WNMG 080408 AH8005 – ISO indexable insert for turning by Tungaloy

WNMG080408-HRF AH8005 is an ISO-indexable insert designed for external and internal turning, optimised for heat-resistant alloys and hard materials.

• WNMG 080408 trigon insert
• PVD-coated carbide AH8005 for heat-resistant alloys
• 0° clearance angle with HRF chipbreaker
• 4.76 mm insert thickness, cylindrical hole fixing

Predictable geometry for repeatable turning performance

The WNMG080408-HRF combines a stable trigon form with a defined 0.8 mm corner radius to deliver predictable cutting behaviour. The trigon shape gives three usable cutting edges per index, reducing tool change frequency and improving uptime. The 0° clearance angle and central, cylindrical hole fixing ensure secure clamping in ISO-compatible holders, which translates into consistent chip formation and repeatable dimensions during both external and internal turning operations. For production environments where process stability is crucial, this geometry supports reliable cycle times and repeatable part quality.

Grade and coating engineered for demanding materials

The insert uses the AH8005 grade, a PVD-coated carbide designed to resist abrasive and thermal wear when machining heat-resistant alloys and other hard materials. The PVD layer improves edge integrity and reduces adhesion, helping to extend tool life under elevated cutting temperatures. In practice, the wear-resistant nature of this grade supports longer uninterrupted runs and reduces the frequency of index changes, which improves productivity and lowers operating costs. Where surface finish and tool life matter, the combination of carbide substrate and PVD-coated protection offers a reliable balance between performance and economy.

System compatibility and operational benefits in the shop

As an ISO-norm insert, the part integrates into standard turning systems that accept WNMG geometry; compatibility is determined by insert form, clearance, tolerance class, fixing method and thickness. The HRF chipbreaker is matched to stable cutting conditions and helps control chip shape for safer evacuation and reduced secondary operations. With a 4.76 mm plate thickness and a cylindrical hole fixing method, the insert sits securely in many external holders and boring bars, contributing to improved process reliability. Selecting the appropriate chipbreaker and grade for the component material and machine rigidity enables a concise cost-benefit outcome: longer tool life, fewer interventions, and consistent part quality.
