CNMG 090408 T9215 Tungaloy indexable insert for turning, CVD-coated carbide

The CNMG090408 T9215 is an ISO-standard indexable turning insert engineered for productive external and internal turning of medium steels, offering a balance of wear resistance and breakage safety in continuous to lightly interrupted operations.

• CVD-coated carbide grade T9215
• ISO CNMG090408 rhombic geometry
• 0° clearance angle for stable cutting
• Double-sided chipbreaker, 0.8 mm radius

Increased throughput through a wear-resistant grade

The primary advantage of the T9215 grade is its combination of high wear resistance and fracture toughness, achieved by a CVD coating on a carbide substrate. This characteristic reduces the frequency of index changes and keeps cycle times low, which directly improves cost per part in series production. For operations that run continuously or with light interruptions, the material choice supports longer uninterrupted tool life and consistent dimensional stability, helping to maintain throughput targets and predictable maintenance intervals.

Precise geometry for consistent surface finish

The rhombic CNMG geometry with an 80° included angle, 0.8 mm corner radius and a 4.76 mm plate thickness provides a stable cutting edge and predictable engagement with the workpiece. The 0° clearance angle and the cylindrical locating hole ensure reproducible seating in compatible clamping systems. These design choices translate into improved surface quality and repeatable part tolerances, particularly when paired with the correct holder geometry and tolerance class. Technical terms: the corner radius affects edge strength and finish, while plate thickness contributes to rigidity in heavy feed conditions.

System compatibility and economical handling

As an ISO turning insert, the component is compatible with a wide range of external holders and boring bars when holder form, relief angle, tolerance class, fastening method, size and thickness match. The insert is double-sided with a dual chipbreaker, allowing indexing to a fresh cutting edge and halving the cost per usable edge versus single-sided variants. The cylindrical hole facilitates secure clamping; spare screws and proper underlay or clamp sets help ensure repeatable mounting without time-consuming adjustments. Selection of the correct chipbreaker style remains essential for chip control and process stability.

Practical benefits from grade and design choices

Choosing this Tungaloy grade and geometry supports a productive machining strategy: stable chip formation, reduced edge chipping risk and straightforward integration into common ISO tool systems. The CVD coating enhances thermal and abrasive resistance, while the substrate provides the necessary toughness for interrupted cuts. For workshops seeking predictable tool life and consistent results on medium steels, this insert offers a practical balance of performance and economy without complex handling or special coolant requirements.

FAQ

What materials is this insert best suited for?
The insert is optimised for medium-steel machining; the T9215 grade combines wear resistance and toughness for productive turning of steel.

Is the CNMG090408 compatible with standard ISO holders?
Yes, the CNMG090408 follows ISO geometry standards; compatibility depends on matching holder form, relief angle, tolerance class, fastening method, size and thickness.

How does the CVD coating improve performance?
The CVD coating on the carbide substrate increases thermal and abrasive resistance, extending edge life and supporting higher cutting volumes with stable chip formation.

Can the insert be indexed to a fresh edge?
The component is double-sided and permits indexing to an unused cutting edge, effectively doubling the number of usable edges compared with single-sided plates.

Which chipbreaker should be selected for mixed operations?
Choose the chipbreaker variant that matches the material, feed and stability requirements; the supplied double-sided chipbreaker offers flexibility for typical turning tasks.
