DNMG150404 AH8015 — DNMG indexable insert for turning, Tungaloy

DNMG150404 AH8015 is an ISO‑standard rhombic indexable insert designed for precise external and internal turning of heat‑resistant alloys in general machining applications

• PVD‑coated carbide grade AH8015
• ISO DNMG 150404 rhombic form
• Double‑sided chipbreaker design
• Cylindrical hole fastening for secure seating

Durable coating and balanced grade for longer tool life

The PVD‑coated carbide of the AH8015 grade offers a deliberate balance between wear resistance and cutting‑edge stability, which translates into extended productivity and fewer unexpected tool changes. A PVD layer reduces abrasive and adhesive wear at the cutting edge, while the substrate carbide provides toughness under intermittent cutting. For workshops processing heat‑resistant alloys, this combination typically delivers a consistent surface finish and longer tool life, reducing overall machining costs.

Geometry optimised for versatile turning performance

The rhombic DNMG form with a 55° geometry and a 0.4 mm corner radius provides a compromise between strength and cutting action: the acute approach angle aids in finishing and light‑turning operations, while the moderate corner radius supports controlled edge strength for semi‑roughing. As an ISO‑standard insert, the form and dimensions are compatible with a wide range of holders, but correct matching requires attention to holder form, clearance, tolerance class, fastening method, size and thickness to ensure stable cutting conditions.

System compatibility and practical handling benefits

This indexable plate is supplied with a cylindrical hole for screw fastening and a double‑sided chipbreaker, allowing re‑indexing to present a fresh edge without replacing the insert. The plate measures an inscribed circle of 15 mm with a 4.76 mm thickness, which contributes to clamping stability in the seat and reduces vibration tendency. System setup should include a matching outer holder or boring bar, a suitable clamp set and correct replacement screws to maintain repeatable positioning and process reliability.

Productivity advantages and recommended applications

Selected as a first choice for general machining of heat‑resistant alloys, the AH8015 grade supports productive cutting by offering consistent wear behaviour and dependable edge performance. The combination of geometry and coating reduces downtime associated with frequent insert changes and simplifies tool‑life planning, contributing to faster set‑ups and predictable parts quality.

FAQ

What materials is this insert best suited for?
The DNMG150404 AH8015 insert is optimised for heat‑resistant alloys; the AH8015 PVD‑coated carbide provides a balance between wear resistance and cutting‑edge stability for general turning tasks.

How is compatibility with tool holders ensured?
Compatibility depends on form, clearance, tolerance class, fastening method, size and thickness; the ISO‑standard DNMG150404 geometries permit interchangeability with holders designed to accept DNMG inserts.

Can this geometry be used for both external and internal turning?
Yes; the rhombic shape with a 55° approach angle and the 0° rake make the insert suitable for external and internal turning when paired with an appropriate holder or boring bar.

How is the insert clamped in the tool?
The plate features a cylindrical hole for screw fastening; use the matching clamp set and replacement screws as part of the system arrangement to achieve secure seating and repeatable positioning.

What are the practical benefits of the AH8015 grade from Tungaloy?
The AH8015 grade combines a PVD coating with a tough carbide substrate to provide stable cutting performance, good wear resistance and reliable edge life for productive machining of demanding alloys.
