CNMG 120404 T9225 Wendeplatten - Tungaloy

Reliable results and extended tool life derive from the combination of a CVD‑coated carbide (T9225) grade and a 0.4 mm corner radius, optimised for medium‑to‑heavy Stahl turning. The ISO rhombic geometry and 12 mm size ensure consistent seating and fast index changes. Order the CNMG120404 T9225 insert directly via Metav Werkzeuge or ask our consultants if needed.

CNMG120404 T9225 Tungaloy turning insert

CNMG120404 T9225 is a robust CVD‑coated carbide insert intended for medium to heavy turning applications, especially under varying engagement conditions

• CVD‑coated carbide for robust performance
• ISO rhombic CNMG 12 mm geometry
• Double‑sided chipbreaker, cylindrical hole
• 0.4 mm corner radius for versatile finishes

Consistent cutting performance for demanding turning

The CVD‑coated carbide grade T9225 offers a reliable balance between wear resistance and toughness, which is beneficial when facing changing cut conditions or light interruptions. The coating reduces flank wear and improves tool life, so single inserts maintain productive cutting over longer cycles. A double‑sided chipbreaker stabilises chip flow and supports higher metal removal rates while helping to protect the cutting edge during intermittent cuts, resulting in more predictable cycle times and fewer unplanned tool changes.

Secure seating and repeatable geometry reduce setup time

Specified to ISO dimensions with a rhombic CNMG profile, the insert features a 12 mm inscribed circle, 4.76 mm thickness and a cylindrical hole for secure clamping. The defined geometry and tolerance compatibility simplify holder selection since compatibility depends on form, clearance, tolerance class, fastening type, size and thickness. The nominal 0° clearance angle and the 80° included angle create stable contact conditions at the tool seat, improving repeatability between indexings and reducing manual adjustments during production runs.

Practical guidance for selecting and applying the grade

For turning operations in Stahl, this grade is suitable where a mix of toughness and wear resistance is required: select the T9225 grade and an appropriate chipbreaker depending on workpiece material and process stability. The small 0.4 mm corner radius balances edge strength with surface finish, making the insert versatile for both finishing and light roughing. Using standard ISO holders and the correct clamp set keeps changeover fast and secure; replacement screws and underlay packs complete a reliable system for series production. For less experienced users, specifying the insert by ISO designation and the Tungaloy grade ensures easier procurement and consistent results.

FAQ

What materials is this insert suitable for?
The CNMG120404 T9225 insert is designed primarily for Stahl machining, offering a balance of toughness and wear resistance for medium to heavy turning applications.

Can this insert handle interrupted cuts?
Yes. The T9225 grade and the double‑sided chipbreaker provide additional toughness and controlled chip formation, making the insert suitable for light interruptions.

Which holders are compatible with this geometry?
Compatibility depends on the ISO CNMG form, clearance, tolerance class, fastening method, size and thickness; selecting an ISO‑compatible external holder with matching seat dimensions ensures secure clamping.

Is the corner radius suitable for finishing work?
The 0.4 mm corner radius provides a compromise between edge strength and surface finish, allowing both finishing and light roughing with controlled tool life.

How does the coating affect tool life?
The CVD coating on the T9225 grade reduces flank wear and improves resistance to abrasive wear, which generally extends tool life compared with uncoated grades.
