CNMG 120404 T9205 turning insert (ISO) by Tungaloy — CVD-coated carbide, 0° relief

The CNMG 120404 T9205 is an ISO-standard rhombic turning insert engineered for productive external and internal turning of steel, combining a wear-resistant CVD coating with a stable chipbreaker for consistent surface quality.

• CVD-coated carbide grade T9205
• Double-sided chipbreaker for stability
• ISO CNMG 120404, 80° rhombic form
• 0° relief for secure clamping

Increased productivity through wear-resistant coating

The CVD-coated carbide grade T9205 delivers high wear resistance and thermal stability, which permits higher cutting speeds under stable set-ups. This hard-wearing coating reduces flank wear and extends cutting edge life, so fewer indexings and insert changes are required during batch production. The result is a measurable improvement in machining throughput and lower overall tooling costs when machining steel.

Stable chip control and consistent surface finish

The double-sided chipbreaker and a corner radius of 0.4 mm provide controlled chip formation for turning operations where stability is present and predictable. The 80° rhombic form contributes to cutting edge strength and versatility between external and internal turning, while the 0° relief aids secure clamping in ISO holders. Together these features support repeatable surface quality and reduce the risk of vibration-related defects.

Seamless integration into ISO tool systems

As an ISO-standard insert in the CNMG family, compatibility with holders depends on form, relief angle, tolerance class, fastening and thickness; the plate size is 12 mm with a thickness of 4.76 mm and a cylindrical centre hole for clamping. Typical system assembly includes a matching external holder or boring bar, a shim/backup piece and replacement screws. Technical advisers can assist in matching the correct chipbreaker and grade to the specific material, operation and machine stability for optimum results.

FAQ

What materials is this insert designed for?
The Tungaloy CNMG 120404 T9205 insert is optimised for productive turning of steel and performs best under stable machining conditions where its CVD-coated carbides deliver high wear resistance.

How does the chipbreaker affect performance?
The double-sided chipbreaker on this insert provides controlled chip formation and improved stability, which helps to maintain consistent surface finish and extend tool life when the correct breaker is chosen for the material and cutting conditions.

Is the CNMG120404 compatible with standard holders?
Compatibility is determined by the insert form, relief angle, tolerance class, fastening method, size and thickness; the CNMG120404 conforms to ISO standards and fits ISO CNMG holders when those parameters match.

What are the key dimensional specifications to check before fitting?
Important dimensions include the 12 mm inscribed circle, 4.76 mm thickness, 0.4 mm corner radius and the 80° rhombic form; the centre hole is cylindrical for secure clamping.

Can this insert be used for internal as well as external turning?
Yes, the rhombic 80° geometry and robust cutting edge make the insert suitable for both external and internal turning operations, provided the holder and setup ensure sufficient stability.
