TNMG 160404 T9225 turning insert (ISO) — Tungaloy, CVD-coated carbide, 0.4 mm radius

The TNMG160404 T9225 is an ISO-standard indexable turning insert designed for external and internal turning applications, offering a robust universal grade for changing engagement conditions and lightly interrupted cuts.

• CVD-coated carbide for extended tool life
• Robust universal grade T9225 for steel machining
• Triangular 16 mm insert, 60° geometry
• 0.4 mm nose radius, double-sided chipbreaker

Consistent performance for medium to heavy steel turning

The combination of a CVD coating and carbide substrate delivers improved wear resistance and a reliable cutting edge under variable cutting conditions. The T9225 grade is formulated as a robust universal option for steel machining, providing a balance of toughness and wear resistance that suits interrupted cuts or situations with fluctuating engagement. This results in fewer indexings and a steadier production rhythm, supporting predictable cycle times and reduced downtime.

ISO compatibility simplifies toolset management

As an ISO-standard insert, the geometry and dimensions follow established norms, so compatibility with external holders and boring bars is determined by insert form, clearance angle, tolerance class, fastening and thickness. The insert’s triangular shape and cylindrical hole allow straightforward seating in common ISO clamping systems. In practice, a complete system typically consists of the indexable insert, a suitable external holder or boring bar, a backing shim/clamp set and spare fixing screws for quick replacement and consistent clamping force.

Geometry and chip control for surface quality and economy

The 0.4 mm nose radius and 60° included angle yield a controlled contact zone that helps maintain surface finish while allowing higher feed options when appropriate. The double-sided chipbreaker design increases usable edges per insert and improves stable chip formation, reducing the risk of inconsistent chips that can harm surface quality or necessitate manual chip control. Thicker inserts and stable clamping contribute to vibration resistance, which in turn supports repeatable part quality.

Practical benefits: fewer tool changes, predictable uptime

Using a double-sided, triangular indexable insert reduces tooling costs per edge and simplifies inventory by favouring a versatile shape across multiple operations. The CVD-coated carbide surface enhances flank wear resistance on steels, extending edge life and improving the cost-per-component ratio. For shop-floor planning, this insert supports efficient tool change routines and steady output, making it suitable for both batch production and continuous turning tasks.
