CNMG 090404 AH8015 turning insert by Tungaloy — PVD-coated carbide, rhombic 09

The CNMG090404 AH8015 is an ISO indexable turning insert designed for general turning of heat-resistant alloys and for a wide range of external and internal turning operations.

• PVD-coated AH8015 carbide grade
• Rhombic 09 geometry, CNMG form
• 0.4 mm corner radius for controlled cutting
• Double-sided insert with cylindrical hole

Boosted productivity with a balanced carbide grade

The insert’s PVD-coated carbide substrate in grade AH8015 is engineered for a compromise between wear resistance and cutting-edge stability, making it a practical first choice for machining heat-resistant alloys. The protective coating reduces adhesive wear and helps preserve the cutting edge at elevated temperatures, which translates into longer effective tool life and fewer indexings. In production settings this balance lowers downtime and improves process stability, supporting a predictable rate of component output and reduced tooling costs per part.

Precise geometry for consistent turning performance

Manufactured to the ISO indexable insert standard 090404, the rhombic CNMG shape with an included angle of 80° delivers a dependable cutting profile for both facing and turning. The 0° clearance and a 0.4 mm corner radius provide a defined contact condition that improves part finish and repeatability when paired with a suitable toolholder. The insert is double-sided and features a cylindrical hole for secure clamping; its 4.76 mm thickness contributes to rigidity under typical cutting parameters. Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening, size and thickness — matching these parameters ensures correct seating and clamping force for safe, repeatable turning.

Practical system advantages and recommended use

As an ISO-format indexable solution, the insert is intended to be used with an appropriate external holder or boring bar, together with a shim/retention set and replacement fastening screws; this system approach simplifies insert changes and supports consistent tool positioning. Selection of a suitable chipbreaker and the AH8015 grade should be aligned with the workpiece material, machining type and machine/tooling rigidity to achieve optimal chip control and surface quality. The economical nature of an indexable, double-sided insert means that component production can be scaled without frequent, time-consuming tool regrinds — a tangible efficiency gain for jobbing and series production alike.

FAQ

What materials is this insert best suited for? The PVD-coated AH8015 grade is optimised for machining heat-resistant alloys and offers a versatile balance of wear resistance and edge stability for general turning applications.

How does the CNMG geometry affect holder selection? The CNMG rhombic form, 80° included angle and 0° clearance require a matching ISO-compatible holder whose form, tolerance class and fastening correspond to the insert’s dimensions for secure clamping and accurate positioning.

Is the insert reversible and how many cutting edges are available? The insert is double-sided, providing two usable cutting edges per side depending on indexability and correct orientation in the compatible holder; this improves economy compared with single-edge solutions.

Which chipbreaker should be chosen for reliable chip control? The chipbreaker must be selected according to the workpiece material, machining type and machine/fixture rigidity; pairing the AH8015 grade with an appropriate double-sided chipbreaker yields improved chip formation and surface finish.
