CNMG 120408 T9225 turning insert — CVD-coated carbide, 80° rhombic, by Tungaloy

The CNMG120408 T9225 Tungaloy turning insert is an ISO-standard indexable insert for external and internal turning, designed for robust performance where varied engagement conditions and interrupted cuts demand increased toughness.

• CVD-coated carbide grade T9225
• ISO CNMG120408 rhombic insert, 80° geometry
• Double-sided chipbreaker with cylindrical hole

Consistent productivity through robust grade and coating

The insert's CVD-coated carbide composition (grade T9225) provides a balance of hardness and toughness appropriate for medium to heavy steel machining. This combination reduces wear rates under fluctuating load and enables longer intervals between tool changes, which improves spindle uptime and lowers overall machining cost per component. The coating enhances resistance to adhesive and abrasive wear, while the substrate maintains edge stability when cuts are slightly interrupted. Such a setup is particularly suitable where consistent part quality and repeatability are required.

Predictable fit and repeatable accuracy across ISO systems

Manufactured to the ISO CNMG120408 designation, the insert offers straightforward interchangeability with compatible holders. The 80° rhombic geometry, 0° relief angle and defined thickness (4.76 mm) mean that form, clearance angle, tolerance class, fastening style and plate size determine compatibility. This standardisation simplifies tool planning and inventory management in a workshop equipped with CNMG toolholders, ensuring predictable cutting position and surface finish without the need for trial-and-error adjustments.

Improved chip control and secure clamping for shop-floor reliability

The double-sided chipbreaker promotes controlled chip formation across varying depths of cut, aiding evacuation and reducing the risk of chip entanglement on both external and internal turning tasks. The insert's cylindrical hole allows secure clamping on standard CNMG-style seats and provides stable mounting under moderate to heavy cutting forces. The corner radius 0.8 mm contributes to a robust cutting edge that balances finish and strength; the small radius supports fine detail work while still resisting edge chipping in interrupted cuts. Selecting the correct chipbreaker and grade according to workpiece stability and feed rates will maximise both performance and economy.

FAQ

What materials is this insert intended for? The CNMG120408 T9225 insert from Tungaloy is designed primarily for medium to heavy steel machining and performs well where changing engagement or light interruptions require added toughness.

Is the insert single- or double-sided? This indexable insert is double-sided with a chipbreaker on both faces; the Tungaloy CNMG120408 T9225 design allows turning and then indexed reversal to use the second cutting edge.

Which dimensions and geometry define this insert? Key dimensions are ISO CNMG120408 with an 80° rhombic geometry, plate size 12 mm, thickness 4.76 mm and a corner radius of 0.8 mm; the relief angle is 0°.

How is the insert secured in the holder? The insert features a cylindrical hole for standard CNMG clamping systems; compatibility depends on holder form, tolerance class, fastening method, size and thickness as described in the technical data.

What chip control and surface finish can be expected? The double-sided chipbreaker of the CNMG120408 T9225 promotes controlled chip formation and evacuation, aiding consistent surface finish while reducing the likelihood of chip-related interruptions.
