CNMG 120404 T9225 — indexable insert for turning by Tungaloy, rhombic geometry, 0° clearance

A CNMG 120404 T9225 indexable insert for turning, engineered as an ISO-standard rhombic insert for medium to heavy steel machining with a robust universal grade and CVD coating.

• CVD-coated carbide for robust performance
• Universal grade for medium to heavy steel
• Rhombic CNMG shape, 80° included angle
• Double-sided chipbreaker, with cylindrical hole

Higher throughput from a robust universal grade

The combination of a CVD-coated surface and a wear-resistant carbide substrate delivers a strong performance profile for batch and single-part production. The T9225 grade is a robust universal grade optimised for changing engagement conditions and light interruptions; this means fewer insert changes and improved machine utilisation. The result is measurable efficiency gains on the shop floor through longer tool life and predictable process windows, supporting tighter production schedules and lower cost per finished part.

Reliable cutting geometry for consistent surface quality

The rhombic CNMG geometry with an 80° included angle and 0° clearance produces stable cutting conditions on external and internal turning operations. The 0.4 mm corner radius helps to balance edge strength and surface finish, reducing vibration on less rigid setups while maintaining acceptable roughness values. The double-sided chipbreaker provides two usable edges per face, improving economy without sacrificing chip control. Technical users unfamiliar with chipformers will find that a correctly matched chipbreaker reduces rework and protects inserts from premature fracture.

System compatibility and easy integration with holders

As an ISO-standard indexable insert, compatibility with external holders or boring bars is dictated by shape, clearance angle, tolerance class, fastening method, size and thickness. The insert thickness of 4.76 mm and nominal size 12 mm align with common CNMG holders; the central cylindrical hole and secure fastening ensure repeatable clamping and positional accuracy. Specifying this insert within a full system — insert, appropriate external holder, shim/clip and replacement screws — simplifies procurement and reduces setup time at the machine.

Application-focused grade selection and process stability

Designed for turning of steel under medium to heavy cutting conditions, the grade offers stable chip formation across a broad range of steels and cutting speeds. The CVD-layered structure enhances thermal resistance and edge life during sustained cutting, while the universal character of the grade supports varying feed rates and intermittent cuts. For process engineers aiming for consistent results, the insert provides a balance between performance and robustness that supports repeatable part quality and predictable tool-change intervals.
