TNMG160408 AH8015 Tungaloy turning indexable insert — PVD-coated carbide, 0.8 mm corner radius

The TNMG160408 AH8015 is an ISO-standard triangular turning insert, engineered for external and internal turning of heat-resistant alloys with a balance of wear resistance and cutting-edge stability

• PVD-coated carbide for extended tool life
• ISO-standard triangle, 60° included angle
• 0.8 mm corner radius for stable cutting edges
• Double-sided chipbreaker with cylindrical hole

Predictable wear life and reliable process stability

The PVD-coated carbide grade AH8015 delivers a controlled compromise between wear resistance and edge stability, making the insert a dependable choice for machining heat-resistant alloys. The coating reduces flank wear under elevated temperatures while the substrate maintains fracture resistance; the result is a more predictable tool life and reduced frequency of index changes, which supports continuous production runs and higher machine uptime. This performance-oriented design contributes directly to improved cycle-time consistency and fewer unscheduled interruptions.

Straightforward system integration for rapid setup

As an ISO-standard triangular insert, compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness; the indexable geometry simplifies selection for standard holders. The insert is triangular with a 60° included angle, a 16 mm edge length, 4.76 mm thickness and a 0° relief angle, plus a cylindrical hole for positive clamping. These measurable parameters enable quick verification against existing toolholders and reduce setup time on the shop floor. Clear dimension matching ensures secure fastening and consistent cutting geometry without trial-and-error fitting.

Improved chip control and surface quality with a double-sided chipbreaker

The double-sided chipbreaker is configured to shape and evacuate chips consistently, which lowers the risk of chip entanglement and stabilises cutting forces during turning operations. Controlled chip formation supports a more uniform surface finish and reduces the need for rework. The 0.8 mm corner radius further moderates cutting forces and promotes smoother transitions on the machined profile, particularly in light to medium turning passes where edge strength and finish are both critical.

Grade selection and practical application guidance

The AH8015 grade is recommended as a first choice for general machining of temperature-resistant alloys where an even balance of edge life and toughness is required. For best results, select a chipbreaker and sort that match the workpiece material, machining strategy and machine rigidity; the complete system comprises the indexable insert, a suitable external holder or boring bar, a backing/clamping set and replacement screws. Metav Werkzeuge can assist with selection to ensure the insert functions optimally within the intended machining environment.
