TNMG 160412 T6215 – Tungaloy turning insert for stainless steel machining

The TNMG160412 T6215 is an ISO-standard triangular indexable insert for external and internal turning, designed for stable to lightly interrupted stainless steel applications.

• CVD-coated carbide grade T6215
• ISO triangular insert, 60° geometry
• Double-sided insert with cylindrical hole
• Optimised for stainless steel turning

Improve machining stability and extend cutting life

The combination of a CVD-coated surface and a hard carbide substrate provides elevated wear resistance and thermal stability, resulting in extended tool life under repetitive turning cycles. The T6215 grade is formulated for machining stainless steel where work-hardening and heat generation demand reliable wear control. The double-sided chipbreaker improves chip formation and evacuation, which reduces the risk of built-up edge and contributes to steady cutting forces and fewer unplanned tool changes.

Reliable fit, simple indexing and secure clamping

Designed to the ISO specification, the insert offers predictable seating and repeatable geometry when paired with a matching external holder or boring bar. The cylindrical hole aids accurate locating and clamping, while the insert dimensions — 16 mm size and 4.76 mm thickness — ensure compatibility with standard ISO triangular pockets. The neutral 0° relief angle and the defined tolerance class mean straightforward indexing and minimal set-up time, supporting faster tool changes and consistent part quality.

Achieve consistent surface finish in stainless steel turning

The 60° triangle geometry and a 1.2 mm corner radius deliver a balance between strength and edge radii for improved surface quality on shafts and bores. The engineered chip control fosters uniform chips, which reduces scratching and rework on the workpiece. For turning operations where process stability matters, the correct pairing of chipbreaker and grade produces reliable chip control and predictable surface results, even when cutting parameters vary slightly.

Economical productivity with predictable results

Using a wear-resistant insert like the one from Tungaloy helps lower overall machining costs through extended edge life and fewer changeovers. The indexable format and standardised form reduce inventory complexity, while the T6215 coating concept supports high process reliability in demanding stainless steel environments. The result is improved uptime and more consistent cycle times — attributes that translate directly into higher productivity on the shop floor.

FAQ

Which materials is this insert intended for?
The TNMG160412 T6215 insert from Tungaloy is optimised for machining stainless steel under stable to lightly interrupted conditions and can be selected where good wear resistance is required.

Is the insert indexable and reversible?
Yes, the insert is double-sided and indexable; both cutting edges can be rotated into position to extend usable life before replacement.

How is compatibility with toolholders ensured?
Compatibility is governed by the ISO form, the relief angle (0°), tolerance class, fastening method, size and thickness; the TNMG160412 designation confirms conformance to ISO triangular insert standards.

What benefits does the CVD coating provide?
The CVD coating on the T6215 grade increases surface hardness and thermal resilience, improving wear resistance and supporting consistent chip formation during stainless steel turning.

Is this insert suitable for heavily interrupted cuts?
The TNMG160412 T6215 is designed for stable to lightly interrupted applications; heavily interrupted cutting may require a geometry and grade specifically designed for shock resistance.
