TNMG 160408 T9225 — Indexable turning insert, CVD‑coated carbide, for Turning — Tungaloy

The TNMG160408 T9225 is an ISO‑standard triangular indexable insert for external and internal turning, developed for medium‑to‑heavy steel machining where toughness and reliable chip control are required.

• CVD-coated carbide grade T9225
• Robust universal grade for steel machining
• Double-sided chipbreaker for stable cuts
• ISO TNMG triangular 60° form

Reliable performance for medium‑to‑heavy steel turning

The combination of a CVD‑coated surface on a carbide substrate and the T9225 grade delivers a balance of wear resistance and toughness suited to variable cutting conditions. This makes the insert especially efficient for interrupted cuts or applications with changing engagement. The engineered coating reduces flank wear and extends the interval between indexings, which improves productivity and lowers machining cost per part. The design supports consistent dimensional results across batch production and one‑off jobs alike.

Improved chip control and process stability under load

A double‑sided chipbreaker on the triangular insert promotes predictable chip formation and evacuation, reducing the risk of built‑up edge and tool vibration during heavier feeds. The 60° triangular geometry, paired with a 0° clearance angle, provides positive engagement for robust turning while maintaining cutting edge stability. The through‑hole with a cylindrical bore secures axial clamping and helps maintain repeatable seating on compatible holders, contributing to stable cutting forces and better surface finish.

Optimised compatibility and economical tool management

Conforming to ISO TNMG dimensions simplifies tool selection and inventory: 16 mm inscribed circle, 4.76 mm thickness, and a 0.8 mm corner radius are consistent with widely used holders and clamping systems. The insert is double‑edged, allowing economical re‑indexing and rapid replacement, which reduces downtime. Selection of the matching outer holder and correct clamping torque is essential to exploit the insert’s performance; when combined with a suitable holder and the correct feed/speed strategy, the result is reliable productivity and reproducible part quality.

FAQ

What materials is this insert optimised for?
The Tungaloy TNMG160408 T9225 insert is optimised for medium‑to‑heavy steel machining and performs well where toughness and reliable chip control are required.

How does the T9225 grade affect tool life?
The T9225 grade combines a CVD coating with a tough carbide substrate to deliver improved wear resistance and enhanced edge stability, which typically extends the time between indexing operations.

Is the insert compatible with standard ISO TNMG holders?
Yes, the insert follows the ISO TNMG160408 form and is compatible with holders designed for TNMG inserts, provided the holder matches form, clearance, tolerance and clamping specifications.

What does the 0.8 mm radius mean for cutting performance?
A 0.8 mm radius helps absorb cutting forces and improves edge strength versus a sharper corner, offering better stability for heavier cuts and intermittent machining.

How is the insert secured in the holder?
The insert features a cylindrical through‑hole for secure axial clamping; correct seating and clamping torque on a compatible holder are essential for repeatable performance.
