TNMG 160404 T6215 Wendeplatten - Tungaloy

Take advantage of the combination of a CVD-coated carbide grade designed for stainless steel, a compact 60° geometry and a 0.4 mm corner radius to achieve stable, repeatable turning results with low wear; order directly via Metav Werkzeuge or ask their consultants for application-specific advice.

TNMG 160404 T6215 indexable turning insert — CVD-coated carbide, for turning

TNMG160404 T6215 is an ISO‑standard indexable turning insert engineered for external and internal turning of stainless steels under stable to mildly interrupted cutting conditions

• ISO triangular insert TNMG160404, 60° geometry
• CVD-coated carbide grade T6215 for stainless steel
• Double-sided chipbreaker, cylindrical hole
• 0.4 mm corner radius, 4.76 mm plate thickness

Consistent wear resistance for stainless‑steel machining

The insert uses a CVD-coated carbide substrate optimised as grade T6215, offering stable wear behaviour when turning stainless steel. This delivers a longer effective tool life under continuous production compared with uncoated grades, reducing changeover frequency and contributing to predictable process costs. The coating improves resistance to workpiece adhesion and abrasive wear, helping maintain cutting edge integrity and consistent dimensional results over extended runs.

Improved chip control and process stability

A double-sided chipbreaker combined with the 60° triangular form provides controlled chip formation and secure seating in compatible holders. The integrated cylindrical hole ensures repeatable clamping and quick indexation, while the 0.4 mm corner radius balances edge strength with acceptable surface finish. These design choices reduce vibration and help sustain stable cutting forces, which benefits throughput and surface quality when facing common challenges in turning stainless materials.

System compatibility and application guidance for reliable integration

As an ISO turning insert, compatibility with the clamping system depends on form, clearance angle, tolerance class, fastening method, size and thickness; the listed dimensions (16 mm size, 4.76 mm thickness) match many standard external holders and boring bars. Select the chipbreaker and grade according to workpiece material and machining stability: the T6215 variety is intended for stable to lightly interrupted operations on stainless grades. For less rigid set‑ups or heavy interruptions, consider a different chipformer or toolholding strategy to preserve edge life and process reliability.

FAQ

What materials is this insert intended for?
The TNMG160404 T6215 insert is specified for machining stainless steel under stable to slightly interrupted turning conditions.

How does the T6215 grade affect tool life?
The T6215 CVD coating improves wear resistance and reduces adhesion when turning stainless steels, resulting in more consistent edge life and fewer unscheduled indexings.

Is the insert compatible with standard ISO holders?
The insert follows ISO dimensions (TNMG160404); compatibility with a holder depends on form, clearance angle, tolerance class, fastening and size — the cylindrical hole and 60° geometry suit many standard holders.

Can the corner radius be changed?
This article is supplied with a 0.4 mm corner radius; for different radii, select the corresponding ISO designation or alternate indexable insert suited to the required surface finish and edge strength.

What are the benefits of a double‑sided chipbreaker?
A double‑sided chipbreaker extends usable edges per insert and offers a balance between chip control and cost efficiency for batch production and serial turning tasks.
