CNMG 120404 AH8005 – Turning insert (Tungaloy)

CNMG120404 AH8005 Tungaloy insert for ISO-standard turning applications, designed for stable machining of heat-resistant alloys and hard materials

• PVD-coated carbide grade AH8005
• CNMG rhombic geometry for versatile turning
• Double-sided chipbreaker for longer life
• 0° rake and 0.4 mm corner radius for precision

High wear resistance for demanding turning operations

The PVD-coated carbide grade AH8005 delivers elevated wear resistance and edge stability when machining heat-resistant alloys and other hard workpiece materials. The coating technology reduces flank wear under sustained temperatures, which translates into longer tool life and fewer index changes. For production environments where consistency matters, this performance helps to lower tooling costs per part and maintain cycle-time reliability. Compatibility to a suitable toolholder is determined by form, clearance angle, tolerance class, fixing method, size and plate thickness, ensuring the system performs as a whole.

Geometry and dimensions that support precision and versatility

The rhombic CNMG geometry with a corner radius of 0.4 mm and an included angle of 80° offers a balance between strength and finishing capability. The 0° rake angle provides a stable cutting edge in heavier cuts and difficult alloys, while the double-sided chipbreaker extends usable life by allowing reversible indexing. A cylindrical hole and a plate thickness of 4.76 mm ensure secure clamping in compatible holders and boring bars. These design choices make the insert suitable for both external and internal turning tasks where predictable chip control and surface quality are required.

Practical selection and application advice for process reliability

Choose the appropriate chipbreaker style and the grade AH8005 to match the workpiece alloy, machining type and machine stability; the double-sided design offers cost-effective reversibility for batch production. The insert is delivered to ISO dimensions so that existing ISO-compatible holders and clamping systems can be used provided the form, clearance and tolerance class match. For complex or mixed-material batches, consider the balancing of feed and depth of cut to keep temperatures and tool stress within the grade’s operating window. The wear-resistant nature of the PVD-coated carbide helps to maintain surface finish and dimensional repeatability over longer tool life.

FAQ

What materials is this insert designed for? The CNMG120404 AH8005 Tungaloy insert is designed for machining heat-resistant alloys and other hard materials thanks to its wear-resistant PVD-coated carbide grade.

Can the insert be used for internal and external turning? Yes, the rhombic CNMG geometry and secure clamping via the cylindrical hole make the insert suitable for both external and internal turning operations when mounted in compatible holders.

How does the double-sided chipbreaker benefit production? A double-sided chipbreaker allows the insert to be indexed to a fresh edge, increasing lifetime per insert and reducing tooling costs in batch production scenarios.

Which holder characteristics must be checked for compatibility? Ensure the holder matches the insert form, clearance angle, tolerance class, fixing method, size and thickness; these dimensions determine correct fit and secure clamping.

Is the corner radius suitable for finishing passes? The 0.4 mm corner radius offers a compromise between strength and the ability to achieve fine surface finishes on controlled finishing passes.
