TNMG220412 T5125 — TNMG indexable insert for turning, CVD‑coated carbide, 60° (Tungaloy)

A TNMG220412 T5125 indexable insert engineered for external and internal turning, optimised for interrupted cuts and cast iron applications.

• ISO‑standard triangular insert, 60° geometry
• CVD‑coated carbide for durable edge life
• Double‑sided chipbreaker for cast iron
• Cylindrical‑hole design for secure clamping

Greater productivity through wear‑resistant cutting performance

The CVD‑coated carbide grade T5125 offers a balance of toughness and wear resistance that suits less stable machining conditions. This characteristic reduces edge chipping during interrupted cuts and extends tool life, which in turn lowers changeover frequency and improves uptime. Emphasising productive cutting, the coating protects the cutting edge at elevated temperatures and maintains a consistent flank wear rate, translating into predictable tool consumption and easier process planning.

System compatibility and secure clamping for consistent results

Built to the ISO indexable insert system, the triangular 60° form and cylindrical hole require holders matched by shape, clearance angle, tolerance class, fastening type, size and thickness. The insert’s 4.76 mm thickness and 22 mm size combine with the 1.2 mm corner radius to provide a stable contact area and repetitive seating. Using the correct holder, underlay and clamping set ensures that the insert indexes cleanly and that every reindex preserves the intended geometry, so part tolerances remain consistent across production runs.

Better chip control and process reliability for cast iron turning

The double‑sided chipbreaker and the selected T5125 grade are optimised for cast iron machining and deliver improved chip control and surface integrity in many turning operations. By matching the chipbreaker and grade to the workpiece and machining stability, the insert helps reduce vibration and promotes a steadier cutting force, which benefits cycle times and surface finish. The insert’s robust edge and repeatable indexing support predictable results, aiding quality assurance and reducing scrap rates.

FAQ

Is this insert suitable for cast iron turning?
Yes. The T5125 grade and the double‑sided chipbreaker are specified for cast iron, especially where interrupted cuts or less stable conditions occur.

Which holder characteristics must match the insert?
Compatibility depends on holder form, clearance angle (0° specified for this insert), tolerance class, fastening type, size (22 mm) and plate thickness (4.76 mm); the system must accommodate a triangular 60° geometry and the cylindrical hole.

Can this insert be used for both external and internal turning?
The insert is designed for both external and internal turning applications when used with an appropriate external holder or boring bar and the correct clamping set.

What benefits does the CVD coating provide?
The CVD‑coated carbide offers improved high‑temperature wear resistance, a more stable cutting edge under heat, and enhanced performance in continuous and interrupted cutting regimes.

How does the geometry influence surface finish and productivity?
The 60° triangular shape and 1.2 mm corner radius provide a compromise between robust edge strength and achievable surface finish; when matched with the right feeds and speeds, the insert helps maintain cycle time while delivering consistent part quality.
