improving cycle time consistency. For turning operations in cast iron, this balance lowers tooling costs per component and reduces unscheduled tool changes, supporting steady production output.

Geometry engineered for repeatable, accurate turning

The rhombic outline with an 80° included angle and a 1.2 mm corner radius yields a balance of strength and versatility: the geometry enables secure engagement for general turning while allowing light chamfering or profile work where required. The insert’s rhombic form and 0° clearance facilitate compatibility with a wide range of holders, helping to maintain dimensional repeatability and surface quality on turned components.

System compatibility and practical handling in the tool room

As part of an ISO-series system, the insert is designed to fit compatible external holders or boring bars when form, clearance angle, tolerance class, fastening method, size and thickness match. The plate thickness of 4.76 mm and the cylindrical central hole ensure reliable clamping and simple indexing. Integrating this indexable insert into an established holder setup cuts setup time and streamlines inventory management for production workshops.

Clear material guidance and application advantages

Intended primarily for turning, the grade is a universal solution for cast iron, providing an operationally robust option where a balance between edge strength and wear resistance is required. The insert supports a wide range of turning tasks — from roughing to medium finishing — and its ISO conformity simplifies selection. If uncertainty remains about suitability for a specific job, supplementary technical data and machining parameters are available to aid the selection process.
