CNMG 190616 AH8005 – Turning indexable insert by Tungaloy

The CNMG190616 AH8005 is an ISO rhombic, PVD-coated carbide indexable insert designed for precision external and internal turning in stable machining conditions.

• PVD-coated wear-resistant grade AH8005
• Rhombic CNMG geometry, 80° lead angle
• Double-sided chipbreaker for consistent chips
• Central cylindrical hole, secure clamping

Higher process reliability through optimised grade and coating

The combination of a PVD-coated surface and the AH8005 wear-resistant grade is engineered for demanding materials such as heat-resistant alloys and other hard workpieces. This chemistry reduces flank and crater wear under elevated temperatures, permitting longer cutting intervals and improved repeatability in series production. The robust substrate of the carbide body sustains mechanical stability during interrupted cuts, while the 1.6 mm corner radius contributes to a reliable cutting edge that balances edge strength and surface finish. As a result, machining cycles become more predictable and tool change frequency is reduced, which benefits throughput and machine availability.

Secure clamping and consistent chip control for reduced downtime

The rhombic CNMG geometry with an 80° lead angle and a double-sided chipbreaker provides well-shaped chips across a wide range of feeds and depths of cut. The insert’s central cylindrical hole enables positive, repeatable clamping in ISO-compatible tool holders and the 6.35 mm plate thickness increases bending resistance under heavy cuts. These mechanical features together generate stable toolholding and consistent chip formation, which simplifies chip evacuation and reduces the risk of re-cutting. In practice this leads to fewer interruptions for chip clearing and a steadier surface quality on turned components.

Practical uses and selection guidance for reliable results

Designed for turning operations, the insert performs particularly well in external and internal turning on tougher materials where thermal and mechanical loads are high. The double-sided design offers two usable cutting edges per side, extending edge life and offering economical performance in production environments. For finishing and semi-finishing, the 1.6 mm corner radius gives a balanced compromise between dimensional control and edge robustness; for heavier roughing tasks, selecting a matching chipbreaker and optimising cutting data will exploit the grade’s wear resistance. For assistance in selecting the ideal chipbreaker and cutting parameters, technical advice is available to ensure the insert suits the specific workpiece material and machine setup.

FAQ

Which materials is this insert designed for?
The CNMG190616 AH8005 insert is specified for wear-resistant machining of heat-resistant alloys and other hard materials where a hard-wearing PVD-coated carbide grade brings advantage.

Can the insert be used for both external and internal turning?
Yes, the rhombic geometry and central cylindrical hole allow secure clamping in ISO holders for both external and internal turning operations.

How many cutting edges are available per insert?
This double-sided design provides multiple usable edges; the reversible geometry increases the number of effective cutting edges compared with single-sided inserts.

What are the key dimensions to check for holder compatibility?
Important dimensions include the inscribed circle (19 mm), thickness (6.35 mm) and the corner radius (1.6 mm); these determine fit and the achievable edge strength.

How does the AH8005 grade affect machining strategy?
The AH8005 wear-resistant grade with its PVD-coated surface supports higher-temperature resistance and longer edge life, enabling more consistent cycle times and less frequent index changes.
