CNMG 120404 AH6225 ISO indexable turning insert — PVD-coated carbide, 0.4 mm corner radius — Tungaloy

The CNMG 120404 AH6225 is an ISO‑standard indexable turning insert engineered for external and internal turning, optimised for machining rostfreier Stahl under varying conditions

• ISO CNMG120404 geometry, 80° rhombic
• PVD-coated carbide AH6225 for rostfreier Stahl
• 0.4 mm corner radius for mixed operations

Consistent cutting with a universal grade

The universal AH6225 grade delivers a balance between sharpness and edge stability designed for machining rostfreier Stahl. Its PVD-coated carbide construction combines wear resistance with reliable edge retention, meaning fewer interruptions for insert changes during medium‑duty turning. This results in more predictable cycle times and reduced process variation, which supports leaner production planning and improved component repeatability.

Geometry tuned for controlled chip formation and surface quality

The ISO CNMG120404 rhombic shape with an 80° approach angle and a 0.4 mm corner radius provides a stable cutting geometry that reduces vibration and promotes even wear. The double-sided chipbreaker design manages chips effectively across different feed rates, helping to maintain consistent surface finish and minimise secondary operations. Explaining technical terms: the corner radius influences edge strength and surface finish—smaller radii favour finer detail, while the chosen radius here offers a compromise for versatile turning tasks.

System compatibility that simplifies tool selection

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so the insert integrates into established ISO‑based tool systems without guesswork. The rhombic profile and cylindrical hole make mounting straightforward in matched holders, and the PVD coating ensures process security in interrupted cuts and variable feed conditions. For workshops seeking predictable results, this insert reduces setup variability and supports consistent part quality across batches.

FAQ

What materials is this insert suitable for? The AH6225 grade is a universal PVD‑coated carbide developed for machining rostfreier Stahl and provides reliable performance in medium machining and varying conditions.

How is holder compatibility ensured for this insert? Compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; the CNMG120404 format fits ISO‑standard holders designed for that geometry.

What does the AH6225 grade offer compared with other grades? AH6225 combines a wear‑resistant PVD coating with a balanced carbide substrate to deliver stable edge life and good performance on rostfreier Stahl under changing cutting conditions.

What does 'double‑sided chipbreaker' mean in practice? A double‑sided chipbreaker provides chip control on both usable faces of the insert, improving chip flow and surface finish during external and internal turning operations.
