DNMG110402 AH8015 — Indexable turning insert, PVD‑coated cemented carbide, 55° rhombic (Tungaloy)

The DNMG110402 AH8015 is an ISO‑standard, 55° rhombic indexable insert designed for external and internal turning, optimised for the general machining of heat‑resistant alloys and mixed‑material production tasks.

• PVD-coated cemented carbide grade AH8015
• 55° rhombic form DNMG for versatile turning
• Double-sided chipbreaker, cylindrical hole
• 0.2 mm corner radius, 4.76 mm plate thickness

Reliable edge stability for demanding alloys

The insert combines a PVD-coated surface with a cemented carbide substrate to deliver a balanced mix of wear resistance and edge strength. For firms machining heat‑resistant alloys, this balance reduces flank wear and maintains dimensional stability over longer tool life, which supports predictable cycle times and fewer insert changes. The grade is selected to resist the thermal and abrasive stresses typical of high‑temperature alloys while preserving the cutting edge.

Secure clamping and ISO compatibility that save setup time

Built to the ISO DNMG format, the insert matches standard holders by form, relief angle and thickness; the 55° geometry enables a wide range of turning operations. The cylindrical hole and standard tolerance class ensure consistent seating in the clamp and reliable repeatability, reducing the risk of runout and vibration during cutting. This compatibility shortens setup and tool‑change procedures on mixed machine fleets.

Efficient chip control and stable cutting performance

Featuring a double-sided chipbreaker, the design assists in fragmenting chips across different cutting conditions, which is especially helpful for interrupted cuts and variable feed rates. The combination of chip control and the 0.2 mm corner radius supports a good surface finish while guarding the cutting edge against overloads. Evening out chip flow decreases toolholder stress and increases productivity on continuous turning operations.

Key dimensions and material benefits explained

The insert’s 4.76 mm thickness and rhombic geometry contribute to mechanical stability under load, while the 55° angle provides a compromise between feed versatility and strength at the cutting edge. The PVD coating improves resistance to adhesive and abrasive wear and is particularly effective when machining materials that generate heat at the cutting zone. For general turning tasks and for first‑choice applications on heat‑resistant alloys, this combination of geometry, thickness and coating offers a dependable solution.

FAQ

Which materials is this insert best suited for?
The DNMG110402 AH8015 insert is optimised for heat‑resistant alloys and general machining tasks where a balance of wear resistance and edge stability is required.

How does the AH8015 coating affect tool life?
The PVD coating on the AH8015 grade reduces adhesive and abrasive wear, extending insert life under thermal load and improving consistency of results over repeated cycles.

Is the insert compatible with standard DNMG holders?
Yes. The insert conforms to the ISO DNMG format; form, relief angle, thickness and the cylindrical hole ensure correct seating in standard DNMG holders when the holder specification matches the insert dimensions.

What surface finish can be expected with a 0.2 mm corner radius?
A 0.2 mm corner radius delivers a balance between edge strength and surface finish, offering improved tool life while still achieving good surface quality in finishing and medium‑duty turning operations.

Can the double‑sided chipbreaker be used for interrupted cuts?
The double‑sided chipbreaker improves chip control across varying feeds and interrupted cuts, promoting safer chip evacuation and stable machining in mixed‑operation environments.
