TNMG160408 T6215 Tungaloy indexable turning insert — 60° triangular form, CVD-coated carbide

A TNMG160408 Tungaloy insert designed for ISO-standard turning tasks, optimised for external and internal turning of stainless steels under stable to lightly interrupted conditions.

• ISO-standard triangular insert, 60° geometry
• CVD-coated carbide for wear resistance
• 0.8 mm corner radius for versatile profiles
• Suitable for stainless steel machining

Consistent machining performance for stainless-steel turning

The insert delivers stable cutting when machining rostfreier Stahl, thanks to the T6215 CVD coating that enhances wear resistance and edge life. In practical terms, this means fewer insert changes and more continuous runtime on medium-duty turning operations. The triangular, 60° geometry provides predictable chip formation and simple indexability, making it a reliable choice for workshops seeking steady cycle times and reproducible surface quality. The construct is particularly beneficial where uninterrupted surface finish and dimensional stability are required.

Clear compatibility and straightforward system integration

Compatibility with holders depends on form, clearance angle, tolerance class, fixing method, size and thickness; this insert follows the ISO-DIN convention for turning plates and fits common external holders or boring bars that accept TNMG-style inserts. The 0° clearance angle and the specified plate thickness ensure mechanical stability in the clamped assembly, while the central cylindrical hole secures the insert against rotational and axial movement. Selecting the correct holder and screw set completes the system and simplifies procurement and stocking in production environments.

Coating and substrate: durability where it matters

The cutting material is cemented carbide with a CVD coating (T6215) that is engineered for enhanced wear resistance when cutting rostfreier Stahl. The chemical vapour deposition layer provides a hard, adherent surface that reduces flank wear and edge chipping under stable or mildly interrupted cuts. For machining stainless steels, this combination helps control work-hardening effects and supports repeatable tool life — an important factor when aiming for consistent batch-to-batch results or long production runs.

Practical benefits for process reliability and handling

With a 0.8 mm corner radius, the insert balances toughness and the ability to generate robust part geometry without excessive cutting forces. The double-sided chipbreaker and triangular form allow economical indexing and reduce tooling costs per part. When paired with a suitable holder and correct cutting parameters, this insert supports predictable chip control and stable cutting forces, contributing to higher first-pass yields and reduced rework. The ISO-standard nomenclature simplifies inventory management and integration into existing tooling setups.

FAQ

What materials is this insert recommended for?
The TNMG160408 T6215 insert is formulated for rostfreier Stahl and performs best under stable to lightly interrupted turning conditions.

How does the T6215 coating improve performance?
The T6215 CVD coating increases wear resistance and edge stability on the cemented carbide substrate, extending tool life during stainless-steel machining.

Is the insert compatible with standard TNMG holders?
Yes. The insert follows ISO dimensions for TNMG plates; compatibility depends on holder form, fastening and tolerance class and should be confirmed with the chosen holder.

What benefits does the 0.8 mm corner radius provide?
A 0.8 mm radius offers a compromise between edge strength and profile control, reducing the risk of edge chipping while producing robust part geometry.

Can the insert be used for interrupted cuts?
The grade is intended for stable to slightly interrupted conditions; heavily interrupted cuts may require a more robust geometry or different grade.
