Reliable machining performance with measurable benefits

The AH8015 grade in this PVD‑coated carbide insert delivers a predictable balance between wear resistance and edge toughness, which translates into longer cutting life under mixed cutting conditions. By combining a rhombic geometry with a 55° approach angle and a low 0.4 mm corner radius, the geometry supports stable chip control and consistent surface finish during both light and moderate cutting operations. The double‑sided chipbreaker reduces the need for frequent index changes and helps maintain productivity in batch turning.

Clear guidance on compatibility and mounting

Compatibility with toolholders is defined by insert form, clearance angle and tolerance class; this plate's ISO designation, rhombic profile and cylindrical hole ensure straightforward matching to standard DNMG‑compatible holders. The 4.76 mm plate thickness and the central hole style allow secure clamping with a screw and clamp assembly commonly used for indexable turning systems. For workshop planning, the system typically comprises the insert, a matched external holder or boring bar, a backing pad or clamp set and replacement screws.

Material capability and grade advantages explained

The AH8015 cutting grade is formulated as a first choice for machining heat‑resistant alloys, offering stable wear behaviour without sacrificing edge integrity. The PVD‑coated layer enhances thermal resistance and reduces built‑up edge tendency when turning alloys that tend to work‑harden. In practice, this means fewer interruptions for insert changes and a more consistent part quality, which supports predictable cycle times and reduced rework. For general turning tasks of tougher materials, the combination of carbide substrate and surface coating provides a cost‑efficient compromise between tool life and process stability.

FAQ

What materials is this insert suitable for?
The DNMG150404 AH8015 insert from Tungaloy is designed primarily for machining heat‑resistant alloys and offers a balanced performance between wear resistance and edge stability for these materials.

How is the insert mounted in a holder?
Mounting uses the central cylindrical hole together with a compatible clamp or screw system; the insert's ISO DNMG form and 4.76 mm thickness match standard DNMG holders.

Is the chip control preformed or application dependent?
The insert includes a double‑sided chipbreaker incorporated into its geometry; chip control performance depends on workpiece material, cutting parameters and chosen holder stability.

What does the AH8015 grade mean for tool life?
AH8015 is a PVD‑coated carbide grade optimised to combine wear resistance and edge security, supporting longer cutting intervals on demanding alloys without compromising surface quality.

Can the corner radius be used for finishing passes?
The 0.4 mm corner radius offers a compromise between edge strength and surface finish, making it suitable for medium‑finish operations where both durability and part appearance are important.
