CNMG090404 AH6225 Tungaloy indexable turning insert — ISO 090404 for turning

The CNMG090404 AH6225 Tungaloy insert is an ISO‑standard indexable turning insert engineered for external and internal turning of stainless steels, offering a sharp, stable cutting edge and a double‑sided chipbreaker for versatile machining.

• PVD-coated AH6225 carbide grade
• ISO CNMG090404 rhombic insert geometry
• Optimised for stainless steel turning
• Double-sided chipbreaker, cylindrical hole

Consistent geometry and a grade optimised for stainless steel

The combination of ISO CNMG090404 geometry and the AH6225 PVD‑coated carbide provides predictable cutting behaviour under varying conditions. The rhombic form and the specified 0° clearance ensure steady contact with the workpiece, reducing chatter and supporting reproducible surface finish. For production environments where process stability matters, this geometry helps maintain cycle times and lowers the need for constant readjustment, so tool changes and setups become more efficient.

Reliable chip control and edge stability for mid‑range turning

A double‑sided chipbreaker and a cutting edge designed for a balance of sharpness and robustness enable consistent chip formation when machining stainless steel. The PVD coating enhances wear resistance and thermal stability during intermittent cuts, which is especially useful in mixed‑batch production or where cutting parameters vary. This leads to fewer unexpected tool failures and a more economical use of tool stock, improving overall shopfloor productivity.

Practical compatibility and handling to simplify tooling decisions

The insert is ISO‑standard and intended for use with matching CNMG holders; compatibility depends on form, relief angle, tolerance class, clamping and thickness. The insert features a cylindrical hole for secure fixing and a 0.4 mm corner radius, making it suitable for general external and internal turning tasks where a balance of edge strength and profile definition is required. Selecting a holder and clamping kit that match the ISO form will ensure correct seat contact and repeatable clamping torque, reducing assembly time and the risk of misalignment.

Economic and operational benefits for workshop use

Using a universal grade such as AH6225 simplifies inventory by covering a broad range of stainless‑steel applications at medium machining parameters. The PVD‑coated carbide provides enhanced tool life in many turning operations, reducing the frequency of insert changes and downtime. For workshops aiming for steady productivity and manageable stock levels, the combination of standardised form, reliable coating and a robust chipbreaking solution supports both planned series production and flexible small‑batch work.

FAQ

What materials is this insert best suited for? The CNMG090404 AH6225 insert from Tungaloy is optimised for stainless steel machining and performs reliably in medium‑range turning operations.

Is the insert reversible and how many cutting edges are available? The indexable design is double‑sided, providing multiple usable edges per insert and economical utilisation of the carbide blank.

Which holders are compatible with this ISO form? Compatibility requires a matching CNMG‑type holder that corresponds to ISO 090404 in form, relief angle, clamping and thickness to ensure correct seating and clamping.

What is the corner radius and how does it affect finishing? The insert has a 0.4 mm corner radius, which balances edge strength with the ability to produce defined contours and acceptable surface finish in general turning.

Can this grade handle changing cutting conditions? Yes; the AH6225 PVD‑coated grade is designed for stable edge life under varying conditions, offering robustness alongside a sharp cutting profile.
