CNMG120408 AH6235 CNMG 120408 turning insert (ISO) by Tungaloy

The CNMG120408 AH6235 is an ISO-standard rhombic turning insert for external and internal turning, optimised for rostfreier Stahl and interrupted cuts.

• PVD-coated carbide AH6235 for rostfreier Stahl
• Rhombic ISO insert CNMG 120408, 80° geometry
• Double-sided chipbreaker, suitable for interrupted cuts
• Cylindrical hole, 0° clearance, 0.8 mm corner radius

Consistent performance on rostfreier Stahl with PVD-coated carbide

The insert combines a PVD-coated wear layer with a tough AH6235 grade to balance wear resistance and fracture toughness. This makes it particularly suitable for machining rostfreier Stahl, where built-up edge and material workhardening are common challenges. The PVD process deposits a hard, thin film that improves abrasion resistance without excessively reducing edge toughness; as a consequence, the insert sustains longer cutting intervals and maintains dimensional stability under varying cutting conditions. The integrated chip-control geometry promotes predictable chip formation, lowering the risk of chip-related interruptions.

Secure clamping and ISO compatibility for predictable machining

Designed to the ISO CNMG120408 specification, the insert features an 80° geometry, a 0.8 mm corner radius and a 4.76 mm plate thickness, with a cylindrical hole for positive location in compatible holders. These dimensional standards ensure interchangeability and simple replacement in standard turning toolholders; compatibility depends on matching form, clearance, tolerance class, fixation and thickness. The rhombic form and 0° clearance angle allow for versatile use in both external and internal turning operations while the double-sided design offers cost-efficient indexing, effectively doubling the usable cutting edges per insert.

Operational benefits: uptime, stability and economical machining

By combining a robust substrate with targeted coating technology, the insert improves process stability during interrupted cuts and applications with elevated breakout risk. The double-sided chipbreaker reduces vibration and supports consistent surface finishes, which contributes directly to higher productivity and fewer reworks. For production environments where reliable repeatability matters, the ISO-standard geometry and precise tolerances mean predictable tool life and easier tool management. For equipment selection and machining parameters, Metav Werkzeuge provides practical technical guidance and can advise on selecting the correct chipbreaker and grade for specific materials and stability conditions.
