DNMG 150612 AH8005 Turning Insert (ISO DNMG) — Tungaloy

A DNMG150612 AH8005 indexable turning insert engineered for stable machining of heat‑resistant alloys and hard materials

• PVD-coated carbide grade AH8005
• ISO rhombic DNMG geometry 55°
• Double-sided chipbreaker design
• 1.2 mm corner radius, 6.35 mm thickness

Increased process stability for heat‑resistant and hard materials

The PVD‑coated cemented carbide grade AH8005 is designed to deliver consistent wear resistance in elevated temperatures and under sustained cutting loads. The PVD coating reduces flank wear and extends usable tool life while preserving cutting edge integrity, which leads to fewer insert changes and reduced machine downtime. For precision turning tasks, the robust substrate and coating combination supports longer uninterrupted production runs and a more predictable maintenance schedule.

Geometry and dimensions that ensure repeatable setup

The ISO rhombic DNMG form with an included angle of 55° and a relief angle of 0° provides predictable cutting engagement and secure seating in a compatible clamping system. The 1.2 mm corner radius and plate thickness 6.35 mm balance edge strength and cutting performance, helping to avoid premature chipping when machining demanding workpieces. Because the insert is ISO‑standardised, interchangeability with suitably specified holders is supported; compatibility is determined by form, clearance angle, tolerance class, fastening and plate size.

Efficient chip control for better surface quality and throughput

A double‑sided chipbreaker is integrated to shape and evacuate chips effectively across a range of cutting conditions, which reduces the need for secondary finishing and improves cycle times. Controlled chip formation contributes directly to improved surface finish and lowers the risk of rework. The insert is intended to be used as part of a system—appropriate external holders, underplates and replacement screws must be chosen to maintain clamping stability and to make full use of the chip control geometry.

Clear application scope and system considerations

Specified for turning applications, the insert is particularly suited to heat‑resistant alloys and harder materials when machining conditions and rigidity are sufficient. ISO‑compliant indexable plates such as this require the correct holder geometry and clamping parts; the system typically comprises the indexable plate, a matched external holder or boring bar, an underplate/clamp set and the correct replacement screws. Selection of the chipbreaker style and grade should be matched to the workpiece material, the machining strategy and the available machine stability to achieve consistent results.

FAQ

What materials is this insert best suited for?
The DNMG150612 AH8005 insert is optimised for heat‑resistant alloys and harder materials thanks to the wear‑resistant PVD‑coated carbide grade AH8005, which maintains edge life under elevated temperatures.

Is the insert compatible with standard DNMG holders?
Yes, the insert follows ISO DNMG geometry; compatibility depends on holder form, free angle, tolerance class, fastening method and plate thickness, so holders specified for DNMG150612 will be compatible.

How does the chipbreaker affect cutting performance?
The double‑sided chipbreaker on this indexable plate improves chip formation and evacuation, which enhances surface finish and reduces the need for secondary operations when the correct chipbreaker is chosen for the workpiece.

Can the insert be used on a boring bar for internal turning?
The indexable plate can be used for internal or external turning provided the chosen boring bar offers the required rigidity and supports DNMG geometry and plate thickness.

How is the insert mounted and indexed?
The plate is secured via the cylindrical hole and clamping system in a compatible holder; the ISO format allows indexing to the unused cutting edges once an edge is worn.
