TNMG160402 T6215 Tungaloy turning insert — CVD-coated carbide, 0.2 mm nose radius

TNMG160402 T6215 Tungaloy turning insert is a triangular ISO indexable insert designed for external and internal turning, particularly suited to machining stainless steels under stable to slightly interrupted cutting conditions

• CVD-coated carbide grade T6215
• Triangular ISO insert, 16 mm size
• 0.2 mm nose radius for fine finishing
• Double-sided chipbreaker, cylindrical hole

Consistent wear resistance for uninterrupted production

The CVD-coated carbide composition in grade T6215 provides a durable cutting edge and high wear resistance, which translates into extended tool life and fewer indexings. For series production, this behaviour reduces changeover frequency and supports a steady machining rhythm. The substrate material is cemented carbide, optimised for high-temperature abrasion resistance, while the coating enhances oxidative and abrasive wear control, making the insert particularly effective when machining stainless steels in stable cut conditions.

Secure clamping and geometry for predictable results

The triangular geometry combined with a cylindrical hole and matching tolerance class ensures safe, repeatable clamping in compatible ISO holders. The double-sided chipbreaker layout provides two usable cutting edges per side, improving cost efficiency per indexation. With a nominal size of 16 mm and a plate thickness of 4.76 mm, the insert fits standard TNMG-compatible toolholders; compatibility is determined by form, clearance angle, tolerance grade, fastening type, size and thickness, so holders must be matched accordingly.

Surface finish and edge stability optimised for fine turning

A 0.2 mm nose radius is well suited to fine finishing operations where dimensional accuracy and surface integrity are priorities. The small radius limits cutting forces while maintaining edge strength for light to medium cuts. In combination with the T6215 coating, edge robustness is improved, reducing the risk of notch wear and enabling more consistent surface quality on parts where appearance or fit is critical.

Application guidance and economic rationale

The insert is intended for turning applications and performs best under stable to lightly interrupted cuts; selection of chipbreaker style and grade should match workpiece material, cutting strategy and machine rigidity. The design supports productive machining of turned components with a favourable balance of tool life and process reliability, making it a cost-effective choice where repeatability and reduced downtime are essential.

FAQ

What materials is this insert best suited for?
The TNMG160402 T6215 Tungaloy turning insert (SKU 6944830-Tungaloy) is optimised for machining stainless steels under stable to slightly interrupted cutting conditions; the CVD coating improves wear resistance during such applications.

Can this insert be used for external and internal turning?
Yes, the triangular geometry and cylindrical-hole mounting make the insert suitable for both external and internal turning operations when used with a compatible ISO toolholder.

How many cutting edges are available per insert?
The insert features a double-sided chipbreaker design, providing multiple usable cutting edges to enhance economy per index and reduce tooling costs.

What surface finish can be expected with a 0.2 mm nose radius?
A 0.2 mm nose radius is intended for fine finishing, delivering good surface integrity and dimensional control while keeping cutting forces moderate on suitable setups.

Is the grade T6215 suitable for interrupted cuts?
Grade T6215 is designed for wear resistance and edge stability; it performs reliably in stable to lightly interrupted cuts, while heavy interruptions may require a more robust grade or adapted cutting parameters.
