DNMG 150616 AH8015 Tungaloy turning insert — rhombic 55° geometry, 1.6 mm radius

A DNMG150616 AH8015 Tungaloy turning insert designed for ISO-standard external and internal turning, offering a balanced compromise between wear resistance and edge stability for heat-resistant alloys.

• PVD-coated carbide AH8015
• 55° rhombic geometry for accurate cuts
• 1.6 mm corner radius for robust edges
• Double-sided chipbreaker for cost-efficient use

Maximised process consistency through controlled chip formation

The combination of a PVD-coated carbide grade and a double-sided chipbreaker ensures consistent chip control, reducing cycle-time variability in batch production. The coating increases surface hardness and heat resistance, which slows flank wear and helps maintain the cutting edge under interrupted cuts or elevated temperatures. For operations in stainless and heat-resistant alloys, this translates into longer dwell between indexings and steadier dimensional results, improving throughput and reducing rework rates.

Geometry tuned for dimensional accuracy and surface quality

A 55° rhombic geometry with a 1.6 mm corner radius provides a stable cutting edge that balances strength and finish quality. The geometry supports both finishing and semi-finishing passes: the angle reduces radial engagement for predictable cutting loads, while the corner radius helps achieve smoother surface finishes without compromising edge life. The 0° clearance angle and a cylindrical locating hole ensure secure seating in the holder, which is essential for repeatable part tolerances in production runs.

Clear guidance for application and material selection

Intended primarily for external and internal turning, the insert is particularly suitable for heat-resistant alloys when the AH8015 grade is selected. The grade offers a compromise between wear resistance and edge stability, meaning fewer unexpected edge failures during tough cuts. PVD coating is a thin, hard layer that improves resistance to adhesion and diffusion wear; it is helpful to choose the chipbreaker style and cutting parameters according to workpiece material and machine rigidity to exploit the insert’s strengths.

Cost-effective system integration and workshop benefits

Being double-sided and ISO-standard, the insert offers economical utilisation: two indexable edges per side before replacement lowers tooling cost per component. Compatibility with the holder depends on form, clearance, tolerance class, fixing method, size and thickness, so pairing the insert with the correct clamping set and replacement screws is important for secure assembly. The modular system—insert, matching external holder or boring bar, shim and fixing hardware—streamlines inventory and reduces setup time on the shop floor.
