TNMG220412 T6215 — ISO triangular indexable turning insert for turning, CVD-coated carbide, Tungaloy

TNMG220412 T6215 is an ISO triangular indexable insert designed for efficient external and internal turning of stainless steels under stable to slightly interrupted conditions

• CVD-coated carbide grade T6215
• For turning stainless steels
• 60° triangular TNMG form
• Double-sided chipbreaker, cylindrical hole

Higher productivity through wear‑resistant CVD coating

The CVD‑coated carbide grade T6215 provides elevated wear resistance and a predictable flank‑wear progression when machining stainless steels, which helps to extend edge life and reduce unplanned tool changes. The coating and substrate combination is optimised for stable to lightly interrupted cuts, delivering consistent surface finish and dimensional accuracy. The reversible design contributes to a favourable cost per cutting edge and supports continuous production without frequent tool replacement.

Precise fit and reliable clamping for repeatable processes

The insert follows ISO conventions for form, clearance and size, offering a 60° triangle geometry and standard mounting interface that ensure compatibility with matching external holders or boring bars. Correct selection of holder form, clearance angle, tolerance class, fastening and thickness is essential for secure seating and vibration‑free cutting. This standardisation simplifies tool selection and enables straightforward integration into existing tool systems while maintaining process reliability.

Improved chip control and stable cutting for fewer interruptions

The double‑sided chipbreaker combined with the cylindrical hole design supports efficient chip formation and evacuation, reducing the risk of built‑up edge and improving surface integrity. In practice, this results in fewer interruptions, lower rework rates and better predictable cycle times. If uncertainty exists about the optimal chipbreaker or grade for a specific application, technical consultation is available to match the insert characteristics to workpiece material and machining stability.

Robust geometry and versatile application scope

With a corner radius of 1.2 mm and a plate thickness of 4.76 mm, the insert offers a balance between edge strength and achievable surface finish for a range of turning tasks. The triangular TNMG shape enables three indexable edges per face and economical use of the insert body. Intended for both external and internal turning, the insert is part of an ISO turning insert system that requires a compatible holder, shim/clamping set and replacement screws to form a complete cutting system suitable for production environments.

FAQ

What materials is this insert best suited for?
The TNMG220412 T6215 insert is designed primarily for machining stainless steels, offering wear resistance and stable performance under steady to lightly interrupted cutting conditions.

How many cutting edges are available per insert?
Due to its double‑sided TNMG geometry, the insert provides multiple indexable edges; the reversible design increases usable edges and improves cost efficiency per edge.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; matching ISO‑compliant external holders or boring bars is recommended for secure seating.

What benefits does the CVD coating deliver?
The CVD‑coating on grade T6215 enhances wear resistance and thermal stability, leading to longer edge life, consistent surface finish and fewer tool changes during production.

Is this insert suitable for interrupted cuts?
The grade T6215 and the insert geometry are intended for stable to slightly interrupted conditions; for heavy interruptions, a dedicated geometry or different grade should be considered.
