CNMG120404 AH6225 indexable turning insert for turning — Tungaloy

CNMG120404 AH6225 is a PVD-coated indexable insert engineered for external and internal turning where a balanced combination of edge sharpness and cutting stability is required

• PVD-coated cemented carbide AH6225
• Optimised for stainless steel machining
• ISO CNMG 120404, 80° rhombic form
• Double-sided chipbreaker, 0.4 mm radius

Consistent cutting performance and wear resistance

The PVD-coated cemented carbide composition of this insert provides a controlled balance between edge sharpness and durability. The AH6225 grade is tailored for machining stainless steels under medium cutting conditions, giving a sharp cutting edge while resisting premature wear. The 80° rhombic geometry supports versatile tool paths, and the double-sided chipbreaker helps maintain stable chip formation, reducing the need for frequent index changes and improving process reliability.

Simple integration with ISO holders and predictable set-up

Compatibility with clamping systems is governed by the insert form, clearance angle (0°), tolerance class, fixing method, size and thickness. The ISO designation CNMG 120404 ensures interchangeability with standard CNMG holders; the insert is supplied with a cylindrical hole for secure fastening. Clear reference values such as 12 mm inscribed circle, 4.76 mm thickness and an 80° form allow straightforward selection of matching holders and clamps, shortening set-up time and lowering handling errors.

Practical economy through stable chip control and application advice

A 0.4 mm nose radius offers improved surface finish on medium-precision turning while the double-sided design extends tool life per insert. Stable chip formation and the AH6225 coating reduce unplanned downtime and increase usable tool life, which supports better cost-efficiency in production. For tailored results, choose the chipbreaker and grade according to workpiece material and machining stability; assistance for optimal parameter selection is available from Metav Werkzeuge specialists.
