WNMG080408-HRM AH8005 (WNMG 080408) – ISO turning insert for Turning by Tungaloy

The WNMG080408-HRM AH8005 is an ISO-standard indexable insert engineered for stable external and internal turning of heat-resistant alloys and other hard materials, offering a robust chipformer and secure clamping via a cylindrical hole.

• PVD-coated carbide AH8005 for long life
• ISO WNMG plate, trigon form, 80° shape
• 0.8 mm corner radius for precision turning
• Cylindrical-hole plate, 4.76 mm thickness

Durable wear resistance for heat-resistant alloys

The PVD-coated carbide grade AH8005 provides a hard, thin coating that reduces adhesion and oxidation at elevated cutting temperatures, which results in improved wear resistance and longer tool life when machining heat-resistant alloys and other tough materials. PVD (physical vapour deposition) creates a uniform layer that helps maintain the cutting edge under thermal stress; this supports stable cutting conditions and more consistent component tolerances during medium to heavy-duty turning.

Geometry designed for repeatable surface quality

A 0.8 mm corner radius combined with the WNMG 80° geometry balances edge strength and surface finish, making the insert suitable where dimensional stability and controlled roughness are required. The trigon plate form offers three effective cutting edges per indexable plate, while the 0° relief angle ensures compatibility with a wide range of holders designed for ISO WNMG plates. Corner radius selection affects both load capacity and finish: the 0.8 mm radius increases edge robustness while still enabling fine external and internal contours.

System compatibility and secure clamping for production use

The insert’s cylindrical hole design and standardised dimensions (ISO 080408) simplify interchangeability with matching external holders or boring bars, using the correct shim or clamping set and replacement screws. Plate thickness of 4.76 mm and standardised form factor help achieve stable clamping forces and repeatable seating. In practice, a turning system comprises the ISO insert, a suitable external holder or boring bar, a matching underlay or clamp set, and fastening hardware; correct pairing of chipbreaker and grade to workpiece material is essential for predictable chip control.

Productivity and process reliability through predictable behaviour

By combining a wear-resistant coating with a robust geometry and standardised form, this insert supports higher cutting speeds and reduced downtime through fewer index changes. Improved chip control from the HRM chipformer lowers the risk of built-up edge and interruptions, contributing to efficient cycle times and lower unit cost in continuous production. The standardised ISO design also simplifies stocking and rapid replacement, enhancing process security and reproducibility in series turning operations.

FAQ

What materials is this insert suited for?
The AH8005 grade with PVD-coated carbide is developed for machining heat-resistant alloys and other hard materials, providing wear resistance and thermal stability for sustained turning operations.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm radius increases edge strength and improves resistance to chipping under heavier cuts, while still enabling acceptable surface finish for general turning tasks.

Is the insert compatible with standard WNMG holders?
Yes, the ISO designation 080408 and the trigon form ensure compatibility with holders designed for WNMG plates, subject to matching form, relief angle and clamping method.

What advantages does the HRM chipbreaker offer?
The HRM chipformer provides controlled chip segmentation for stable removal and reduced risk of built-up edge, supporting uninterrupted machining cycles and consistent component quality.
