TPMT 16T304 T9215 — ISO turning indexable insert, CVD‑coated carbide, 0.4 mm corner radius — Tungaloy

TPMT 16T304 T9215 is an ISO‑standard triangular indexable insert designed for external and internal turning in medium steel machining, combining robust wear resistance with stable chip control.

• TPMT indexable insert, ISO 16T304
• CVD‑coated carbide grade T9215
• Triangular shape with 0.4 mm corner radius
• 11° relief angle, cylindrical hole + countersink

Productive performance for medium steel turning

The insert’s CVD‑coated carbide grade T9215 provides a balanced combination of wear resistance and fracture toughness, making it particularly suitable for medium steel applications and continuous to lightly interrupted cuts. The integrated chipbreaker TSF promotes controlled chip formation and evacuation which supports higher feed rates and stable machining. These characteristics translate directly into improved throughput and predictable tool life, delivering a rational, performance‑driven advantage on the shop floor.

Secure clamping and ISO compatibility for consistent results

Manufactured to the ISO series specification, the insert is compatible with matching holders when form, relief angle, tolerance class, fastening method, size and thickness align. The part features a cylindrical hole with a single‑sided countersink (40°–60°) which assists accurate seating and repeatable clamping torque in standard toolholders and boring bars. This design focus reduces setup variability and contributes to more consistent component quality in batch production.

Geometry engineered for precision and surface finish

The triangular geometry with a 60° included angle and 0.4 mm corner radius offers a compromise between robustness and finishing capability: the small radius supports good surface integrity on external profiles while resisting edge chipping in general turning tasks. A 11° relief angle and a plate thickness of 3.97 mm ensure stable cutting edge support under radial and axial loads. These dimensional details are intended to produce repeatable surface finishes and dimensional control without sacrificing productivity.

Practical application guidance and selection tips

Intended for turning operations, the insert performs best when paired with an appropriate holder and cutting data matched to the workpiece and operation type. Select the TSF chipbreaker and T9215 grade for steel workpieces to maximise process reliability and tool life. For shorter runs or when encountering interrupted cuts, favour modest feeds and monitor edge condition; for continuous turning, advance cutting parameters gradually while keeping coolant and machine rigidity in mind. For further specification or optimisation of cutting parameters, Metav Werkzeuge’s consultants are available to advise on exact holder matching and parameter tuning.

FAQ

Which materials are best machined with this insert? The T9215 CVD‑coated grade is optimised for medium steel machining; the TPMT16T304‑TSF insert delivers wear resistance and fracture toughness suited to continuous and light interrupted cuts in steel.

How is holder compatibility ensured for these ISO inserts? Compatibility depends on the holder’s form, relief angle, tolerance class, fastening method, size and thickness; the TPMT format and the insert’s hole/countersink geometry enable secure seating in matching ISO toolholders.

What benefit does the TSF chipbreaker provide? The chipbreaker TSF improves chip control and evacuation during turning, which supports higher feeds and more stable cutting, reducing the risk of rework and improving productivity with the T9215 grade insert.

Can this insert be used for internal turning operations? Yes; the triangular TPMT geometry and standard hole arrangement allow use in appropriate boring bars and internal turning holders for both external and internal turning tasks.
