TPMT110308 T6215 – ISO turning insert, triangular, for turning (Tungaloy)

The TPMT110308-PS T6215 is an ISO-indexed triangular turning insert designed for external and internal turning of stainless steel under stable to slightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• For turning stainless steels
• Triangular ISO insert, 11° clearance angle
• 0.8 mm nose radius, 3.18 mm thickness

Durable cutting grade for consistent stainless-steel performance

The CVD-coated T6215 carbide grade provides enhanced wear resistance and thermal stability during prolonged cutting of stainless steel, making it suitable where consistent component quality and longer tool life are required. In typical production runs the combination of coating and carbide substrate reduces flank wear and maintains a stable cutting edge under steady cutting conditions, which translates into fewer interruptions for tool changes and a more predictable machining cycle.

Geometry engineered for compatibility and repeatable clamping

The insert’s triangular form and ISO geometry ensure straightforward integration with standard external holders and boring bars; compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness. The insert has an 11° clearance (relief) angle, a 0.8 mm nose radius and a plate thickness of 3.18 mm, plus a central cylindrical hole with a one-sided countersink (40°–60°) for secure fixing. These dimensions support accurate positioning and repeatable cutting performance across serial production.

Practical productivity benefits and chip control

Equipped with the PS chipbreaker, the insert promotes controlled chip formation when paired with appropriate feeds and speeds, reducing the risk of entanglement and improving surface finish. The indexable design allows multiple cutting edges per insert, lowering tooling costs per part. Use in a complete system — insert, compatible holder or bar, underlay/clamping set and replacement screw — supports faster tool changes and reduced downtime, contributing to a measurable improvement in process efficiency.

Application guidance and selection advice

Designed for turning operations, the insert performs in both external and internal turning tasks; select chipbreaker and grade according to workpiece material, rigidity of the setup and the type of cut (finishing vs. roughing). For slightly interrupted cuts or less rigid set-ups consider adjusting feed rates and selecting a holder that provides additional support. For tailored recommendations on holder compatibility and cutting data, Metav Werkzeuge’s technical advisers can help specify the correct combination for the intended application.

FAQ

What materials is this insert best suited for?
The TPMT110308-PS T6215 is optimised for stainless steel machining; the CVD-coated carbide grade T6215 provides wear resistance and thermal stability during turning operations.

What are the key dimensions and geometry of the insert?
This triangular ISO insert features a 0.8 mm nose radius, 3.18 mm thickness, 11° clearance angle and an included angle of 60°; it is supplied with a central cylindrical hole and a one-sided countersink (40°–60°).

How does compatibility with holders and bars work?
Compatibility is determined by the insert form, clearance angle, tolerance class, clamping method, size and thickness; the TPMT110308-PS requires a matching ISO triangular holder or boring bar for secure clamping.

Which chipbreaker should be used for typical turning tasks?
The PS chipbreaker fitted to this insert supports controlled chip formation in stable to slightly interrupted conditions; selecting the correct feed, speed and holder improves chip control and surface finish.

Is the insert indexable and how many edges are available?
The TPMT110308-PS T6215 is an indexable insert with multiple usable cutting edges provided by its triangular design and secure central clamping, allowing economical edge indexing during production.
