Benefit from the combination of a CVD-coated carbide grade for wear resistance, a 0.4 mm corner radius for robust cuts and ISO compatibility that simplifies holder selection — order the insert directly via Metav Werkzeuge or ask our consultants for application advice.

CNMG 090404 T9225 ISO turning insert by Tungaloy — rhombic indexable insert for turning

The CNMG 090404 T9225 is an ISO-standard rhombic indexable insert designed for external and internal turning in medium to heavy steel machining.

• CVD-coated carbide grade T9225
• Rhombic CNMG 09 insert, 80° geometry
• Double-sided chipbreaker, with cylindrical hole
• 0.4 mm corner radius for robust cuts

Predictable tool life through robust CVD-coated carbide

The CVD-coated carbide T9225 offers a balanced combination of abrasion resistance and toughness, making this grade well suited to variable engagement and slightly interrupted cuts. The controlled coating structure reduces flank wear and enhances edge stability under mid-to-heavy cutting conditions, which leads to more consistent tool life and fewer unexpected tool changes. For operations where process predictability is essential, the coated substrate contributes directly to steadier cycle times and reduced rework.

Stable clamping and effective chip control for safer machining

The rhombic CNMG geometry with an 80° included angle and a double-sided chipbreaker supports secure seating in standard ISO holders and promotes repeatable chip formation. The insert’s cylindrical hole and standardised dimensions ensure compatibility is governed by form, clearance angle, tolerance class, fixation method, size and thickness — factors that determine a reliable clamp and minimise vibration. Improved chip control reduces the risk of built-up edge and aids evacuation, which in turn supports surface quality and operator safety.

Versatile performance across turning tasks with high rigidity

With a nominal thickness of 4.76 mm and a 0.4 mm corner radius, this insert delivers the rigidity needed for stable turning and moderate finishing work. The neutral clearance angle (0°) and the CNMG seat geometry make the insert adaptable to both external and internal turning duties, while the universal character of the grade supports a wide range of steels. Using a single standardised insert across several workpieces simplifies tool inventory and reduces setup complexity without sacrificing machining strength.

Simple system integration and economical indexing

As an ISO-series indexable plate, the insert fits into a system comprising a matching external holder or boring bar, a support shim/clamping set and replacement screws. The double-sided design enables two usable edges per index, improving cost-efficiency per edge compared with single-sided alternatives. For workshop managers looking to streamline procurement and ensure quick replacement cycles, the standard dimensions and proven grade help to reduce downtime and support predictable production planning.

FAQ

What materials is this insert best suited for?
The CNMG 090404 T9225 insert is optimised for medium to heavy steel machining; the CVD-coated carbide grade T9225 provides a good balance of wear resistance and toughness for variable cutting conditions.

Can this insert be used in interrupted cuts?
Yes, the robust grade and the 0.4 mm corner radius make the insert suitable for slightly interrupted cuts and changing engagement conditions common in turning operations.

How does the double-sided chipbreaker benefit production?
The double-sided chipbreaker promotes consistent chip formation and allows indexing to a fresh edge, improving edge life and reducing the frequency of tool changes for the indexable turning plate.
