TNMG160408 T6215 — ISO triangular turning insert (Turning), CVD-coated carbide — Tungaloy

TNMG160408 T6215 is an ISO-standard triangular turning insert designed for stable external and internal turning operations, especially on stainless steels.

• TNMG160408 geometry for 60° turning
• CVD-coated carbide grade T6215 for stainless steels
• Double-sided insert with cylindrical hole
• 0° clearance for stable cutting conditions

Consistent wear resistance for stainless-steel turning

The CVD-coated T6215 grade combines a hard, wear-resistant surface with a tough carbide substrate to extend tool life during continuous and slightly interrupted cuts on stainless steels. The chemical vapour deposition process produces a uniform CVD coating that reduces adhesion and built-up edge, which is a common challenge when machining austenitic stainless grades. For production environments this means fewer insert changes and more predictable cycle times; the outcome is improved process stability and better overall economy per cutting edge. The insert grade is engineered for repeatable performance in series turning, where consistent surface quality and dimensional stability matter.

Geometry and edge form tuned for productive machining

The triangular form with an included angle of 60° and a 0.8 mm nose radius provides a balance between edge strength and surface finish. The neutral 0° clearance is suitable for stable setups and offers reliable contact behaviour in both external and internal turning. As a double-sided indexable insert with a cylindrical locating hole, it provides two usable cutting edges and straightforward seating in compatible ISO holders. Compatibility with a holder depends on form, clearance angle, tolerance class, fastening, size and thickness; using the correct clamping arrangement and matching the chipbreaker to the workpiece and machining conditions will deliver the best results in finishing and semi-finishing passes.

System approach, application advice and productivity gains

This insert is part of an ISO turning insert system and is intended for use with a matching external holder or boring bar, clamping set and replacement screws. The ISO series designation ensures interchangeability within standard tool systems when the holder geometry is matched correctly. For stainless-steel applications, chip control and coolant strategy influence tool life significantly; selecting the appropriate chipbreaker and optimising cutting parameters helps to avoid built-up edge and maintain surface integrity. In production-oriented shops the result is fewer interruptions, consistent surface quality and improved throughput — all supporting a productive machining process and reliable batch output.

FAQ

What materials is this insert intended for?
The TNMG160408 T6215 insert is designed primarily for stainless steels, offering wear-resistant performance under stable to lightly interrupted cutting conditions.

Which toolholders are compatible with this insert?
Compatibility requires matching form, clearance angle, tolerance class, fastening method, plate size and thickness; the TNMG160408 will fit standard ISO triangular turning holders when these parameters align.

How many cutting edges are available per insert?
The insert is double-sided; rotating the indexable plate provides two usable cutting edges before replacement is required.

What advantages does the T6215 CVD coating provide?
The CVD coating on grade T6215 increases wear resistance and reduces adhesion when machining stainless steels, improving edge life and ensuring more consistent surface finish.

Is the insert suitable for internal turning and finishing operations?
Yes, the TNMG160408 geometry and 0.8 mm nose radius make it suitable for both external and internal turning, with careful selection of chipbreaker and machining parameters for finishing passes.
