TNMG220412 T5115 triangular turning insert — Tungaloy, CVD-coated carbide for turning

TNMG220412 T5115 is an ISO-form indexable turning insert designed for general turning applications, especially cast iron machining, offering a balance of wear resistance and edge stability.

• CVD-coated carbide grade T5115
• Designed for turning of cast iron
• Triangular 22 mm form with 60° angle
• Double-sided chipbreaker, reversible use

Stable cutting and material advantages for consistent cycle times

The insert combines a CVD coating with a carbide substrate, producing a wear-resistant surface that maintains a reliable cutting edge under interrupted or continuous cuts. The T5115 grade is developed as a universal solution for cast iron, offering an optimised trade-off between abrasive wear resistance and edge robustness. As a result, tool life is extended and workpiece quality remains consistent, which helps to reduce downtime and rework in series production. The balanced properties mean fewer tool changes and predictable replacement intervals for production planning.

ISO compatibility and secure clamping for quick tool changes

Built to the ISO indexable insert system, the triangular form and the cylindrical hole provide repeatable locating and secure clamping in a wide range of holders. Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness; the 22 mm dimension, 4.76 mm thickness and 60° insert geometry suit many standard external and internal turning holders. The double-sided chipbreaker allows the insert to be indexed and reused on the opposite face, reducing tooling costs and simplifying logistics for spares.

Choosing the right grade and optimising cutting strategy

For turning cast iron, the T5115 grade provides a pragmatic starting point: it combines edge stability with good wear resistance under typical cutting conditions. The insert’s 1.2 mm corner radius is suitable for general finishing and medium-duty profiling; for fine finishes or heavy interrupted cuts, select the matching chipbreaker and holder rigidity that fit the machine and setup. Although designed mainly for cast iron, the geometry and coating may perform acceptably on similar materials when feeds and speeds are adjusted. Specification-driven selection—matching chipbreaker, insert form and clamping—is the most effective route to repeatable results.

FAQ

Is this insert suitable for machining cast iron?
The TNMG220412 T5115 insert from Tungaloy is a universal grade developed for cast iron and offers a good balance of wear resistance and edge stability for typical cast-iron turning tasks.

How is the insert secured in the holder?
The insert uses a cylindrical hole for secure clamping; when mounted in a compatible ISO holder the TNMG220412 provides repeatable location and stable cutting performance.

Can the insert be indexed to present a fresh cutting edge?
Yes, the triangular form and double-sided chipbreaker permit indexing and reversal to access additional cutting edges, extending the usable life of each insert.

What does the T5115 designation indicate?
T5115 denotes the supplier’s carbide grade and coating strategy: a CVD-coated, universal grade optimised for cast iron with a focus on balanced wear resistance and edge stability.

Which geometrical data are most important when choosing a holder?
Critical dimensions include the insert size (22 mm), thickness (4.76 mm), corner radius (1.2 mm) and relief angle (0°); these determine fit, clamping and cutting behaviour in the holder.
