WNMG 080404 AH8005 turning insert — PVD-coated carbide, trigon 80°

A WNMG080404-HRM AH8005 ISO turning insert engineered for external and internal turning of heat-resistant alloys and other hard materials where stable cutting and extended tool life are required.

• PVD-coated carbide AH8005 for high wear resistance
• Trigon (WNMG) 80° geometry for stable turning
• 0.4 mm corner radius for predictable chip control
• Cylindrical hole mounting, ISO-compatible insert

Longer tool life for demanding materials

The combination of a PVD-coated surface and the AH8005 carbide grade provides higher resistance to abrasive and thermal wear, which leads to more consistent performance in extended runs. For operations on heat-resistant alloys and other hard workpiece materials, the coating reduces flank wear and preserves the cutting edge for longer, meaning fewer disruptions for tool changes and improved process reliability. This results in better overall equipment efficiency and lower per-part tooling cost.

Geometry and chip control for stable machining

The trigon insert geometry with an 80° included angle and a 0° relief angle gives a robust cutting edge that resists deflection during heavy cuts. The HRM chipbreaker paired with the 0.4 mm corner radius supports predictable chip formation and evacuation in both roughing and finishing passes. For machinists, this translates into improved surface finish and reduced risk of built-up edge, provided the insert is matched to the workpiece material and the holder offers adequate rigidity.

ISO compatibility and straightforward integration

Designed as an ISO-standard insert, the WNMG080404-HRM fits into common external holders and boring bars when holder shape, clearance, tolerance class, fastening and plate thickness match the specification. The insert features a cylindrical hole for secure mounting and a plate thickness of 4.76 mm, simplifying retrofit into existing tool systems. Using standardised inserts helps maintain process repeatability and eases inventory management across workshops.

Practical application advice for productivity gains

Optimise cycle times by selecting the appropriate chipbreaker and matching cutting parameters to machine power and part stability; this insert is intended for external and internal turning where a stable setup is achievable. When installed in a rigid holder and combined with suitable feeds and speeds, users can expect fewer interruptions for index changes and consistent dimensional results, supporting higher throughput and predictable tool life for batch production.

FAQ

What materials is this insert optimised for?
The WNMG080404-HRM AH8005 is optimised for heat-resistant alloys and other hard materials; the PVD-coated carbide composition provides enhanced wear resistance for these applications.

Can the insert be used for both external and internal turning?
Yes — the design and mounting style make the insert suitable for both external and internal turning operations when combined with an appropriate holder and stable setup.

How does the HRM chipbreaker affect machining?
The HRM chipbreaker promotes controlled chip formation, improving evacuation and reducing the chance of built-up edge; in practice, this supports better surface finishes and predictable cutting forces.

What mounting features should a compatible holder have?
A compatible holder must match the insert form, size, thickness and fastening arrangement; the insert’s cylindrical hole and ISO designation should be verified against the holder specifications.

Is this an original Tungaloy product and how is it identified?
The insert is an original Tungaloy product identified as WNMG080404-HRM AH8005 with manufacturer article number 6741701 and SKU 6741701-Tungaloy.
