CNMG090404 AH120 — ISO turning insert (CNMG) by Tungaloy

A CNMG090404 AH120 indexable insert for turning, designed for ISO-standard holders and optimised for situations requiring a sharp cutting edge and high process security.

• PVD-coated AH120 carbide grade
• Double-sided chipbreaker for chip control
• Rhombic CNMG 09 geometry, 80° approach
• 4.76 mm thickness with cylindrical hole

Consistent cutting performance through optimised grade and geometry

The combination of a PVD-coated surface and a wear-resistant carbide substrate provides a stable cutting edge that resists flank wear and micro-chipping. The grade emphasises process security, maintaining dimensional stability across extended runs. The rhombic shape and the double-sided chipbreaker contribute to controlled chip formation, which reduces the likelihood of built-up edge and improves surface finish. These factors result in fewer tool changes and better machine utilisation during turning operations.

Secure clamping and easy integration with ISO holders

The insert’s CNMG geometry and the presence of a cylindrical hole enable reliable locating and secure fastening in compatible external holders or boring bars. The 0° clearance specification and a plate thickness of 4.76 mm increase rigidity at the cutting zone, aiding vibration damping and repeatable performance. Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; maintaining these parameters ensures quick insert changes and predictable machining results.

Versatile suitability and straightforward technical advantages

Designed for general turning, the insert supports both external and internal turning when paired with the appropriate chipbreaker and grade selection. The PVD coating improves resistance to abrasive wear and heat, making the insert suitable where a sharp edge and good wear resistance are required. Choosing the correct chipbreaker for the workpiece material and machining stability delivers cleaner chips and reduces part rework, translating directly into time savings on the shop floor.

Productivity gains and reliable brand performance

Using a standardised ISO insert geometry reduces tooling complexity and inventory overhead while enabling fast replacement and minimal setup time. The AH120 grade targets a balance between wear resistance and edge toughness, promoting long tool life and stable metal removal rates. Together, geometry, coating and grade produce predictable results that support consistent cycle times and improved overall equipment effectiveness — a practical advantage for precision turning shops and production environments.
