DNMG150404 AH8005 indexable turning insert by Tungaloy — PVD-coated carbide for turning

The DNMG150404 AH8005 is an ISO rhombic indexable turning insert engineered for stable, wear-resistant machining of heat-resistant alloys and other demanding workpieces during external and internal turning operations.

• PVD-coated AH8005 carbide for wear resistance
• ISO DNMG150404 rhombic geometry, 55° lead angle
• 0.4 mm corner radius for precise surface finish
• Double-sided insert with cylindrical locating hole

High wear resistance for demanding materials

The PVD-coated AH8005 grade provides a consistent balance between hardness and toughness, making this insert especially suited for machining heat-resistant alloys and harder materials under steady cutting conditions. The combination of a PVD-coated surface and a carbide substrate reduces flank wear and extends tool life, which translates into fewer tool changes and improved uptime. This effect is particularly beneficial in batch production and serial turning where reproducible results and reduced tooling costs are priorities.

Geometry and mounting that ensure precision

Designed in the ISO DNMG150404 format with a rhombic plateform and a 55° lead angle, the insert offers predictable cutting forces and accessible orientation for both external and internal turning. The 0.4 mm corner radius contributes to a refined surface finish while maintaining edge strength during finishing passes. The insert is supplied with a cylindrical locating hole, ensuring secure clamping and repeatable positioning in compatible holders and boring bars. Clear attention to form, relief angle and tolerance class supports straightforward integration into existing tool systems.

Productivity advantages and process reliability

Built for stable cutting, this indexable tool reduces vibration and provides consistent chip control when paired with the appropriate holder and clamping set. The double-sided chipbreaker allows economical use of both cutting edges before replacement, lowering cost per cut. Stable machining dynamics result in improved cycle times and more predictable batch quality, a rational advantage for shops focusing on throughput and margin. For customers seeking demonstrable process benefits, this insert improves machining consistency without increasing setup complexity.

Selecting the right grade and handling recommendations

The AH8005 grade is optimised for heat-resistant alloys and hard materials under stable machining conditions; for interrupted cuts or less rigid setups a different chipbreaker or a more impact-tolerant grade may be preferable. When mounting, ensure compatibility by matching the holder’s form, relief angle, tolerance class, fastening method, size and thickness to the insert’s ISO parameters. For further guidance on insert selection, cutting parameters and holder pairing, the supplier can provide technical data and practical tips to ensure the best combination of performance and tool life.
