CNMG 120404 T9235 Wendeplatten - Tungaloy

Take advantage of the combination of CVD‑coated carbide (T9235), ISO CNMG120404 geometry and a 0.4 mm nose radius for reliable turning results in unstable or interrupted cuts; order directly via Metav Werkzeuge or consult their application specialists for tailored recommendations.

CNMG120404 T9235 ISO turning indexable insert — CVD‑coated carbide (Tungaloy)

CNMG120404 T9235 is a rhombic, ISO‑standard indexable insert designed for turning applications, particularly suited to steel machining where interrupted cuts or limited stability demand a tough, wear‑resistant grade.

• CVD‑coated T9235 carbide grade
• ISO CNMG 120404 geometry
• 0.4 mm nose radius for fine finish
• Double‑sided chipbreaker, with cylindrical hole

Consistent cutting performance under unstable conditions

The T9235 grade is a CVD‑coated carbide chosen for its toughness and resistance to chipping at lower cutting speeds. In turning operations where machine or workpiece stability cannot be guaranteed, the tougher microstructure of this grade limits flank and crater wear, extending effective tool life and reducing unexpected interruptions. The 0.4 mm nose radius balances surface finish and cutting forces, enabling improved repeatability when finishing external diameters or performing light profile passes.

Easy integration into ISO‑based tool systems

Compatibility is assured by the ISO CNMG form: ISO CNMG120404 geometry, rhombic shape and standard mounting features make this insert compatible with a wide range of external holders and boring bars. Key parameters that determine a correct fit are form, 0° clearance, tolerance class, fastening method, size and 4.76 mm thickness. A typical system comprises the insert, a matched external holder or boring bar, a shim/clamp set and replacement screws — enabling quick replacement and minimised downtime.

Reliable chip control and secure fixing for steel turning

The double‑sided chipbreaker is tuned for chip segmentation during steel turning, helping to prevent long, stringy chips in interrupted cuts and improving operator safety. The insert is supplied with a cylindrical hole, which supports secure axial clamping and repeatable seating in the pocket. The CVD coating enhances thermal resistance and wear performance on steel; combined with the T9235 substrate it provides a productive solution for machining scenarios where toughness and process security are decisive.

FAQ

What materials is this insert intended for?
This Tungaloy CNMG120404 T9235 insert is intended primarily for steel machining, especially where toughness is needed for interrupted cuts or less stable setups.

How does the T9235 grade behave in interrupted cuts?
The T9235 CVD‑coated carbide offers increased toughness and improved resistance to chipping during interrupted cuts, providing more consistent tool life under unstable conditions.

Which holders fit this insert?
Holders that accept the ISO CNMG120404 form and match the insert’s 0° clearance, size and thickness will be compatible; correct matching considers form, tolerance class and fastening method.

What surface finish can be expected with this geometry?
With a 0.4 mm nose radius and the double‑sided chipbreaker, the insert delivers good surface quality for finishing passes while maintaining controlled cutting forces.

Is the insert reversible or single‑use per edge?
The rhombic CNMG shape with a double‑sided chipbreaker provides multiple usable cutting edges; the insert can be indexed according to wear and application needs.
