TPMT16T308-PS T9225 – ISO triangular turning insert, CVD-coated carbide, PS chipbreaker by Tungaloy

The TPMT16T308-PS T9225 is an ISO‑standard triangular turning insert intended for external and internal turning, offering a universal, tough grade for interrupted cuts and varying engagement conditions.

• CVD-coated carbide for high wear resistance
• Robust universal grade T9225
• PS chipbreaker for controlled chip formation
• Triangular ISO form with 11° clearance

Consistent performance for mixed and interrupted turning

The triangular indexable insert delivers stable cutting behaviour in applications where engagement varies. The CVD‑coated carbide composition of the grade provides a balanced combination of hardness and toughness, which reduces flank and crater wear over extended runs. The PS chipbreaker is optimised for reliable chip segmentation during medium to heavy steel turning, lowering the risk of chip entanglement and improving surface finish consistency. These technical attributes translate directly into fewer tool changes and more predictable cycle times on production lines.

Clear mounting compatibility and secure clamping

Compatibility with toolholders is defined by form, clearance angle, tolerance class, mounting method, size and thickness. The insert’s triangular shape and centred hole with a single‑side countersink enable secure clamping in standard ISO holders and boring bars, improving repeatability when re‑indexing. The 11° clearance and 60° included angle ensure a stable cutting edge engagement, while the 0.8 mm corner radius helps to distribute cutting forces on heavier depths of cut. Specifying the correct holder geometry ensures the mechanical interface is matched and vibration is minimised.

Productivity, economy and material range

Designed as a robust universal grade, the T9225 lot balances tool life and process security; for many steel turning operations this balance reduces total cost per component by extending insert life without sacrificing finish. The 3.97 mm thickness and 16 mm size support a range of clamping options and allow predictable cutting parameters across batch and bespoke work. When paired with an appropriate toolholder and cutting data, the insert contributes to improved throughput and reproducible results, particularly where intermittent cuts demand additional toughness.

FAQ

What steels is this insert suitable for?
The TPMT16T308-PS T9225 from Tungaloy is formulated for medium to heavy steel turning and performs well under slightly interrupted cuts where added toughness is required; specify the grade T9225 when ordering (SKU TUN6781158).

How does the PS chipbreaker affect machining?
The PS chipbreaker on this CVD‑coated carbide insert promotes controlled chip formation and evacuation, which reduces rework and improves surface finish during continuous and interrupted turning operations.

Which toolholders are compatible with this insert?
Compatibility depends on form, clearance angle, tolerance and size; the triangular ISO form and centred hole allow mounting in standard ISO triangular holders and suitable boring bars when the 11° clearance is respected.

Can this insert be used for internal turning?
Yes, the insert is suitable for both external and internal turning when paired with an appropriate holder and cutting data; assess holder rigidity for internal operations to maintain stability.
