TPMT 16T304 T9225 — Indexable turning insert (TPMT16T304-PSS) by Tungaloy, 60° triangle, 0.4 mm corner radius

TPMT16T304-PSS T9225 is a CVD-coated carbide indexable insert designed for medium to heavy turning applications, offering reliable edge stability and adaptable chip control for variable engagement conditions.

• CVD-coated carbide grade T9225
• Robust chip control with PSS breaker
• ISO 16T304 triangular geometry
• 0.4 mm corner radius for finishing

Consistent performance for medium to heavy steel turning

The TPMT16T304-PSS T9225 combines a CVD-coated carbide substrate with a universal wear-resistant grade to deliver consistent tool life in mixed production environments. The coating provides thermal resistance and improved flank wear behaviour, while the substrate maintains toughness during interrupted cuts. For operations where stability varies between finishes and heavier cuts, this insert reduces the frequency of tool changes and contributes to stable machining cycles, supporting predictable productivity.

Improved chip control and surface quality

Equipped with the PSS chipbreaker, the insert achieves controlled chip formation and evacuation, which leads to fewer tool interruptions and more consistent surface results. The 60° triangular geometry concentrates cutting forces and offers three effective cutting edges per indexable insert, optimising economy and setup time. By matching chipbreaker style and grade to the workpiece material and rigidity, shops benefit from reduced secondary operations and a smoother production flow.

Straightforward integration with ISO holders for reliable clamping

The ISO designation 16T304 signals broad compatibility with standard triangular turning holders when form, 11° relief angle, tolerance class, fastening method, size and thickness align. The insert’s cylindrical hole + single-side countersink (40°–60°) enables secure seating with common clamping systems, and the 3.97 mm thickness contributes to bending resistance under heavier feed conditions. This predictable fitment simplifies tool inventory and reduces the need for bespoke holder solutions.

Application flexibility and workshop advantages

Designed primarily for external and internal turning, the insert suits varied batch sizes and mixed-material workflows where a balance of wear resistance and toughness is required. The 0.4 mm corner radius is effective for light finishing and semi-finishing passes, offering a compromise between edge strength and surface finesse. Choosing the correct chipbreaker and stabilising the setup improves component consistency and cuts overall machining time, making the insert a practical choice for shops aiming to maintain throughput without sacrificing part quality.

FAQ

What materials is this insert best suited for?
The TPMT16T304-PSS T9225 insert is intended as a robust universal grade for medium to heavy steel machining, offering a balance of wear resistance and toughness for variable cutting conditions.

What are the key geometric features of the insert?
The insert features a 60° triangular geometry, a 0.4 mm corner radius, 3.97 mm thickness and an 11° relief angle, providing three usable cutting edges and reliable edge strength for finishing passes.

Which chipbreaker is fitted and what does it deliver?
The PSS chipbreaker is integrated on this insert to ensure controlled chip formation and improved evacuation, which supports longer uninterrupted cuts and more consistent surface finishes.

Is this insert compatible with standard holders?
Yes. The ISO designation 16T304 indicates compatibility with ISO triangular turning holders, subject to matching form, tolerance class, fastening and size requirements; the insert sits via a cylindrical hole + single-side countersink (40°–60°) for secure clamping.

How should the TPMT16T304-PSS T9225 be used in mixed-batch production?
Select the PSS chipbreaker and the T9225 grade where interrupted cuts or variable engagement occur; the insert’s universality reduces inventory complexity while maintaining process stability across diverse components.
