CNMG090408 AH8015 CNMG indexable insert for turning by Tungaloy — PVD‑coated carbide, double‑sided chipbreaker

CNMG090408 AH8015 is an ISO‑standard rhombic insert designed for general turning applications where a balanced combination of wear resistance and edge stability is required

• ISO‑standard rhombic CNMG insert
• PVD‑coated AH8015 carbide grade
• For heat‑resistant alloys and general turning
• Double‑sided chipbreaker for cost efficiency
• Cylindrical hole for secure clamping

Consistent cutting performance for heat‑resistant alloys

The AH8015 grade is a PVD‑coated carbide developed as a first choice for the general machining of heat‑resistant alloys, delivering a balance between wear resistance and edge stability. This composition supports sustained cutting conditions common in aerospace, power generation and other high‑temperature alloy work, helping to maintain dimensional accuracy and surface quality over longer tool life. Where high thermal loads occur, the coating reduces flank wear and helps preserve the cutting edge for predictable tool‑change intervals.

Reliable fit and secure clamping reduce setup variability

The rhombic CNMG format conforms to ISO dimensions, so compatibility with external holders is determined by form, relief angle, tolerance class, clamping method, size and thickness. The insert features a cylindrical hole for consistent clamping and a corner radius of 0.8 mm, which offers a compromise between toughness and surface finish. The plate thickness 4.76 mm and the 80° insert angle aid in stable engagement during both external and internal turning, reducing chatter and contributing to repeatable results on standard CNMG toolholders.

Economic machining through indexability and chip control

Being double‑sided with a dedicated chipbreaker on each usable edge, this insert doubles the available cutting edges before replacement, lowering per‑edge cost and improving process economy. The integrated chipbreaker is matched to general turning tasks; when paired with a suitable holder and cutting parameters, it promotes controlled chip formation and evacuation. The combination of a robust substrate and PVD coating reduces unplanned interventions, supporting higher productivity and predictable throughput in serial and batch production.

Practical selection and handling advice for secure results

For best results, choose a chipbreaker and grade that match the workpiece material, machining mode and system rigidity; the AH8015 grade is particularly suited for alloys that demand thermal resilience. Confirm holder compatibility by checking form, free angle and tolerance class rather than relying solely on nominal ISO designation. Inserts are reversible; ensure correct orientation and torque for clamping screws to prevent slippage. If further machining data or parameter recommendations are required, technical advice is available to align insert choice with cycle‑time and surface‑finish targets.
