CNMG 120408 T9215 Turning insert (ISO 120408) by Tungaloy — CVD-coated carbide, 0° clearance

The CNMG120408 T9215 is an ISO-standard indexable turning insert designed for general external and internal turning in medium steels, optimised for continuous to slightly interrupted cuts.

• CVD-coated carbide grade T9215 for wear resistance
• ISO CNMG120408 geometry for secure holder fit
• Double-sided insert with a 0.8 mm corner radius
• Rhombic shape with cylindrical hole and 0° clearance angle

Consistent productivity through optimised grade and coating

The CVD-coated carbide T9215 grade combines high wear resistance with sufficient toughness to withstand light interruptions, which translates into longer tool life and fewer insert changes. In practice, this means stable cutting performance during medium-steel operations and reduced downtime. The CVD coating reduces flank wear and supports higher cutting speeds compared with uncoated grades; for users unfamiliar with coatings, CVD (chemical vapour deposition) applies a hard protective layer that improves abrasion resistance without compromising the insert’s core toughness.

Reliable geometry and easy holder compatibility

With the ISO CNMG120408 geometry and rhombic form, the insert matches common CNMG holders when form, clearance, tolerance class, fastening method, size and thickness are observed. The cylindrical hole and mounting dimensions follow ISO norms, so interoperability with standard external holders and boring bars is straightforward. The 0° clearance angle and 80° seating geometry deliver predictable chip formation and cutting forces, making tool set-up easier for production environments that require repeatable results.

Practical handling and application benefits on the shop floor

The double-sided design offers immediate cost efficiency: each insert provides two usable cutting edges before replacement, lowering per-edge cost. The 0.8 mm corner radius yields a good balance between edge strength and surface finish; a larger radius increases edge robustness, while a smaller radius improves detail and tolerance. For finishing passes, select appropriate feeds to avoid overloading the corner; for roughing, the same insert grade permits higher material removal rates thanks to its wear-resistant composition. The insert suits turning tasks where productivity and consistent quality are priorities.

FAQ

What materials is this insert suitable for?
The CNMG120408 T9215 insert is formulated for medium steel machining; the T9215 grade provides a combination of wear resistance and toughness suited to continuous and lightly interrupted turning operations.

How does the CVD coating affect tool life?
CVD-coated carbide on the CNMG120408 reduces abrasive wear and supports higher cutting speeds, which typically extends insert life and improves process stability in medium-steel applications.

Is this insert compatible with standard CNMG holders?
Yes — the CNMG120408 geometry is ISO-standard; compatibility depends on holder form, tolerance class, fastening method, size and thickness, so confirmation of holder specifications is recommended.

Can the insert be used for internal turning as well as external?
The rhombic CNMG120408 indexable insert is suitable for both external and internal turning when used with the appropriate external holder or boring bar designed for ISO CNMG inserts.

How many cutting edges does each insert provide?
This double-sided insert gives two usable cutting edges per side before indexing or replacement, improving cost-effectiveness in continuous production.
