CNMG120412 T9225 — ISO turning insert for medium to heavy steel, Tungaloy

CNMG120412 T9225 Tungaloy-Wendeplatte is an ISO‑standard turning insert suited to external and internal turning where changing engagement conditions or light interruptions demand higher toughness.

• CVD-coated carbide for robust wear resistance
• Universal grade T9225 for medium to heavy steel
• ISO CNMG120412 shape for broad compatibility
• Double-sided chipbreaker with central cylindrical hole

Productive turning with a universal, tough grade

The insert is delivered in the T9225 grade, a CVD‑coated carbide designed as a universal solution for medium to heavy steel machining. This composition balances hardness and toughness so that stability in the cut is maintained even when engagement varies or slight interruptions occur; the result is longer tool life and fewer indexings. The coated surface increases thermal resistance and reduces adhesion, which helps to avoid built‑up edge formation and maintain consistent surface finish when turning steel.

Precision geometry that fits standard systems

As an ISO CNMG120412 insert, the geometry follows international standards and therefore integrates easily with compatible external holders and boring bars. The rhombic shape and 80° approach angle provide good access for both external and internal turning, while the 1.2 mm corner radius supports stable cutting at moderate feeds. Important interface parameters such as form, clearance angle (0°), tolerance class, fastening and plate thickness (4.76 mm) determine correct holder selection; matching these values ensures secure clamping and repeatable cutting performance.

Operational benefits for everyday workshop demands

The double‑sided chipbreaker and the central cylindrical hole enable reliable indexing and economical use of both cutting edges. For workshop workflows this translates into fewer tool changes and predictable process times when machining steel components. The insert suits typical turning tasks — roughing and semi‑finishing — where process reliability and consistent surface quality matter. The CVD coating contributes to improved edge life under thermal load, while the substrate composition maintains a robust cutting edge for interrupted cuts.

FAQ

Which materials is this insert best suited for?
The CNMG120412 T9225 Tungaloy insert is optimised for steel machining, particularly medium to heavy grades, and performs well under slightly interrupted cuts thanks to its toughness and CVD coating.

What holder specifications are required for this insert?
Holders must accept an ISO CNMG insert with a 12 mm size, 4.76 mm thickness and 0° clearance angle; correct form, tolerance class and fastening ensure secure mounting of the CNMG120412 insert.

Is the insert single‑use or indexable?
This is a double‑sided indexable insert with a central cylindrical hole, allowing rotation and reuse of both cutting edges for economical edge utilisation.

How does the CVD coating affect performance?
The CVD coating improves thermal stability and wear resistance, reducing adhesion and built‑up edge; combined with the carbide substrate it yields a reliable cutting edge life under turning conditions.

What cutting tasks is the corner radius suitable for?
The 1.2 mm corner radius is suitable for general turning and semi‑finishing applications, providing a balance between edge strength and achievable surface finish.
