DNMG 150404 AH8015 indexable turning insert by Tungaloy — PVD‑coated carbide, rhombic 55°

The DNMG150404 AH8015 is an ISO‑standard rhombic turning insert designed for general turning of heat‑resistant alloys and similar demanding materials.

• ISO DNMG 55° rhombic geometry
• PVD‑coated carbide AH8015 for alloys
• Double‑sided chipbreaker for versatile turning
• Cylindrical locating hole and 0° relief angle

Optimised grade for heat‑resistant alloys and balanced wear

The AH8015 grade is a PVD‑coated carbide developed as a first choice for the general machining of heat‑resistant alloys. The coating enhances surface hardness and reduces adhesive wear while the substrate provides edge stability; this combination results in predictable tool life under varied cutting conditions. For production environments where material mix and moderate cutting parameters are common, the beneficial trade‑off between wear resistance and cutting‑edge robustness supports consistent component quality and reduced tool change frequency.

Geometry and tolerances that ensure secure clamping and repeatable results

The insert follows the ISO DNMG150404 designation and features a 55° rhombic geometry, a 0.4 mm corner radius and a 4.76 mm thickness, together with a cylindrical locating hole. These measurable attributes ensure compatibility with standard holders when form, relief angle, tolerance class, fastening method, size and thickness are matched. A correctly matched insert and holder combination reduces vibration and run‑out, improving surface finish and extending insert life; specifying the ISO code and physical dimensions at ordering avoids mismatches and downtime.

Efficient turning performance and cost‑effective use

The double‑sided chipbreaker and reversible design make this indexable insert an economical option for both external and internal turning applications. Using both cutting edges maximises material yield per insert and reduces tool inventory. When the grade and chipbreaker are selected according to workpiece material and machine rigidity, the result is stable chip control, fewer interruptions for tool changes and a measurable improvement in throughput. In practice, this leads to more predictable cycles and lower unit costs across typical batch sizes.

Practical mounting guidance and application recommendations

As an ISO‑type indexable insert, correct mounting and torque settings are essential: ensure the holder accepts DNMG geometry, confirm the 0° relief angle matches the toolholder seat and use the specified clamping screws. Inspect seats for cleanliness and light burrs before assembly to preserve the repeatability of clamping. For less experienced teams, choosing the appropriate chipbreaker and grade for the workpiece—especially with heat‑resistant alloys—will reduce trial‑and‑error and safeguard surface quality.

FAQ

What materials is this insert designed for?
The DNMG150404 AH8015 insert by Tungaloy is designed primarily for heat‑resistant alloys; the PVD‑coated carbide AH8015 offers a balanced combination of wear resistance and edge stability suited to such materials.

Will this insert fit my existing DNMG holder?
Compatibility depends on holder form, relief angle, tolerance class, fastening and seat dimensions; the DNMG150404 designation and the listed thickness of 4.76 mm should be checked against the holder specifications.

How does the double‑sided chipbreaker affect tool life?
The double‑sided chipbreaker allows both edges to be used, effectively doubling the available cutting edges per insert and improving cost efficiency while maintaining consistent chip control.

Is the locating hole important for setup?
Yes, the cylindrical locating hole and correct seat geometry ensure repeatable clamping and minimal run‑out, which benefits surface finish and insert life.

What support is available for selecting the correct chipbreaker and grade?
Metav Werkzeuge can advise on selecting the appropriate chipbreaker and the AH8015 grade for the specific workpiece material and machining conditions to optimise performance.
