TNMG 160404 T6215 – Triangular turning insert (ISO) by Tungaloy

The TNMG 160404 T6215 is an ISO‑standard triangular turning insert engineered for external and internal turning of stainless steels under stable to slightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Optimised for stainless steel turning
• ISO TNMG 160404 triangular form
• Cylindrical hole with secure locating

Consistent machining performance for stainless components

The combination of CVD-coated carbide and the T6215 grade provides consistent tool life and predictable wear patterns when machining rostfreier Stahl. The 60° triangular geometry concentrates cutting forces efficiently, while the double-sided chipbreaker promotes controlled chip formation. As a result, processes run with improved stability and fewer unscheduled tool changes, which supports higher production throughput and lower overall machining costs.

Coating and substrate explained for reliable tool life

A CVD coating on a hardmetal substrate increases wear resistance and helps maintain a sharp cutting edge at elevated temperatures typical for stainless steel turning. This coating type resists abrasive wear and reduces built-up edge tendencies, making the insert suitable for continuous and slightly interrupted cuts. The combination of coating and substrate therefore translates into longer tool life and more consistent component quality.

ISO compatibility and secure clamping for workshop convenience

The insert follows ISO dimensions and is compatible with holders that match form, clearance, tolerance class, fastening method, size and thickness. The 0° clearance angle, cylindrical hole, and precise dimensions (inscribed circle 16 mm, thickness 4.76 mm) ensure secure seating and repeatable indexing. The standardisation simplifies inventory management: matching inserts, holders and clamping hardware form a clear system for fast replacement and minimal setup time.

Practical advantages for surface finish and strength

The 0.4 mm corner radius provides a compromise between edge strength and surface quality — suitable for finishing passes as well as more robust turning operations. The insert’s thickness of 4.76 mm contributes to rigidity, reducing vibration on longer overhangs and improving surface integrity. With its double-sided design, each insert offers two usable edges, supporting economical use in production environments where both consistency and availability matter.

FAQ

What materials is this insert suitable for?
The Tungaloy TNMG 160404 T6215 insert is designed primarily for rostfreier Stahl (stainless steel) and performs well under stable to slightly interrupted cutting conditions.

How does the T6215 grade affect machining?
The T6215 CVD-coated grade improves wear resistance and edge stability, which helps to maintain consistent cutting performance and extend tool life during stainless steel turning.

Is the TNMG 160404 compatible with standard ISO holders?
Yes, the insert uses ISO TNMG dimensions; compatibility depends on matching the holder’s form, clearance, tolerance class, fastening and thickness to the insert specifications.

What advantage does the 0.4 mm radius offer?
A 0.4 mm corner radius offers a balance between cutting-edge strength and surface finish, suitable for a variety of turning tasks from light finishing to more robust passes.

Can the insert be used for interrupted cuts?
The T6215 grade and insert geometry are suited to stable to slightly interrupted cuts; heavy interruptions may require a different tool grade or cutting strategy.
