DNMG150408 AH8015 indexable turning insert — PVD‑coated carbide, 55° rhombic, Tungaloy

A DNMG150408 AH8015 indexable turning insert engineered for ISO‑standard external and internal turning of heat‑resistant alloys, offering balanced wear resistance and edge stability.

• ISO rhombic DNMG shape, 55° cutting angle
• PVD-coated carbide AH8015 for heat-resistant alloys
• Double-sided chipbreaker, cylindrical hole for secure fit
• 0° relief and 0.8 mm corner radius for robust edge

Longer tool life and consistent wear behaviour for demanding alloys

The PVD‑coating applied to the AH8015 grade provides a controlled balance between wear resistance and cutting-edge stability, which translates into extended indexable insert life and fewer interruptions for tool changes. This makes the insert especially suited to machining heat‑resistant alloys where thermal loads are significant. The coating reduces adhesion and built‑up edge, so batch runs remain consistent and scrap rates fall, supporting predictable production planning and cost‑efficient throughput.

Simple compatibility and secure clamping reduce setup uncertainty

Supplied in the ISO rhombic DNMG format with a cylindrical hole, this insert is compatible with standard external holders when form, clearance angle, tolerance class, fastening and thickness match. The double‑sided chipbreaker design offers multiple indexing options, improving value per insert, while the 0° relief angle assists in achieving repeatable seating and orientation. Clear identification of form and dimensions streamlines holder selection and minimises setup time on the shop floor.

Improved chip control and surface integrity for reliable finishing

A 0.8 mm corner radius combined with the rhombic 55° geometry supports robust edge strength without sacrificing surface finish. The integrated chipbreaker is optimised for general turning; selecting the appropriate chipbreaker and grade for the workpiece and machining conditions enhances chip control and helps maintain an even surface quality. For internal and external turning, this design contributes to lower vibration and stable cutting forces, which aids consistent part accuracy and finish.

FAQ

What materials is this insert suited for?
The AH8015 grade is a PVD‑coated carbide developed as a first choice for machining heat‑resistant alloys; it provides a balance between wear resistance and edge stability for demanding materials.

Is the insert compatible with standard DNMG holders?
Compatibility depends on holder form, clearance, tolerance class, fastening and thickness; the DNMG150408 geometry and cylindrical hole ensure compatibility with ISO‑compliant holders when those parameters match.

How many cutting edges are available per insert?
The double‑sided chipbreaker design offers multiple usable edges through indexing; this increases the number of operations achievable before replacement.

What benefits does the 0.8 mm corner radius bring?
A 0.8 mm radius enhances edge strength and process reliability, supporting improved surface finish and reduced risk of chipping in interrupted cuts.

Can this insert be used for internal turning?
Yes — the rhombic DNMG form and the balanced AH8015 grade make the insert suitable for both external and internal turning applications when correct holder geometry is used.
