TPMT16T304-PS 16T304 T9215 — ISO turning insert (Tungaloy)

TPMT16T304-PS T9215 is an ISO-compliant triangular indexable insert designed for external and internal turning, optimised for medium-steel applications

• CVD-coated cemented carbide T9215
• Optimised for medium steel machining
• ISO triangular insert with cylindrical hole
• High wear resistance and fracture toughness

Consistent cutting performance for medium-steel turning

The triangular indexable insert delivers reliable tool life through a CVD-coated cemented carbide substrate identified as T9215. Chemical vapour deposition (CVD) applies a hard, wear-resistant layer that reduces flank and crater wear under continuous to slightly interrupted cutting. This composition combines wear resistance with fracture toughness, which supports stable, productive machining cycles and helps maintain component tolerances and surface quality during series production.

ISO compatibility simplifies tooling choices and inventory

As an ISO-standard insert, the part integrates into common turning systems; compatibility depends on form, relief angle, tolerance class, fastening, size and thickness. The system typically comprises the indexable insert, a matching external holder or boring bar, a supporting shim and clamp set, plus replacement fixing screws. Using standardised inserts streamlines stock management, reduces machine downtime and ensures predictable repeatability when assemblies are swapped between toolposts.

Geometry and chip control tuned to practical turning tasks

The insert features a 60° included angle and a 0.4 mm nose radius that balance edge strength and surface finish. A 11° relief angle supports general turning operations while the PS chipbreaker is suited to stable chip formation on medium steels. The plate thickness of 3.97 mm and a cylindrical hole with a one-sided countersink (40°–60°) enable secure clamping and consistent seat location, which is particularly important when repeatability and positional accuracy are required in production environments.

Application advice and operational benefits

Intended as a first-choice grade for medium-steel machining, this insert is suitable for both external and internal turning where continuous or lightly interrupted cuts occur. Selecting the correct chipbreaker and grade for the workpiece material and machining stability maximises tool life and productivity. The insert’s combination of geometry and T9215 grade aims to reduce unplanned tool changes, improve uptime and deliver consistent component surfaces without demanding specialised process parameters.

FAQ

Is this insert suitable for internal boring as well as external turning?
The TPMT16T304-PS T9215 insert by Tungaloy is designed for both external and internal turning tasks, provided the chosen holder or boring bar matches the insert’s form, size and clamping requirements.

What advantages does the T9215 grade offer for steel machining?
Tungaloy’s T9215 combines a CVD-coated cemented carbide structure with good wear resistance and fracture toughness, optimising tool life and process stability when machining medium steels.

How does the 0.4 mm nose radius affect surface finish and strength?
A 0.4 mm nose radius offers a compromise between improved surface finish and sufficient cutting-edge strength, making it suitable for many general turning operations without excessive tool load.

What does the PS chipbreaker mean in practice?
The PS chipbreaker is configured for controlled chip formation on medium steels, promoting stable chips under continuous to light interrupted cutting conditions and aiding swarf evacuation.

How should compatibility with toolholders be checked?
Compatibility depends on the insert’s shape, relief angle, fastening method, tolerance class, size and thickness; ensure the holder accepts 16T304 ISO triangular inserts and secures the cylindrical hole and countersink as specified.
