CNMG160612 T5115 Turning Insert for Turning by Tungaloy

The CNMG160612 T5115 Tungaloy insert is an ISO‑standard turning indexable insert designed for external and internal turning, offering a universal grade optimised for cast iron machining.

• CNMG160612 geometry, ISO‑standard insert
• CVD-coated carbide grade T5115
• Double-sided chipbreaker for cast iron
• 80° rhombic shape with 1.2 mm nose radius

Reliable, wear‑resistant grade for cast iron turning

The T5115 grade is a CVD‑coated carbide developed as a universal solution for machining cast iron, combining wear resistance with edge stability. This balance reduces unexpected tool wear and extends time between indexings, which contributes to fewer interruptions in production. The coating supports consistent surface quality and helps to maintain a stable cutting edge under typical turning conditions, making the insert well suited where reproducible component quality and predictable tool life are priorities.

Clear compatibility and mounting requirements for trouble‑free setup

The insert follows ISO geometry rules, so compatibility with a clamping holder depends on formal parameters such as form, clearance angle, tolerance class, fastening, size and thickness. The CNMG160612 features a rhombic plate form with an 80° lead angle, a 0° clearance angle and a 6.35 mm plate thickness; it also has a cylindrical hole for secure fastening. These measurable values make it straightforward to match the insert to a suitable outer holder or boring bar: select a holder that matches the geometry and tolerance class to ensure correct seat, clamping force and repeatability.

Productivity gains through stable chip formation and simple system integration

A double‑sided chipbreaker design gives a practical combination of tool life and chip control, particularly in cast iron applications where chip formation affects both surface finish and machine cleanliness. The 1.2 mm nose radius provides a compromise between strength and surface finish, supporting medium to heavier feeds while maintaining acceptable component quality. The recommended system comprises the ISO insert, a matching external holder or boring bar, an underlay/clamping set and replacement screws; this modular approach simplifies inventory and shortens changeover times, supporting productive machining cycles.

FAQ

What materials is this insert best suited for?
The CNMG160612 with grade T5115 is optimised as a universal choice for cast iron, offering a compromise between wear resistance and edge stability that supports consistent performance in typical turning operations.

How is compatibility with a holder determined?
Compatibility depends on matching the insert geometry and measurable parameters: form, clearance angle (0°), tolerance class, fastening, size (16 mm) and thickness (6.35 mm); selecting a holder that aligns with these values ensures correct clamping and repeatable results.

What advantage does the double‑sided chipbreaker provide?
A double‑sided chipbreaker enables indexing of multiple cutting edges and improves chip control for cast iron turning; this can increase effective tool life and simplify tool management in a production environment.

Which dimensions are most important when specifying this insert?
Key dimensions are the plate designation CNMG160612, thickness 6.35 mm, nose radius 1.2 mm, lead angle 80° and the cylindrical hole style; these values are essential for choosing a compatible holder and ensuring correct seating.

Can the insert be used for internal as well as external turning?
Yes, the ISO‑standard geometry and the balanced characteristics of the T5115 grade make it suitable for both external and internal turning operations when paired with an appropriate holder.
