CNMG 090402 AH8015 — ISO rhombic turning insert, PVD-coated carbide, Tungaloy

CNMG090402 AH8015 is an ISO‑standard rhombic turning insert designed for general turning of heat‑resistant alloys and versatile workshop applications

• PVD-coated carbide grade AH8015
• ISO CNMG 090402 rhombic insert
• Double-sided chipbreaker for stable cutting
• Cylindrical hole for secure clamping
• 0.2 mm corner radius, 80° lead angle

Efficient turning of heat‑resistant alloys with balanced wear resistance

The PVD-coated carbide grade AH8015 offers a balanced combination of wear resistance and edge stability, making it a reliable choice for machining heat‑resistant alloys in general turning operations. The coating reduces built‑up edge and adhesion at elevated temperatures, which translates into longer intervals between indexings and fewer interrupted production cycles. This results in improved process economy while maintaining dimensional stability on workpieces that demand consistent results.

Reduced setup time and dependable clamping for production workflows

As an ISO‑standard insert in the CNMG format, compatibility with holders is determined by geometry, relief angle, tolerance class, fastening and plate thickness. The cylindrical hole and standardised form allow secure positioning and repeatable clamping, which reduces setup time during tool changes and supports predictable tool behaviour across different toolholders. Clear component matching minimises fixture errors and helps maintain cycle time in serial production.

Consistent surface quality and repeatable edge life for finishing demands

The double-sided chipbreaker and a 0.2 mm corner radius contribute to stable chip formation and improved surface quality on external and internal turning operations. The combination of a small corner radius and controlled chip evacuation reduces vibration influence on the cutting edge, yielding a consistent surface finish and repeatable part tolerances. For customers seeking reduced rework and reliable batch uniformity, these characteristics lower overall production costs by limiting scrap and secondary processes.

Practical guidance for application selection and process reliability

Selection of the correct chipbreaker and grade should follow the workpiece material, machining method and set‑up rigidity. In general turning tasks, the rhombic plate form with an 80° lead angle offers a compromise between strength and accessibility for profile work. For demanding or unstable set‑ups, choosing a holder with adequate support and checking tolerances before machining enhances economical machining and extends the useful life of the cutting edge. When assemblies are complex, matching insert geometry to holder specifications preserves productivity and reduces unplanned downtime.
