DNMG150408 AH8005 Tungaloy – Indexable Turning Insert, PVD‑coated Carbide, 55°

DNMG150408 AH8005 is an ISO‑standard indexable insert designed for turning operations in demanding materials.

• ISO 55° rhombic geometry
• PVD‑coated carbide AH8005
• 0.8 mm corner radius for strength
• Double-sided chipbreaker, cylindrical hole

Exceptional wear resistance for high‑temperature alloys

The combination of PVD‑coated surface and carbide substrate delivers elevated wear resistance, especially under the thermal and mechanical stress encountered when machining heat‑resistant alloys and other hard materials. The AH8005 grade is formulated for stable cutting conditions and provides a consistent cutting edge life, which reduces the frequency of index changes and supports uninterrupted production. By choosing a coated grade with proven toughness, predictable tool life and repeatable surface quality are more easily achieved, lowering overall machining cost per component.

Stable geometry and secure clamping for repeatable results

The rhombic 55° profile and a 0° clearance angle create a compact cutting geometry that is well suited to both external and internal turning operations where control and rigidity are priorities. The insert’s double‑sided chipbreaker allows multiple indexing positions and consistent chip formation when matched to a suitable holder. Compatibility with ISO holders is governed by form, free angle, tolerance class, fastening type, size and thickness; checking these parameters ensures correct seating and repeatable positioning in the toolholder, translating into predictable dimensional accuracy and surface finish.

Practical machining guidance to maximise productivity

With a 0.8 mm corner radius and a plate thickness of 4.76 mm, this rhombic insert balances edge strength and surface finish: the larger radius increases edge robustness for interrupted cuts, while the geometry still permits fine finishing cuts when machine and setup are stable. The cylindrical hole and standardised dimensions facilitate secure clamping in dedicated holders; selecting an appropriate chipbreaker and stable clamping arrangement will improve chip control and extend usable edge life. For outer and inner turning, choose cutting parameters in line with the workpiece material and the insert’s wear‑resistant properties to achieve efficient, repeatable machining.

FAQ

Is this insert suitable for machining heat‑resistant alloys?
The DNMG150408 AH8005 insert from Tungaloy is specifically formulated for machining heat‑resistant alloys and other hard materials, offering high wear resistance under thermal stress.

What materials is this grade intended for?
The AH8005 grade is intended for heat‑resistant alloys and hard workpiece materials where stable cutting conditions and wear resistance are required.

How can compatibility with a holder be verified?
Compatibility depends on the holder’s form, free angle, tolerance class, fastening method, size and thickness; matching these parameters to the ISO‑standard insert ensures correct seating and secure clamping.

How does the chip control perform with this insert?
The double‑sided chipbreaker provides consistent chip formation in stable setups, improving evacuation and enabling reliable machining when combined with a suitable cutting strategy.

What does the 0.8 mm corner radius mean for my process?
A 0.8 mm corner radius increases edge strength and resistance to chipping, which is beneficial for interrupted cuts and tougher materials while still permitting acceptable surface finishes.
