TNMG 160408 AH8015 indexable insert for turning — Tungaloy

The TNMG160408 AH8015 indexable insert is an ISO-standard triangular insert designed for general external and internal turning of heat‑resistant alloys, combining a PVD coating with a balanced carbide grade for wear resistance and edge stability.

• PVD-coated cemented carbide AH8015
• 0.8 mm corner radius for edge stability
• ISO 160408 triangular insert, 60° angle
• Double-sided chipbreaker, cylindrical hole

High productivity from a balanced carbide and coating

The combination of AH8015 grade cemented carbide and a PVD coating delivers a balanced mix of wear resistance and cutting-edge stability, making the insert well suited to the routine machining of heat‑resistant alloys. This results in predictable tool life and consistent surface finishes, which supports lean production and reduces unplanned tool changes. The slightly larger corner radius contributes to edge robustness, improving resistance to notch wear during interrupted cuts while maintaining acceptable surface quality.

Clear compatibility and practical mounting guidance

Designed to the ISO 160408 form with a 60° geometry and a cylindrical hole, the insert is compatible with holders that match the form, clearance, tolerance class, fastening method, size and thickness. The 0° clearance angle specifies the relief geometry required by the toolholder; a matched holder ensures correct seating and clamp force for stable cutting. The double‑sided chipbreaker provides two usable cutting edges per indexation, allowing economical usage without compromising chip control in many conventional turning setups.

Application focus and selection advice for process security

When selecting an insert grade and chipbreaker, attention to workpiece material and machining stability is essential. The AH8015 grade is the recommended first choice for the general machining of heat‑resistant alloys because it offers effective wear resistance while maintaining a stable cutting edge. For external and internal turning tasks, pairing the insert with a suitable outer holder, backing pad and replacement screws forms a complete system for reliable performance. The ISO series construction simplifies replacement and inventory management across machines and shifts.
