TNMG 160412 T6215 — Tungaloy turning insert for stainless steel turning

The TNMG160412 T6215 is a 60° triangular indexable insert designed for turning applications, optimised for rostfreiem stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide T6215 grade
• Optimised for stainless steel turning
• Double-sided chipbreaker design
• 1.2 mm corner radius, 60° triangular

Consistent edge life for demanding turning tasks

The solid base of this insert is carbide with a CVD-coated surface in grade T6215, developed for wear resistance when machining stainless steels. The coating reduces abrasive wear and improves thermal stability, which translates into longer in‑service intervals and fewer indexings. As a result, cycle times remain consistent and tool-change frequency is reduced, supporting steady shop-floor throughput and measurable cost efficiency.

ISO compatibility and secure clamping for predictable fit

Produced to the ISO-standard TNMG geometry, the insert’s compatibility with a holder is determined by form, relief angle, tolerance class, fastening method, size and thickness. The insert has a 0° relief angle, a cylindrical hole and nominal plate dimensions of 16 mm with a thickness of 4.76 mm, fitting conventional external holders when the correct clamping set and screw are used. This standardisation simplifies inventory management and ensures straightforward replacement in established turning systems.

Process stability and economical performance

The double-sided chipbreaker provides consistent chip control on both indexable faces, improving surface finish and reducing the risk of built-up edge when cutting stainless steels. The 1.2 mm corner radius contributes to edge strength, enabling more robust machining passes without sacrificing dimensional control. Together, these characteristics reduce unexpected downtime and contribute to a favourable cost-per-part calculation, particularly in medium-volume production runs.

Practical selection and integration guidance

Selection of chipbreaker and grade should match the workpiece material, machining strategy and machine rigidity; the supplied T6215 grade is tailored to rostfreiem stainless steels under stable to slightly interrupted conditions. The insert forms part of a system: indexable insert, appropriate external holder or boring bar, underlay/clamping set and replacement screws. Correct matching of geometry and clamping delivers repeatable results and allows operators to exploit the insert’s full potential without complex setup changes.

FAQ

Which materials is this insert best suited for?
The TNMG160412 T6215 insert is optimised for stainless steels; the T6215 CVD-coated carbide grade provides improved wear resistance and edge stability for these alloys.

Is the insert compatible with standard ISO holders?
Yes; the TNMG160412 follows ISO geometry standards, but compatibility depends on matching form, relief angle, tolerance class, fastening, size and thickness with the chosen holder.

What effect does the 1.2 mm corner radius have on machining?
A 1.2 mm radius increases edge strength and vibration tolerance, making it suitable for more stable turning operations where a balance of finish and robustness is required.

How is the insert mounted in the holder?
The insert uses a cylindrical hole and is secured with the appropriate screw and clamping set; a correct underlay and tolerance‑matched holder ensure secure seating and repeatable positioning.

What advantages does the T6215 coating provide?
The T6215 CVD-coated carbide offers enhanced wear resistance and thermal stability when machining stainless steels, contributing to prolonged tool life and consistent surface quality.
