CNMG090404 AH6225 — ISO-indexable turning insert for turning (Tungaloy)

The CNMG090404 AH6225 is an ISO-indexable turning insert designed for external and internal turning operations, delivering a sharp yet resilient cutting edge for medium machining of rostfreier Stahl and similar materials.

• PVD-coated carbide grade AH6225
• Rhombic 80° geometry with cylindrical hole
• Double-sided chipbreaker for stable chips
• Corner radius 0.4 mm, 4.76 mm thickness

Enhanced process stability through geometry and grade

The rhombic 80° geometry combined with a 0.4 mm corner radius delivers consistent engagement and predictable cutting forces, which is especially beneficial for medium steel-turning applications. The PVD-coated carbide composition of the grade provides improved wear resistance under variable cutting conditions, so the tool maintains edge integrity over longer periods. These characteristics translate into fewer interruptions for regrinding or replacement and steadier machining results in series production.

Reliable chip control and predictable tool life

A double-sided chipbreaker supports controlled chip formation across a range of feeds and depths, reducing the risk of entanglement and stabilising surface finish. The coating system on this grade is optimised to protect the substrate while preserving a sharp cutting edge, enabling efficient metal removal without sacrificing edge stability. For operations on rostfreier Stahl, the combination of chip control and edge protection helps avoid work hardening and minimises the need for secondary finishing—an efficiency gain for busy workshops.

Simple integration with ISO tooling systems

Designed as an ISO-standard insert, the component fits holders compatible with form, relief angle, tolerance class, fastening, size and thickness criteria; the cylindrical hole allows secure clamping and straightforward indexing. The insert’s 4.76 mm thickness and rhombic shape suit a wide range of external and internal turning holders. Clear dimensional standards reduce setup time and support rapid replacement during tool changes, contributing to reduced machine downtime and easier inventory management.

Efficiency and quality benefits for everyday production

By combining a wear-resistant coating with a geometry aimed at stability, this insert balances cutting performance and service life to deliver measurable cost benefits over time. The design is particularly suited to medium-duty turning where surface finish and repeatability are priorities. Choosing this grade supports consistent part quality while keeping maintenance predictable—helpful for scheduling and process planning in production environments.
