TPMT16T304‑PSS T6215 — ISO turning insert for stainless steel, 0.4 mm corner radius, Tungaloy

The TPMT16T304‑PSS T6215 is an ISO‑standard triangular turning insert intended for external and internal turning, engineered for machining stainless steels under stable to slightly interrupted cutting conditions.

• CVD‑coated carbide for high wear resistance
• Optimised for stainless steel turning
• Triangular 60° insert with 0.4 mm radius
• Central hole with 40°–60° countersink

Longer tool life through advanced coating and grade selection

The combination of a CVD‑coated surface and a wear‑resistant carbide substrate in the T6215 grade delivers extended tool life and stable cutting action when machining stainless steel. A durable coating reduces abrasive wear and thermal degradation on the cutting edges, which translates to fewer indexings and lower overall tooling costs in continuous production runs. The PSS chipbreaker aids in producing short, controllable chips on ductile materials, improving surface quality and lowering the risk of built‑up edge during medium‑feed operations.

Accurate geometry for secure clamping and predictable chip control

A triangular insert with a 60° geometry and 0.4 mm corner radius gives a reliable compromise between strength and profile definition. The insert features a central hole with a cylindrical bore and a single‑sided countersink (40°–60°) to ensure positive seating and repeatable positioning in compatible ISO holders; the compatibility depends on form, clearance, tolerance class, fixing method, size and thickness. The 11° clearance and a plate thickness of 3.97 mm provide sufficient rigidity for stable cuts while allowing easy fitting into standard toolholders. Such geometry ensures predictable chip formation and reduces vibration when the tool is used within recommended parameters.

Practical advantages and application guidance for production use

Designed for both external and internal turning, the insert performs best in stable to mildly interrupted cutting conditions where the PSS chipbreaker promotes manageable chips and consistent surface finish. Selection of the chipbreaker and grade should correspond to workpiece stability and feed rates: choose the PSS variant and T6215 grade for ductile, adhesive‑prone stainless alloys to limit built‑up edge and keep cycle times steady. Using this insert as part of a complete system—insert, appropriate holder, shim/underlay and correct clamping screw—helps achieve reproducible results, lower scrap rates and an efficient production flow.

FAQ

What materials is this insert suitable for?
The TPMT16T304‑PSS T6215 is specified for machining stainless steels and performs best under stable to slightly interrupted cutting conditions.

How does the PSS chipbreaker affect machining results?
The PSS chipbreaker promotes short, controlled chips on ductile materials, helping to avoid long stringy chips and improving surface finish during turning with the T6215 grade.

Which geometry and dimensions should be noted when selecting a holder?
Key dimensions are the 60° geometry, 0.4 mm corner radius and 3.97 mm thickness; the insert’s central hole with countersink requires a matching clamping system for correct seating.

Can this insert be used for internal turning as well as external turning?
Yes, the insert is designed for both external and internal turning applications when used in suitable ISO‑compatible holders.

What is the intended workpiece condition for best performance?
Best results with this grade and chipbreaker are achieved on stable to mildly interrupted cuts; severe interruptions or unstable setups will reduce performance and tool life.
