CNMG090408 T9225 Tungaloy indexable insert — CVD‑coated carbide, 80° rhombic

The CNMG090408 T9225 is an ISO‑format indexable insert for turning, intended for robust external and internal turning where variable cutting conditions require a tougher, versatile grade.

• CVD‑coated carbide grade T9225
• 80° rhombic CNMG form for stable turning
• Double‑sided chipbreaker for reliable chips
• 0.8 mm corner radius for strength and finish

Process stability in changing conditions

The CVD‑coated carbide composition of this insert and the tough T9225 grade are engineered for medium to heavy steel machining and applications with light interruptions or variable engagement. The coating increases thermal stability and wear resistance, so machining cycles stay predictable across batch runs. This results in fewer tool changes and more consistent part quality, making the insert a practical choice where uptime and repeatable performance are priorities.

Predictable chip formation and improved surface quality

The combination of the double‑sided chipbreaker and the 80° rhombic geometry supports controlled chip evacuation and stable cutting forces. The 0.8 mm corner radius balances edge strength and surface finish, reducing vibration risk during heavier cuts while still allowing acceptable part appearance. For customers focused on efficient production, these features help to lower scrap rates and improve throughput on both external and internal turning operations.

Seamless integration into ISO turning systems

As an ISO‑format CNMG insert, compatibility with holders depends on form, relief angle, tolerance class, clamping method, size and thickness. The insert’s 4.76 mm plate thickness and rhombic shape are standard for many external holder and boring bar systems; the insert is supplied with a cylindrical hole for secure clamping. This standardised interface simplifies tool procurement and replacement in multi‑machine environments, aiding faster set‑ups and consistent tool behaviour across the shop floor.

Practical selection and application advice for productivity

Choose this insert when the process demands a robust, general‑purpose grade that tolerates slight interruptions or unstable cut entry. It is particularly suitable for stepped or roughing passes where a balance of toughness and wear resistance is required. For finishing passes, the same geometry can offer acceptable surface integrity when cutting parameters are adjusted. For tailored cutting data and optimisation, Metav Werkzeuge can advise on feed, speed and holder selection to maximise productivity while protecting tool life.

FAQ

Which materials is this insert intended for?
The CNMG090408 T9225 insert by Tungaloy is a robust universal grade designed primarily for medium to heavy steel machining and performs well when varying engagement or light interruptions require added toughness.

Can this insert be used for internal turning and boring operations?
Yes, the ISO CNMG format and rhombic geometry make the insert suitable for both external and internal turning; compatibility with a specific boring bar or holder must be checked by matching form, relief angle, tolerance and clamping method.

What does the T9225 grade indicate?
T9225 denotes a CVD‑coated carbide grade developed for a broad range of steel applications, combining thermal stability and toughness to deliver reliable tool life under mixed cutting conditions.

What are the key dimensions of the CNMG090408 insert?
The insert is ISO CNMG090408, size 09, with a plate thickness of 4.76 mm and a corner radius of 0.8 mm; it features an 80° included angle and a relief angle of 0°.

How is chip control achieved with this insert?
Chip control is managed by the double‑sided chipbreaker geometry and the rhombic form; together they promote predictable chip shapes and assist evacuation, which supports surface quality and tool life.
