DNMG110408 AH8015 Tungaloy turning insert — PVD-coated cemented carbide, 0.8 mm radius

A DNMG110408 AH8015 indexable insert designed for ISO‑standard external and internal turning of heat‑resistant alloys and general turning applications.

• ISO-standard rhombic insert DNMG110408
• PVD-coated cemented carbide AH8015
• 0.8 mm corner radius for edge strength
• Double-sided chipbreaker, cylindrical hole

Consistent wear performance for demanding alloys

The PVD-coated cemented carbide composition in grade AH8015 offers a balance between wear resistance and edge stability, making the insert suitable for machining heat‑resistant alloys under varied cutting conditions. As an ISO-standard component, the insert ensures predictable interchangeability with compatible holders; this standardisation reduces setup time and helps maintain a steady production flow. The coating acts as a thermal barrier and improves adhesion, which translates into longer effective cutting life and fewer interruptions in process chains.

Geometry engineered for reliable cutting and secure clamping

The rhombic form with an included angle of 55° and a corner radius of 0.8 mm delivers a compromise between cutting strength and surface finish. A larger radius improves the toughness of the cutting edge and resists chipping, while the geometry still permits precise contour turning. The 0° clearance angle requires appropriate rigidity in the tool assembly, and the cylindrical hole combined with a secure clamping system yields stable fixation and repeatable positioning. The double-sided chipbreaker supports effective chip control and allows indexation to extend service intervals.

Productivity benefits and economical machining

Choosing the AH8015 grade gives a pragmatic trade‑off: enough hardness to resist abrasive wear with sufficient edge toughness for interrupted cuts. The insert’s PVD coating helps at elevated temperatures, improving performance in continuous, high‑temperature turning operations. Reduced wear and reliable edge behaviour lower downtime for insert changes and regrinds, which contributes to improved uptime and cost‑efficiency per machined component. The overall system — insert, suitable holder or boring bar, and proper clamping — is optimised for productive metal removal and consistent results.

Practical guidance for selection and system compatibility

Compatibility with a chosen holder depends on form, free angle, tolerance class, fixing method, size and thickness; ensure the seat and screw arrangement match the insert’s tolerance class and hole style. System components include the indexable insert, an appropriate external holder or boring bar, a support pad or clamp set and replacement screws. Select the chipbreaker and grade based on the workpiece material and machining stability: for less rigid set‑ups or interrupted cuts, favour edge strength; for continuous finishing passes, consider geometries that support improved surface quality and chip evacuation.

FAQ

What materials is this insert suitable for?
The Tungaloy DNMG110408 AH8015 insert is primarily specified for heat‑resistant alloys and similar difficult‑to‑machine materials; the AH8015 grade balances wear resistance and edge stability for general turning tasks.

How does the PVD coating benefit machining performance?
The PVD coating on the AH8015 grade increases thermal resistance and reduces adhesion at the cutting edge, which improves life under higher cutting temperatures and contributes to a more stable machining process with the DNMG110408 insert.

What does the 0.8 mm corner radius affect in practice?
A 0.8 mm corner radius enhances edge strength and resistance to chipping, offering a more robust cutting edge for semi‑roughing and interrupted cuts while still permitting acceptable surface finish for many turning operations.

Is the insert compatible with standard holders?
The ISO designation and format of the DNMG110408 make it compatible with holders that match its form, size, thickness and fixing arrangement; proper holder compatibility and clamping are essential for repeatable performance.

What role does the double‑sided chipbreaker play?
The double-sided chipbreaker supports reliable chip control and allows indexation to extend service life; it improves chip formation across a range of cutting conditions, reducing the need for frequent interventions.

Which system components are required for mounting?
A complete system includes the indexable insert, a matching external holder or boring bar, a support pad or clamp set and replacement screws; correct assembly ensures positional accuracy and process stability with the DNMG110408 insert.
