DNMG110404 AH8015 indexable turning insert — PVD‑coated carbide, 55° rhombic, Tungaloy

The DNMG110404 AH8015 is an ISO‑standard indexable turning insert engineered for general turning of heat‑resistant alloys and a wide range of engineering materials.

• ISO‑standard DNMG geometry
• PVD‑coated carbide grade AH8015
• 55° rhombic shape, 0° clearance angle
• Double‑sided chipbreaker, cylindrical hole

Reliable cutting for demanding alloys

The combination of a PVD‑coated carbide substrate and the AH8015 grade provides a balanced performance between wear resistance and edge stability, making this insert particularly suited to the machining of heat‑resistant alloys. The thin, hard PVD coating reduces adhesive wear and improves surface finish, while the carbide core maintains toughness under interrupted cuts. This balance results in steadier cutting forces and fewer unplanned tool changes, supporting higher process reliability in serial production.

Stable clamping and predictable geometry for accurate turning

The rhombic DNMG form with a 55° main cutting angle and a 0° clearance angle ensures compatibility with a wide range of external holders and boring bars. The insert’s cylindrical hole allows secure fastening in standard clamping systems; compatibility is governed by shape, clearance angle, tolerance class, clamping method, size and thickness. Correct matching of holder and insert reduces vibration and run‑out, which directly improves dimensional accuracy and surface integrity during both external and internal turning.

Efficient machining and lower operating costs

A double‑sided chipbreaker design enables the use of both cutting edges, extending tool life per insert and reducing tooling costs for batch production. The AH8015 grade is optimised for productive chip control across varied cutting conditions, helping to maintain stable cutting zones and fewer interruptions for chip management. In practice this translates into shorter cycle times and more predictable tool replacement intervals, supporting cost‑effective machining strategies without compromising component quality.

Straightforward handling, indexing and application choice

Indexing the insert to present a fresh cutting edge is quick and reliable, thanks to the standardised ISO format and secure hole clamping. For users unfamiliar with coating technology: PVD (physical vapour deposition) applies a very thin, adherent hard layer to the carbide substrate, enhancing wear resistance without significantly reducing toughness. Selection advice — choose the AH8015 grade and the double‑sided chipbreaker when machining heat‑resistant alloys or mixed batches that demand a compromise between durability and edge strength.

FAQ

What materials is this insert intended for? The DNMG110404 AH8015 Tungaloy indexable turning insert (SKU: 6947131‑Tungaloy) is primarily intended for heat‑resistant alloys and general engineering materials where a balance of wear resistance and edge stability is required.

How is the insert clamped in the holder? Clamping is achieved via the cylindrical hole and standard ISO clamping systems; secure fastening depends on matching the insert shape, tolerance class, size and thickness to the holder.

Can both sides of the insert be used? Yes, the insert features a double‑sided chipbreaker allowing both cutting edges to be indexed and used, which extends the service life per insert.

What does the AH8015 grade offer compared with other grades? The AH8015 grade is a PVD‑coated carbide formulation optimised for good wear resistance combined with stable cutting edges, making it a first choice for machining heat‑resistant alloys under varied cutting conditions.

Is the insert suitable for internal boring as well as external turning? The DNMG geometry and the insert’s dimensions make it suitable for both external and internal turning operations, provided the correct holder and clamping arrangement are used.
