CNMG 120412 T9225 CNMG — Turning insert by Tungaloy with CVD-coated carbide and rhombic form, 80° included angle

CNMG120412 T9225 Tungaloy turning insert for ISO-standard turning applications, offering a robust universal grade for medium to heavy steel machining

• CVD-coated carbide for extended edge life
• Rhombic form with 80° included angle
• Double-sided chipbreaker for reliable chip control
• Cylindrical-hole design for secure clamping

Consistent cutting performance through CVD-coated carbide

The CVD-coated carbide composition of this insert combines a hard, wear-resistant surface with a tough carbide core to deliver steady cutting-edge retention even under variable engagement. The T9225 grade is formulated as a robust universal solution for medium-to-heavy steel machining, particularly where slightly interrupted cuts or changing cutting conditions demand greater toughness. CVD coating reduces flank wear and maintains profile precision, which translates into more predictable tool life and fewer insert changes per job — a direct improvement to process efficiency and cost control.

Secure fit and geometry that supports stable turning

ISO conformity ensures straightforward selection of matching holders when the correct form, relief angle, tolerance class, fastening style, size and thickness are observed. The rhombic form with an 80° included angle and a 0° relief angle gives a balance between strength and accessibility in external and internal turning. The insert’s cylindrical hole and standard dimensions (thickness 4.76 mm, size 12) enable secure clamping and repeatable indexation on compatible toolholders, while the 1.2 mm corner radius helps manage cutting forces for roughing and medium finishing tasks.

Practical benefits for shop-floor productivity

Designed as a universal grade, this insert suits diverse turning tasks: external and internal turning, and operations with intermittent cuts. The double-sided chipbreaker supports stable chip formation and evacuation across a range of feeds, reducing the risk of built-up edge and improving surface finish. Selecting this grade and chipbreaker combination means shorter set-up times, fewer insert changes and better throughput in batch production. For operators and process engineers, the result is reliable component tolerances and reduced downtime.

FAQ

What materials is this insert suited for?
The Tungaloy CNMG120412 T9225 insert is optimised for medium to heavy steel machining and performs well under slightly interrupted cuts due to its tougher CVD-coated carbide grade.

How does the chipbreaker affect machining?
The double-sided chipbreaker on this insert promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of built-up edge during turning operations.

Which holders are compatible with this insert?
Compatibility depends on the holder matching the ISO form, relief angle, tolerance class, fastening method, size (12 mm) and thickness (4.76 mm); using ISO-compatible holders provides secure clamping and repeatable indexing.

Can this insert be used for internal turning?
Yes — the rhombic form and 80° included angle make the insert suitable for both external and internal turning tasks where accessibility and strength are balanced.

Is the insert indexable and reversible?
The CNMG120412 is double-sided and indexable; rotating or indexing the insert restores a fresh cutting edge and extends effective tool life.
